For the hundreds of thousands of devotees now engaged in this relatively new craft, here are the newest and most comprehensive techniques and information based on the combined experience of two leading experts in the field.
Beginning with a description of the properties and physical characteristics of gems, including synthetics and imitations, the authors show the craftsman how to get started, the equipment needed, how to saw, grind, lap, sand, and polish. They cover the grinding and polishing of cabochons, the cutting and polishing of faceted stones, with a special helpful section on dopping, carving and sculpturing gemstones, mosaic and intarsia, plus special polishing problems of gemstones.
Gemstone novelties are also included, such as bookends, clocks, lamps, ashtrays, agate handled silverware, dishes, and many others. One of the highlights of Gemcraft is the chapter on where and how to collect gemstones. Indispensable for the collector, this section is packed with interesting information. The chapter on special lapidary techniques and shortcuts is very valuable. The many clear, step-by-step photographs presenting every important process in gemcraft and the extensive bibliography and complete index make this the finest, most thorough book on the subject published.

The Tutorial
(via Wahroongai News, Volume 32, Number 4, April 1998) Grahame Brown writes:
Traditional tutorials were one-to-one periods of instruction given by masters to students at university colleges. Today the role of the tutorial has been expanded to include those small group teaching sessions, of four or less students, that are primarily devoted to a critical and searching discussion of subject matter—but are particularly concerned with developing each student’s independent intellectual powers. The tutor’s principal task in a tutorial is to use subject matter to what he or she considers its best advantage to stimulate, develop, and maximize the individual student’s powers of thought, analysis, and self-expression.
In the tutorial the tutor’s role is likely to be a dominant one; for the tutor’s major task is to direct student understanding, and student learning. To that end, tutor’s must pose relevant searching questions, check and analyze student responses to those questions, and direct student learning to remedy any perceived errors of fact, concept, and/or analysis.
Tutorials serve three broad purposes in authority-based (as opposed to self-directed) learning:
- They provide a regular meeting place for checking student progress.
- They provide a very effective means for discovering misunderstandings in larger format methods of instruction, such as lectures and demonstrations to more than five individuals.
- They provide an opportunity for detailed scrutiny of a particular piece or aspect of the student’s work.
However, the much underrated pastoral role of the tutor never should be neglected; for the tutorial format offers the tutor a unique opportunity to inject some humanity into the educative process. Problems can be discovered, and suitable remedies suggested and implemented—taking into full consideration the personality of the student, their progress in their peer academic group, and any private matters that may or may not be affecting the student’s progress.
Advantages offered by the tutorial are that:
If focuses attention on the work of the individual student and his or her ways of thinking.
It allows the tutor to keep a close eye on each student’s progress.
It provides essential continuity in the tutor-student relationship.
Disadvantages of the tutorial are that:
It can be very demanding of time, both for the student and the tutor.
The tutor has a dominant role in the educative process.
Conclusion
Used intelligently and selectively the tutorial is an effective educational tool—provided tutors are knowledgeable, and adequately trained to pose the right questions required to stimulate the independent intellectual powers of the student. Of course, tutorials will fail if students do not think, research, write answers to the questions their tutors pose.

Memorable quote (s) from the movie:
Professor Henry Higgins (Rex Harrison): I know your head aches; I know you're tired; I know your nerves are as raw as meat in a butcher's window. But think what you're trying to accomplish. Think what you're dealing with. The majesty and grandeur of the English language, it's the greatest possession we have. The noblest thoughts that ever flowed through the hearts of men are contained in its extraordinary, imaginative, and musical mixtures of sounds. And that's what you've set yourself out to conquer Eliza. And conquer it you will.

Ageing Is When.......
(via Wahroongai News, Volume 24, No.6, June, 1990)
Everything hurts and what doesn’t hurt, doesn’t work.
You feel like the night after, and you haven’t been anywhere.
You get winded playing chess.
You little black book contains only names ending in M.D.
Your children begin to look middle-aged.
You’re still chasing women but can’t remember why.
You know all the answers, but nobody asks you the questions.
Your knees buckle and your belt won’t.
You stop looking forward to your next birthday.
You burn the midnight oil until 9:00 pm.

