As promised the new generation of heat-treated gems arrived. Ted is now treating with new innovative methodology untreated (or previously treated) rubies, sapphires, spinels, grossulars and other gems utilizing new proprietary method. The treatment enhances color, clarity, transparency, luster and brilliance on selected types of gems. All gems are sold by Ted are stable to light and normal wear (as their untreated counterparts), and they often difficult to detect even by experienced gemologists. Stay tune as the new gemologist's nightmare is around the corner from Dr. FrankenSTONE.
HIGHLIGHTS
The process was developed by Ted Themelis et al after careful observations in heat-treating gems in the past 25 years. This ‘new' method disturbs the lattice in a gem causing internal alterations impoving the color, diaphaneity, luster, brilliance and stability. Only certain types of gemstones emanated from certain geological environments respond well to this new treatment: ruby, sapphire, spinel, grossular and other gems. Also on previously heat-treated gems with beryllium, the new method eliminates the core-rim pattern producing uniform coloration throughout the stone (2nd generation of Be-treated corundum).
Target. The target is to produce a treating method that will improve the general appearance in most gems regardless their chemical composition.
Process. Heating process is using solid and gaseous additives and it is repeatable, irreversible performed between 700oC to 1700oC, slow or rapid coolking.
Addtives. The process uses a unique mixture of non-color-bearing additives and carefull controlled atmosphere conditions perfromed in an electric furnace: Additives Nano -scale size, non-color bearing, non-toxic, non-corrosive, normal handling, soluble in water, non-color bearing, non-radioactive, non-explosive, non-poisonous, non-biohazard.
Detection. In some gems treated with the new method, the treatment is very diffucult to be detected by classic gemologicla instruments.
Stability-durability. The following tests perfomed ion heat-treated rubies, sapphires, spinels and grossulars: Display case, Heat, Jewelry repairs, Setting, Immersion in pickling solution, Prongs re-tipping, Exposure to aggressive solutions, Exposure to household chemicals, Ultrasonic cleaning, Hot steaming, Rhodium plating. After tests, no color alteration is noted on corundum, spinels , tourmalines. No special handling is required. Garnets and zircons behave in the same manner like their untreated counterparts.
Note. At this time no detail technical specifications on our propreitry heating process will be released. |
