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.

Perché gli utenti superano se stessi?
Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