How Well Do You Know Jewelry?
(via JQ magazine, July/August 1996) Naaz Aalund writes:
The questions in this quiz have been gathered from experts in the jewelry industry as the most often asked questions. While some of the multiple choice answers contain correct information, the right answer is the one that concisely presents the best information to the customer.
Have fun.
1. Are platinum and white gold the same thing?
a. There is no true white gold
b. There is no difference—they are the same thing.
c. Platinum is a noble metal that is naturally white, while white gold is combined with zinc, nickel and silver to give the naturally yellow gold a white color.
d. Platinum is more rare, more pure, more dense and more demanding to work with, so it’s more expensive.
Answer: c
2. Are tanzanites too fragile to wear in rings?
a. No. Wear them all the time and don’t give it a second thought.
b. Yes. Tanzanite should only be worn in pendants and earrings.
c. Tanzanites are thermo-sensitive, so it is not advisable to wear them while cooking.
d. Tanzanites are 6.5 on the Moh’s hardness scale, which means if they are not cared for properly, they may get scratched. Opals are only a 6, and pearls are only a 3, so if they can be worn in rings, so can tanzanite.
Answer: d
3. With colored gemstones, is darker always better?
a. Intensity of color is all a matter of personal preference.
b. Intensity of color is good even if the gemstone is so dark that color and light can no longer be seen in it.
c. Actually, lighter is better—as with diamonds, colorless is best.
d. Intensity is good up to a point. When a gemstone becomes too dark, it is not as valuable.
Answer: d
4. Is eighteen karat gold too soft? Is fourteen karat gold stronger?
a. Only fourteen karat gold is tough enough to take daily wear.
b. High quality jewelry is made heavy enough for eighteen karat gold to be acceptable.
c. In tests done on eighteen karat and fourteen karat gold, both wore evenly under similar conditions, with fourteen karat showing cracking from fatigue more quickly than eighteen karat.
d. Fourteen karat is best for thin wire jewelry.
Answer: c
5. Are diamonds the rarest of gemstones?
a. De Beers maintains a limited supply and keeps demand high with advertising.
b. Rarity is dependent on many factors, including color, carat weight and clarity. Often a ruby, spinel, or tsavorite of exceptional quality will be more rare than an average diamond.
c. A ‘D’ color flawless diamond is not only the rarest of diamonds; it is also the most rare of all gemstones.
d. Rarity of a gemstone is dependent upon whether the gemstones can be made in a laboratory.
Answer: b
6. Can a ring be sized to any size, larger or smaller?
a. No problem. Gold is a very flexible metal, and it can be bent easily.
b. A ring can be sized smaller much more easily than it can be sized larger.
c. The goldsmiths can compress or stretch the gold as needed to make a ring smaller or larger.
d. Sizing a ring more than two sizes larger or smaller may structurally damage the ring and cause gemstones to break or fall out.
Answer: d
7. What is the difference between precious and semi-precious gemstones?
a. Precious gemstones are diamond, ruby, emerald and sapphire; everything else is semi-precious.
b. Rarity and beauty determine a gemstone’s value. An extremely large Paraiba tourmaline would be more valuable, and thus more precious, than a pale and included emerald. These terms precious and semi-precious do not truly indicate a gemstone’s value.
c. Semi-precious gemstones include cubic zirconia, synthetic sapphires and emeralds and all laboratory grown gemstones, while precious gemstones are all natural.
d. Precious gemstones are the twelve birthstones, one for each month of the year, and semi-precious are the gemstones that aren’t birthstones.
Answer: b
8. Why is platinum jewelry so much more expensive than gold?
a. Platinum is more demanding to work with, so it requires greater skill in manufacturing, making labor more expensive.
b. Platinum is twice as dense as fourteen carat gold. In jewelry that is the same size and shape, platinum will weigh more, making it more expensive.
c. Platinum is 90 percent pure platinum. Whereas fourteen carat gold is only 58 percent pure gold, platinum is alloyed with iridium, another platinum-family metal which keeps its value high.
d. All of the above.
Answer: d
9. Why does it take 4-6 weeks to custom-make a jewelry item?
a. At any given time, a designer and his staff may be making 200 pieces of jewelry or more, so for a client’s job to get the attention it needs, other work must be cleared away first.
b. In each step of the jewelry making process, there is a specialist that must complete her part of the job to the best of her abilities for the jewelry item to have the high quality of craftsmanship the client deserves.
c. Jewelry is still in large part made by hand by craftsmen and women who have practiced their craft for a lifetime to achieve mastery. Yet even the finest master craftsperson, when rushed, may overlook flaws that compromise quality.
d. All of the above.
Answer: d
10. Why can’t I wear my jewelry all the time? If it’s good quality jewelry, shouldn’t it last even when I wear it during sports and to bed?
a. Jewelry last hundreds of years and never wears out. Don’t worry about wearing your jewelry all the time.
b. Like a fine silk blouse or a mink coat, jewelry and gemstones can be damaged if not cared for and worn properly.
c. The investment you have made in your jewelry will be lost if you wear it in way that will damage it.
d. Like everything that is around us, things will wear out and, unfortunately, jewelry is no exception. To minimize the wear and tear that can detract from your jewelry’s longevity and beauty, it is advisable to remove it during activities and at bedtime.

