This is a very nice HYDROTHERMAL EMERALD...Zambian green color...Pear shape...2,72cts and 12x8mm...A quality...IF/VVS++...
This is a very nice HYDROTHERMAL EMERALD...The green color of the ZAMBIAN natural emerald...Pear shape ...2,72cts and 12,00 x 8,00mm... Our gems have same chemical and gemological properties as their natural counterparts. The only difference is that natural stones are found by men while ours are made by men.We have 3 qualities: A,B,C.:A is IF,B is slithly included and C is little more included.These qualities make the HYDROTHERMAL EMERALD the same as the natural one.
Hydrothermal Process and How it is done |
|||||||||||||||||||||||||||||
Hydrothermal method is based on transformation of melted crashed emeralds and deposit of consequent solution around the beryl seed in a hydrothermal environment. The crashed low grade emeralds, known as nutrient, are melted along with color inducing chemicals, such as Vanadium and Chromium, that are ones of the nature‚s coloring agents in emeralds, and deposited onto a natural beryl seed. The seed, being a larger and more solid element in the process, attracts smaller particles of the same origin and the growth process begins, depositing layer upon layer on itself. This is the reason for undulated growth lines in hydrothermally grown gems. The process takes around four weeks. If the process is slowed down, the “ layers” are deposited at a slower rate, resulting in growth lines being less defined and more difficult to detect. The process starts by gradually heating the autoclave. Subsequent rise in temperature leads to rise in pressure, as a result of liquid expansion inside the inner vessel. Once the temperature rises to about 600 C and pressure is around 800 PSI, the process reaches an ultimate equilibrium and a melt process begins. Smaller particles are attracted by the larger element, the seed, hence starting the growth process.
