We strongly suggest that you read the Frequently Asked Questions. The questions are based on the real questions our customers ask every day. Most of your questions will be answered here.


How can you offer such cheap prices?

The answer to that is simple. We are buying at the source, top-quality rough straight from the miner’s hands. With state-of-the-art cutting and polishing, we believe that we deliver the best value for your money.

Does gemcal.com offer a printed gemstones catalog?

We do not offer a printed catalog because our stock changes every day, and all our gems are one-of-a-kind. We are constantly adding new items to our online store, and that makes it difficult to keep an up-to-date printed catalog.

Will there be any new items added to the web site? Or is this it?

We are adding new items on a daily basis. If you visited our site and did not find what you are looking for, contact our customer support team. We will do our best to supply you with your needs from our stock.

How accurate are your gemstone descriptions?

We do our best to accurately describe our gems. We can offer, on request, certificates from the local offices of the AIGS (Asian Institute of Gemological Sciences) or GRS (GemResearch Swisslab) in Bangkok .

How accurate are your pictures of gemstones?

We use state-of-the-art digital equipment to photograph our gemstones. Once the photo is taken, the image only goes through a compression process, without enhancements. No computer graphic programs are in use to modify or enhance the pictures in any way. We do our best to accurately depict the colors of the products on this site. However, because the color you see is dependent on your computer monitor, we cannot guarantee that the color you see will be identical to any other screen. The products also may appear larger or smaller than their actual size depending on your monitor.


If you have any treated stones, are they marked as such?

All our gemstones are natural. We do not sell synthetics or imitation stones. All of the gemstones offered on this website follow the American Gem Trade Association guidelines regarding gemstone enhancements . Failure to identify enhancement of natural gemstones, when present, is an unethical trade practice! The only colored gemstone enhancement processes that are considered acceptable are those that add nothing artificial to the gem or that imitate a natural process and is permanent.
