TREATMENT: Green Amethyst is produced by careful heating of Brazilian amethyst. The heat treatment of Amethyst between 878 and 1382 degrees F may produce light yellow, red
Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F).

On the other hand, many kinds of gemstones would not exist without heat treatment, e.g. tanzanite or prasiolith. Some gems are demanded at large amount in colors that they would not have if they were unheated. So in general, heating does not necessarily decrease the value of a colored stone, while it sometimes even increases its value.
a) Development of proper heat treatment technology and b) Development of furnace technology. Both technologies are taught in our training course in gem treating rubies-sapphires. More information in my books The Heat-Treatment of Ruby & Sapphire, Beryllium-Treated Rubies & Sapphires and Flux-Enhanced Rubies & Sapphires.

Heat Treatment. Centuries ago, someone stumbled upon the magical effect of applying heat to gemstones. High heat, such as that from a charcoal fire, can make a bland looking gemstone change its color into something spectacular. If this fortunate technique was not discovered, there would be very few affordable gemstones of good color on the market.
Alibaba.com offers 275 gem heat treatment products. About 23% of these are laboratory heating equipments, 5% are industrial furnace. A wide variety of gem heat treatment options are available to you, such as resistance furnace, induction furnace.
Heat treatment is a very risky process as many gems have inclusions that expand at a different rate and cause stress fractures, which then becomes an identifying characteristic of heated gems, particularly sapphire and ruby which can display halos around inclusions within the gem.
Heat treatment can be as simple as placing a specimen into a glass test-tube. Another simple technique is to place the specimen into the kitchen oven or bury it in the center of a charcoal brazier. To avoid fractures, heating process can be done at slower rate by burying the metal in some inert powder, for intance, iron filings and unburned
