About Hydro-Emerald

What is Hydrothermal Emerald?

Hydrothermally grown synthetic emeralds crystallize slowly out of a solution (a mix of water and dissolved elements) that has been exposed to heat and pressure similar to the conditions on Earth under which the natural gem mineral grows. Synthetic gems have the same chemical, optical, and physical properties of their natural counterparts, but are a more cost-effective alternative to a natural gem.

How about Starsgem's Hydrothermal Emerald?

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.
