The octagon or emerald-cut is a shape that was developed to maximize the color of emerald gemstones. Therefore, if you are looking for a gem that shows pure, unadulterated color at its best, emerald cut gems are the right choice. The octagon-cut showcases the color of a gemstone.

Octagonal colored gemstones from GemSelect include large stones, matched pairs and lots. Among the choices are both precious and semi-precious octagonal gems, for example, bicolored ametrine, tourmaline, emerald, amethyst, smoky quartz, diamond, topaz, tanzanite and tsavorite garnet. There are emerald-cut gemstones of every color, size, shape and cutting style available. Some emerald-cut gems are square and others are long and rectangular.

To find the octagonal gemstones that you seek, filter the results further by using the left-hand menu. You can buy emerald-cut stones by gem type or color. By using the top menu, you can search by carat weight, size, price and other factors, to enable you to find the exact emerald-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.

The website is well organized and works fast forward and back. Plenty of filters. Each gem is described in detail and you receive the one pictured. Gem material info and sources available. I would like to see more specifics on sources besides country- at least region or state and in the US with Turquiose which mine. Thanks!
