About Lab Created Sapphires
About Lab Created Sapphires-
A synthetic gem material is one that is made in a laboratory, but which shares virtually all chemical, optical, and physical characteristics of its natural mineral counterpart, though in some cases, namely synthetic turquoise and synthetic opal, additional compounds can be present.
Synthetic gem crystals have been manufactured since the late 1800s, and their production is often marked by a need for them in industrial applications outside of the jewelry industry. The first success was in producing synthetic ruby of faceting quality. Synthetic crystals are used in communications and laser technology, microelectronics, and abrasives. Because synthetics for jewelry applications can be “made to order” [i.e. consistent color and crystal shape] given the right ingredients, time, and the facilities to grow them, they are likely to be much less rare than natural gems of equal size, clarity, and saturation of color. Because of this, and because it is possible to confuse them with gems that are naturally occurring, there are strict guidelines regarding how they are marketed and sold.
Synthetic corundum the gemstone family which includes ruby and sapphire, can be made by the greatest number of processes. Because of this, synthetic corundum is available at many price levels, from very affordable to very expensive.
In melt processes, the chemical composition of melt is the same as the composition of the resulting crystal. In solution processes, the solution or melt has a different chemical composition than that of the resulting crystal. Constituents are dissolved in the solution or melt at high temperature, and the crystal forms initially on a seed crystal as the melt temperature is lowered
The color grading of lab grown sapphire gemstones is equal to that of naturally mined sapphires. This is because lab created sapphires stones are in essence, genuine sapphires!
The 3 keys to identifying a sapphire's color grade is; hue, tone and saturation. Color is graded by placing the sapphire face up on a white surface. The hue should be royal blue and the tone should be deep blue. The saturation should be even throughout the entire stone!
The best color for a blue sapphire is an intense deep royal blue. This color of sapphire would be considered AAA quality, the rarest and therefore the most valuable. The second best color is a medium rich blue, or AA quality. Any blue sapphires that have a gray undertone fit into the A category. If the sapphire has a very dark, opaque blue color, they are considered B grade. Our selection of lab created sapphire stones are AA-AAA quality.
