Emerald Lab Grown Synthetic Gemstones

HydroEm02.jpg (38549 bytes)

Emeralds are the familiar "Emerald Green" members of the beryl family of faceted gemstones.  Our lab grown or created synthetic emerald gems are synthesized by the hydrothermal method. They have the same composition and physical properties, but have higher perfection than is usually seen in natural emeralds or man made flux-grown emerald cut gems.  Beryl is beryllium aluminum silicate with the chemical composition Be3Al2(SiO3)6. Other members of this family include aquamarine (sea greenish-blue), morganite (pink/peach), heliodor (yellow/golden-yellow), red beryl (very rare), and goshenite (clear, colorless). The colors of beryl are caused by dopant atoms present in small amounts -- in the case of emerald these dopants are chromium and/or vanadium.  A hydrothermal emerald crystal and some cut gemstones are shown at left.  We are able to offer lab-grown emerald gemstones at a small fraction of the cost of comparable natural emerald stones.   We can also set these gemstones for you in silver or gold jewelry mountings.  Ask for details.  You can click on any underlined Item # to see a photo of the gem.  Use your browser's "back" button to return to the list.
