Concave cutting involves cutting facets that are three dimensional (curved). The technology to cut concave facets was developed by the American inventor Douglas Hoffman around 1990. It allows conical-shaped, three dimensional facets to be cut, so that each facet has depth as well as length and breadth. The result is that more of the ambient light is refracted and returned to the eye in the form of brilliance.

In order to find the concave-cut gems that you require, filter the results further by using the left-hand menu. You can buy concave-cut gems by gem type, color and shape. By using the top menu, you can search by carat weight, size, price, origin and other factors, to enable you to find the exact concave-cut gems that you are looking for. All items are in stock and ready to be shipped.

I really enjoy browsing through GemSelect. The selection is always marvelous and I love how detailed everything is described. The only thing I noticed is that when browsing through my phone, the videos of the gems do not load. If there were more videos of the gems, that would be amazing, though I understand that is a lot of work on GemSelect's part! Checking out is also very fast and easy, and I love that the return policy is very good, though I hope I don't have to use it anytime soon.

Everthing about researching and ordering from Gemselect was easy and uncomplicated. In the past I had payment problems, but your customer rep, Thomas, helped me get everything right. I will continue using Gemselet in the future for these reasons.

The website design is a bit finicky for mobile, but Im sure its most likely just a mobile issue. Amazing selection of products, great prices.
