    Diamonds are a crystalline form of carbon, and so making artificial carbon crystal was the problem of lab grown diamonds. For decades, manufacturers of synthetic gemstones tried growing diamonds like they grew rubies, sapphires, and emeralds. It failed. Then they had the idea to grow diamonds in the lab like they grew in nature. Other articles where Synthetic gem is discussed: emerald: long made to manufacture it synthetically. These efforts finally met with success between and , when a German patent was issued to cover its synthesis. Synthetic emeralds are currently manufactured in the United States by either a molten-flux process or a hydrothermal method; in the latter technique, aquamarine crystals.

Many of these gemstones have the exact chemical composition of the same stone created in nature (e.g. Charles & Colvard Moissanites), so technically, they are still the real deal.

Manmade gemstone imitators can be classified as simulants or synthetics. A simulant looks like and may be used in place of a gemstone but does not share any of the chemical or physical properties with that gemstone.

Conversely, a synthetic is a manmade gemstone with the same appearance, chemical formula, and crystallographic structure as the natural gemstone it is imitating. Commercial productions of synthetic alexandrite. Most synthetic alexandrite is manufactured in the Russia, Japan, and the USA. Synthetic alexandrite gemstones were first produced in by Creative Crystals of San Ramon California.

Virgil E. Bottom High Meadows Dr. Abilene, Texas With the aid of many of the people who were involved, this paper is an attempt to record the history of the quartz crystal industry in the USA.

Although crystal units were in use at least a decade earlier, the beginning of the quartz crystal industry in the USA. To produce a gem-quality synthetic diamond, a diamond seed crystal (natural, HPHT, or CVD in origin) is introduced into the gas mixture, at an elevated temperature of to °C.

The activated carbon-hydrogen species travels across the surface of the diamond seed until it finds an available carbon atom, and then attaches itself to this seed. Synthetic diamonds are made at about deg C, but usually in a pressure vessel using microwave radiation and a "seeding" crystal.

You can make diamond as big or small as you want by growing them in a chemically neutral environment (nobel gas/ nitrogen) using CO2.

A lattice system is a class of lattices with the same set of lattice point groups, which are subgroups of the arithmetic crystal 14 Bravais lattices are grouped into seven lattice systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic.

In a crystal system, a set of point groups and their corresponding space groups are assigned to a lattice system. Founded inCarat Systems provides sophisticated diamond deposition systems for industry and gem markets.
