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.

14x10 mm emerald cut
 
These three two lab emeralds are cut in a 14x10-mm rectangular octagon shape. They are clean, bright, nicely colored gemstones.  Because it is difficult to grow thick lab emerald crystals, the depth of these stones is somewhat less than ideal, relative to the length/width.  This is not as important in emeralds as in stones with a higher refractive index, and emeralds are cut mainly for the color rather than for the dispersion of light.   The average weight is 4.75 ct. Priced at $75/ct.  The price shown at right is per gemstone.
