- Professional Service and Support
Our buyers and gemologists are leaders in their fields. We buy rough gemstones at the source and process our own material. With a wealth of experience, our buyers, gemologists, cutters, and graders, inspect every stone to minimize the risk of misidentification.
All Multicolour gems are natural. We make every effort to insure the accuracy of our descriptions. While we do photograph with favorable lighting conditions, we do not enhance or alter the colors of our images at all. We do not sell synthetic or lab created stones.

- Gemology and Third Party Certification
Gemstones are unique creations of nature and do not always submit themselves easily to identification or classification by gemologists. In some cases even gemological laboratories cannot agree regarding the treatment, the origin, or even the final classification of a particular gemstone.
When does a chrysoberyl show enough color change to be called an alexandrite? When is a pink or a purple sapphire considered to be red enough to be termed a ruby? When does a pink and orange sapphire contain the right percentage of each color to be called a padparadscha?
Sapphires and rubies are generally enhanced by heat unless otherwise specified. This is a recognized industry practice and serves to enhance their existing natural beauty.
These decisions are subjective rather than objective, they depend on the judgment of the beholder. In borderline cases, we make every effort to provide detailed descriptions.
Here in Bangkok, gemstone identification certificates are available from AIGS (Asian Institute of Gemological Sciences), Tokyo Gem Lab, or from the GIT (Gem and Jewelry Institute of Thailand).
USD 15.00 / Mini identification report
USD 30.00 / Full report with a photograph
Certificates from GIA, AGL, (U.S.A.) or, SSEF (Switzerland), can also be arranged.
- Treatments and Disclosure
Stones like aquamarine, amethyst, tourmaline, and tanzanite may also be heated to improve their color. Emeralds are often oiled and this practice is also generally accepted in the trade provided that the oil used is almost colorless and not green. Treatments are disclosed in our stone descriptions except in cases where the information is unavailable.
PLEASE NOTE THAT WE DO NOT ENHANCE OR ALTER THE COLORS OF OUR IMAGES AT ALL. WE DO NOT SELL SYNTHETIC OR LAB CREATED STONES
SOME GEMSTONES ARE ROUTINELY ENHANCED AND THE TREATMENT IS ACCEPTED IN THE TRADE. PLEASE READ OUR STONE DESCRIPTIONS FOR A DETAILED DISCLOSURE IN CASE OF ANY ENHANCEMENTS OR REFER TO ACCEPTED GEMSTONE ENHANCEMENTS SANCTIONED BY THE GEMSTONE INDUSTRY AT GEMSTONE ENHANCEMENT GUIDE AND GEMSTONE ENHANCEMENT CODES AND DEFINITIONS FOR MORE INFORMATION.
