This is a very nice HYDROTHERMAL emerald...Round shape...5mm...Colombian green color.Quality C ( SI++)
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.

なぜユーザーは自分自身を上回る入札をするのでしょうか?
入札する場合、これはユーザーが製品に入札する意思のある最大金額です。その後、当社のシステムがそのユーザーに代わって自動的に入札し、最高入札者としての地位を維持するために、指定された最大値まで入札額を段階的に引き上げます。
「自動入札」を示すアイコンがある場合、システムが最高入札額に基づいてユーザーに積極的に入札していることを意味します。これは、ユーザーが自分自身を上回って入札しているように見えるかもしれませんが、ユーザーの上限を反映するためにシステムが入札を更新した結果にすぎません。
