Concave Cuts

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 love the variety of stones available, and especially that I'm not buying from a stock image -- the stone I see online is the actual one I'm getting.

So many stones, so little time and money. Easy to fill up the cart when the stones are beautifully pictured. I hope the real items are as beautiful.

Bought my first set of gemstones of gemselect to start off my collection. Everything is what it says it is, 100% legit. They even send u a pamphlet for every gem you order even the $1 ones lol. Good store.

I was looking for ammolite for my husband. Other websites are not always clear about whether they have genuine ammolite or simulated ammolite. I have purchased from GemSelect before and trust that the stones are genuine. Finding the stones I want is easy, and I love all of the search filter options!

After working with and polishing low-grade, rough fire-agate, only to be disappointed, this shop was nirvana. The costs of some gems might seem high, but I have easily spent the same amount rough polishing lousy material only to get a few hints of fire. If you want Fire-agates, BUY the agates you want. These are excellent specimens and are worth considering.

I have loved GemSelect for years; and have ordered many pretty and special gems for my personal use and for handmade gifts. Now I am going in a new direction and plan to design and build some lovelies for sale on the web.
