Malaya Zircon

The Malaya zircons originate from the area of the Bombo river, which is a tributary of the Umba river. Mining is active in a region between Mkujani and Umba in the Tanga Province, Tanzania. The colors range from yellow to brown and red. Most specimens are found as water-worn pebbles. Alluvial stones could easily be confused for corundum, chrysoberyl, garnet, or spinel. Gem quality specimens when faceted show good transparency and brilliance. The stones may be heat treated to modify colors. If in doubt, always consult a reputed gem testing laboratory.