Chiastolite
(via Wahroongai News, Volume 24, No.3, March 1990) Australian Amateur Mineralogist writes:
One of the most intriguing minerals found in interior Australia is the chiastolite of Australian Cross Stone. In nature, the mineral occurs as cigar-shaped crystals in slates which have been ‘heat treated’ by invading granites. Crystals mostly average about 3 or 4 inches in length by an inch in diameter. As they weather from their micaceous (schistose) host rock, they have little obvious beauty. Their shape alone may attract attention.
When broken, an internal cross from is revealed traced in shades of gray, white and sometimes a delicate pink. When cut and polished, true gem status is achieved, and selected examples were once quite popular in the jewelry trade. Like most Australian gem industries, however, indiscrete swamping of markets, careless preparation, and lack of suitable advertising propaganda ruined any wide market possibilities even before they materialized. Its fate was a dismal as the Harts Range ‘rubies’ (or garnet). Even opal had from time to time suffered from similar Australian carelessness. Opal, however, now seems to be enjoying more rewarding popularity on its own merits.
Chiastolites of good internal form occur in but few places in the world, and of these the Bimbowrie Station examples from the Olary district in South Australia undoubtedly are of outstanding quality. At one time, fine specimens could be collected in quality strewn about the slopes of the low schistose hills of the locality. Shearers passing by repeatedly collected them in sugarbags full and returned them to their friends and relatives in the cities. They received wide appeal, but after a time their very abundance weighed against them. Now the picture is different. The old localities are largely worked out as far as surface occurrences are concerned. A day’s collecting will certainly provide many tens of pounds of them, but good ones are no longer over plentiful. Now it appears the stage may be set for real appreciation. The jewelry trade will soon realize their potential.
The origin of these freaks of nature, as indeed they are, is interesting. The mineral is a form of andalusite, a relatively common mineral in the field. In composition, it is a silicate of aluminum, or chemically, Al2SiO5. The reason for its interest is, of course, the cruciform internal structure—a factor of interest, particularly in matters of Christian religion—but also for beauty in its own right.
The cross structure is related to the method of growth of the individual crystal in the presence of minute amounts of carbon as impurities in the enclosing rock medium. The crystals actually grow at the expense of the enclosing aluminous sediment—a redistribution of the alumina and silica of the argillaceous slate occurring to form the crystals. In the present examples small amounts of carbonaceous material occur along with these substances which are excess to the growing crystals requirements. The effects of solution and heat responsible for the minerals growth were not sufficient to remove the carbonaceous matter so they were just pushed aside into less inconvenient situations with in the developing crystal structure.
In this way, the square form of the crystal in section (the mineral crystallizes in the orthorhombic system) imposes a cruciform distribution of the reconcentrated carbon material and leaves other areas relatively free of this substance, and therefore lighter in color.
Actually, the crystal effects redistribution of the carbon in two major patterns, both of which form ‘crosses’ of a type. One is called the ‘Howdenite’ after Mr J Howden, their prospector-discoverer, and the other is unnamed.
Prof Mawson, in his writings on ‘The Geology of the Broken Hill Area’, has dealt with this subject in great detail and earlier in this century produced excellent color reproductions of them.

Memorable quote (s) from the movie:
Miles Raymond (Paul Giamatti): What about you?
Maya (Virginia Madsen): What about me?
Miles Raymond (Paul Giamatti): I don't know. Why are you into wine?
Maya (Virginia Madsen): Oh I... I think I... I originally got in to wine through my ex-husband.
Miles Raymond (Paul Giamatti): Ah.
Maya (Virginia Madsen): You know, he had this big, sort of show-off cellar, you know.
Miles Raymond (Paul Giamatti): Right.
Maya (Virginia Madsen): But then I discovered that I had a really sharp palate.
Miles Raymond (Paul Giamatti):Uh-huh.
Maya (Virginia Madsen): And the more I drank, the more I liked what it made me think about.
Miles Raymond (Paul Giamatti): Like what?
Maya (Virginia Madsen): Like what a fraud he was. No, I- I like to think about the life of wine.
Miles Raymond (Paul Giamatti):Yeah.
Maya (Virginia Madsen): How it's a living thing. I like to think about what was going on the year the grapes were growing; how the sun was shining; if it rained. I like to think about all the people who tended and picked the grapes. And if it's an old wine, how many of them must be dead by now. I like how wine continues to evolve, like if I opened a bottle of wine today it would taste different than if I'd opened it on any other day, because a bottle of wine is actually alive. And it's constantly evolving and gaining complexity. That is, until it peaks, like your '61. And then it begins its steady, inevitable decline.
Miles Raymond (Paul Giamatti): Hmm.
Maya (Virginia Madsen): And it tastes so fucking good.
