My last experience was good, in fact every experience I have had with them has met my expectations or surpassed them. These are really good people to work with.

I recently bought some stones for Christmas gifts for my family from GemSelect and was thrilled at the speed they arrived to me. The descriptions were accurate and could be verified by myself upon receiving the stones, though the only issue i had was finding exact stones i wanted. The sorting system is fanastically detailed, but often seems to trim more results than expected when i was selecting things to look by. They arrived safely and all together, as described per my purchase order and i could not be more satisfied. There aren't many that are looking to buy loose stones like this, but it really gets the job done.

Website is pretty easy to use. Some items do not have enough information like origin of the item or if they are natural or lab created. Not enough pictures/some pictures of products are not clear. This might possibly just be a mobile phone user problem however.

I like the search ability. I was looking for a gemstone of particular size and color to place in a ring that I already have. Your company carries a large variety of beautiful stones.
