I have studied the lattice structures and chemical compounds of crystals: diamond, emerald, ruby, sapphire, tourmaline, citrine, garnet, peridot, spinel, zircon, mossanite, onyx, opal, alexandrite, tanzanite, topaz, morganite, amethyst, aquamarine, quartz, etc.

I understand the processes that natural stones go thru for enhancement. For example, natural Tanzanite is brownish, and turns "blurple" with heat treatment. Laser, irradiation and other processes and substances are used on certain stones for cosmetic enhancement. Emeralds most always have natural cracks, and epoxy, polymers and other compounds are impregnated to minimize the appearance of the fissures. As a result, you never want to steam clean them or they might fall apart.

I am familiar with the various cuts of stones: brilliant (traditional 58 facet), emerald, princess, cushion, pear, heart, oval, marquise, radiant, baguette, trillion, asscher, teardrop, cabochon, old mine, trapezoid, fan, many others, and proprietary cuts like "Lucida" 50 facet, "Ashoka" 62 facets, "Eternal" 81 facets, "Elara" 61 facets, "Sunburst" 145 facets, "ZigZag" , "Dreamscape".

The different cuts will have different yields, thus affecting the price.

I am familiar with stone cutting techniques and principles, and the anatomy of a cut stone ("lapidary science"): table, pavilion, girdle, culet, etc. Optimal angles, depths, etc. Color grades. Clarity grades. Fluorescence.

Here's the chemical compound of most:



Hush and learn, boy.
