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 had a great time searching all the lovely stones. This is my first precious loose stone purchase for my own work. I chose sapphire, and found some lovely briolettes. I wanted 3, but this set of 4 was perfect. Everything was quick and easy, and I'm excited.

The website is user friendly, has excellent selection. I've always found what I was looking for with Gem Select. When others don't have it they do. And most important, they have a way for you to pay without using PayPal. I cannot use PayPal they closed my account because of no cell phone.
