Think about..... Separating the true gemologists from the ordinary gemologists: Why ordinary graduate gemologists cannot have access to database on analytical instrumentation used by the leading commercial gemological labs and institutes? Re-examine the different types of diffusion taken place upon heat-treating gems. What are the criteria to interpret correctly the diffusion phenomenology in ruby-sapphire? Why the hydrogen diffusion in corundum is excluded from calling these stones "hydrogen diffusion-treated", like the "beryllium diffusion-treated corundum"? How about those diffusion treated gems due to irradiation treatment? How about the flux and other additives used in filling the cracks/cavities in Mong-Hsu rubies? How about the oiling of emeralds? Who takes advantage of the situation? Who are the losers? Why the trade avoid such questions? Why the trade intentionally distort the meaning on the disclosure of gem treatments? Why jewelers keep quiet on the treatments of diamonds and who are the benefactors? |
Gray area 1. Is beryllium a chromophor" in the heat-treating process of papaya-colored sapphire? What causes the intense "neon" orange and other colors on these Be-treated sapphires? Bear in mind that beryllium is found in natural, untreated corundums from Thailand, Madagascar, Tanzania and Burma. |
|
Gray area 2. Define "traditional", "non-traditional" treatment methods in heating corundum. How about a gem classification based on these degree on these criteria? |
|
Gray area 3. What are "permissible" and "non-permissible" gem treatments? |
Read my book Gem Treatments & Enhancements (in print) |
Gray area 4. Define "permissible" and "non-permissible" treatments on processes using fluxes in heating ruby-sapphire and other gems. |
|
Gray area 5. Correct the term "diffusion-treated sapphires" erroneously introduced by GIA in early-1980's (Gems & Gemology, "Diffusion-Treated Sapphires") and prevailed in the trade for over 20 years. Diffusion process of irradiated and heat-treated gemstones. |
Working on it.. |
Gray area 6. What are the "permissible" and "non-permissible" filling substances in treating emeralds? |
|
Gray area 7. Define the meaning of "padparadscha" sapphires and separate them from their similarly appearing African orange sapphires. |
|
Gray area 8. Define the criteria which distinguish a "Ruby" from a "Pink Sapphire". |
|
Gray area 9. Define criteria that distinguish a "Rubellite" from a "Pink Tourmaline". |
|
Gray area 10. Define criteria that distinguish an "Emerald" from a "Green Beryl". |
|
Gray area 11. What is a "pigeon-blood ruby"? or a "cornflower-blue" sapphire? |
|
Gray area 12. What do you mean "glass-filled ruby?", "Ruby with glassy-fissures? |
|
More gray areas. Why Mogok rubies are not specifically stated as "Mogok, Burma" in the Gemstone Reports issued by many commercial gem laboratories? Why the Mong-Hsu rubies (also from Burma) fetch much lower value than their Mogok counterparts? Why the commercial gemlabs deliberately confuse the issue? Who benefits from such misinterpretation, mispresentation and confusion? By the same logic, why "Kashmir sapphires" are not termed as "Indian sapphires?" |
