In the precious stones trade, the gemological laboratory plays an increasingly important role. The reputable merchant wants to be sure he correctly describes his items, and many buyers want to be assured of an identification report from a respected gemology laboratory. Gemstones labs help keep the gem industry honest, as buyers and sellers know that gemstones are subject to possible testing at any time.

Here in Chanthaburi, Thailand, a local gemological laboratory university is exploiting the rights to the gemstone market. With gemologists trained at the famous Asian Institute of Gemological Sciences (AIGS) in Bangkok, they can test gems in a few hours so that offers can be closed quickly.

Currently many well-equipped laboratories are doing basic gem identification tests quickly and inexpensively. But the jewelery treatment test can take longer and have higher costs.

An issue for gemstone testing companies is how to maintain consistency between labs and in the way gemstones are described. If a laboratory describes a stone as "Tourmaline elbait copper" and another laboratory describes the same stone as a "Tourmaline Paraiba", the certificate indicating "Paraiba Tourmaline" may very well give the owner of this stone an advantage in the market.

To this end, some of the most respected gemological laboratories in the world have created an organization called Laboratories Harmonization Committee (LMHC), whose purpose is to standardize the formulation of reports as well as certain methods of analysis and results interpretation. The lab created gemstones for sale.

Swiss Blue Topaz Description:

Magnificent Swiss blue topaz entirely faceted with a very good quality. The stone is natural and despite its name does not come from Switzerland. However, the name Swiss Blue Topaz or commonly called Blue Swiss Topaz is a stone that has undergone several treatments.

In fact, the first treatment is the irradiation of the stone which makes it possible to transform the natural color of an often clear stone by another color. The second treatment is the heating of the stone which makes it possible to accentuate the color obtained by the irradiation. These methods are always used when you buy a natural Swiss blue topaz with this particular name no matter where you buy it. Information, transparency and the law obliges all stone traders to report such treatments on stones regardless of form or origin.

You can buy lab created gemstones from online stores, as well as from jewelers also.
