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.

Warum überbieten sich Nutzer selbst?
Bei Abgabe eines Gebotes handelt es sich um den Höchstbetrag, den ein Nutzer für das Produkt zu bieten bereit ist. Unser System bietet dann automatisch im Namen dieses Benutzers und erhöht das Gebot schrittweise, um seine Position als Höchstbietender bis zum angegebenen Höchstbieten zu halten.
Wenn das Symbol „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Benutzer auf der Grundlage seines Höchstgebots abgibt. Dies mag so aussehen, als ob die Nutzer sich selbst überbieten würden, aber es liegt einfach daran, dass das System das Gebot aktualisiert, um das Höchstlimit des Nutzers widerzuspiegeln.
