About Emerald

                                                       HYDROTHERMAL EMERALD

Today you can find all sorts of Lab Created Gemstones in the market like lab created ruby, lab created sapphire, lab created alexandrites. Out of all these Lab Created Gemstones, the Lab Created Emerald is considered to be the best discovery made by man. Not everyone can afford to wear a jewellery with real emerald stones as a top quality real emeralds can cost up to $40,000 to $100,000 a carat. But most of the people can afford to wear jewelry with synthetic emeralds in it as you can easily find a top quality lab created emerald at gemsngems for below $100.

The lab created emeralds that we supply here are made by the hydrothermal process that is why some people also call it hydrothermal emerald. This process uses a water solution at high temperatures and it takes many months to create a top grade synthetic emerald rough. We then use specialist engineers to cut these stones from the roughs to get the best grade lab created emeralds. The synthetic emeralds you find here will have the same chemical composition as the real emeralds.

Here at gemsngems – we can cut the lab created emeralds in all shapes and sizes. It is very popular with jewelers as it is used both in silver and gold jewelry. I have all the prices for the synthetic emeralds on this page. If you do not find anything that you are looking for then send me an e-mail at sales04at starsgem.com

COLOR: A very fine green colour that a natural emerald would feel jealous of.

CHEMICAL COMPOSITION: BeAlSiO (BerylliumAluminiumSilicate). Similar to natural Emerald.

CUT: Round Brilliant Cut, Oval Brilliant Cut, Cushion Cut, Square Cut, Rectangular Octagon Cut, Marquise Cut, Trillion Cut, Heart Shape Cut, Pear Shape Cut




FORMATION: Hydrothermal or Flux-fusion lab process. The technique usually involves dissolving the crystal nutrients in an acidic solution of water and chemicals at high temperatures and pressures, with crystallization occurring in a cooler chamber in the reactor.

UNUSUAL PROPERTIES: Synthetic emeralds will have characteristic inclusions diminishing the stone value. A nice synthetic emerald will look like the top quality natural emerald to the untrained eye.Synthetic and natural emerald can be distinguished by their specific gravity, refractive index and opaqueness.

USAGE: Great for Earrings, Rings, Pendants and any other jewellery.

WHAT WE SUPPLY: Synthetic Emerald in different grades and sizes are available with us. We also supply the rough stones of these material.

A: No. There are no likely situations in which the color of moissanite will be permanently changed. Moissanite does undergo a temporary color change when exposed to extreme heat from a jeweler's torch during jewelry repair, but with proper bench techniques there will be no lasting damage, and the stone will return to its normal color once it cools.
