Composite vs Assembled Opal
Composite opal
These stones are partly made up of opal and partly of the rock which the opal was found in. The rock may be ironstone, quartzite, sandstone or another matrix. This type also includes pseudomorphs in which the opal has replaced another substance. Composite opal consists of a single mass and should not be confused with assembled stones.
Assembled stones normally consist of two parts (doublets) or three parts (triplets) cemented or fused together for providing a better wearing surface; to obtain a large stone from two smaller pieces of natural material; to produce a stone of apparently better color and appearance; for the purpose of supplying a rigid backing or support for fragile materials.
Doublet
Opal doublets consist of a thin slice of precious opal cemented onto a plastic, black onyx, glass or potch (common opal) back. To lower the cost, the top surface is normally flat. Better (and more expensive) doublets are made with thicker pieces of opal, and the surface is domed. Black cement is used to give a dark background for the translucent opal. This gives the appearance of an expensive black opal. Crystal opal makes the best doublets and gray opal the worst. The identification of doublets is not normally difficult, but one must be careful of opal doublets with a potch backing because some solid opals also have a potch backing.
Triplet
As the name implies, opal triplets consist of three parts. The middle section is a thin slice of precious opal, the back is the same as on a doublet, and the top is usually made of rock crystal quartz or another transparent colorless material. This top piece gives the stone greater durability and also magnifies the play of color, thus increasing the beauty. In general, triplets are worth more than doublets. Clear resin is used to cement the quartz top to the opal, and dark resin to cement the opal to the back. Synthetic opal (Gilson) has also been used in place of natural opal for making opal doublets and triplets.
Opal doublets and triplets are easily identified. Unlike other assembled stones, they are not intended to deceive the buyer. They are produced in order to make use or otherwise useless material, and provide the beauty of a fine solid opal at a fraction of the price.

Sjunde inseglet, Det (The Seventh Seal)
Memorable quotes from the movie:
Antonius Block (Max von Sydow): I want knowledge! Not faith, not assumptions, but knowledge. I want God to stretch out his hand, uncover his face and speak to me.
Death (Bengt Ekerot): But he remains silent.
Antonius Block (Max von Sydow): I call out to him in the darkness. But it's as if no one was there.
Death (Bengt Ekerot): Perhaps there isn't anyone.
Antonius Block (Max von Sydow): Then life is a preposterous horror. No man can live faced with death, knowing everything's nothingness.
Death (Bengt Ekerot): Most people think neither of death nor nothingness.
Antonius Block (Max von Sydow): But one day you stand at the edge of life and face darkness.
Death (Bengt Ekerot): That day.
Antonius Block (Max von Sydow): I understand what you mean.

Opal Origin
Some experts believe trace element analysis + their ratios by Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS) could pinpoint opal source (s).
No Two Alike
Good Books: (via Emergic) Here is how Publisher's Weekly (via Amazon.com) summarizes the book, No Two Alike:
Why do identical twins who grow up together differ in personality? Harris attempts to solve that mystery. Her initial thesis in The Nurture Assumption: Why Children Turn Out the Way They Do is replaced here with a stronger, more detailed one based on evolutionary psychology. Reading this book is akin to working your way through a mystery novel complete with periodic references to Sherlock Holmes. And Harris has a knack for interspersing scientific and research-laden text with personal anecdotes. Initially, she refutes five red herring theories of personality differences, including differences in environment and gene-environment interactions. Eventually, Harris presents her own theory, starting from modular notions of the brain (as Steven Pinker puts it, "the mind is not a single organ but a system of organs"). Harris offers a three-systems theory of personality: there's the relationship system, the socialization system and the status system. And while she admits her theory of personality isn't simple, it is thought provoking. Harris ties up the loose ends of the new theory, showing how the development of the three systems creates personality.
This is what Scientific American wrote (via Amazon.com):
Where does adult personality come from? Why are we all different? These are the questions energizing Judith Rich Harris's new book. Harris then develops a complex scheme based on "the modular mind," a framework set forth by Harvard University evolutionary psychologist Steven Pinker and others. (Harris herself has no doctorate and is housebound by systemic sclerosis and lupus, two autoimmune disorders.) She describes three modules: the relationship system, the socialization system and the status system, and explains how each contributes its part to making us who we are. The relationship system starts in the cradle as infants study and learn the faces and voices of the people around them, collecting information that helps form personality. The socialization system adapts people to their culture. The status system takes all the information collected during childhood and adolescence and shapes and modifies our personalities in accord with our environments.
Harris's last chapter lays out her theory in tabular form, explaining how each module interacts with the others to produce our distinct personalities. It is lavishly footnoted, like the rest of the book, shoring up her strategy of pointing out the failings of other models and then proposing her own. Her goal, she writes, is to explain the variations in personality that cannot be attributed to variations in people's genes.
It's amazing when you try to understand the link between human nature and individuality + the complex mental infrastructure + the distinguishing characteristics. No Two Alike is a fascinating book because it's a story about us and the people around us.

Milton Esterow writes about art thieves in Western Europe + ethnically oriented Balkan bandits + Irish travelers + other viewpoints @ http://artnews.com/issues/article.asp?art_id=1963
Art thieves aren't any different from gem and jewelry thieves. The differences lie in their operating system (s). Gemstones and jewelry are portable, if lucky, easy to liquidate, while paintings require extensive network (s) + the barter culture in certain territories makes it even more complicated.
