Octagon Shape 25x18 mm Gems

Some people by gems by color or price, but for many, it is best to buy gems by shape and size - especially if you're in need of a gem to replace a previous item that was lost or damaged. Calibrated Octagon shape / Emerald-Cut, faceted and cabochon gems available now in 25 x 18 mm size range. Shop a wide range of calibrated gemstones by size online at wholesale from GemSelect.

As a general guideline, when it comes to 'calibrated' gems, they are not usually expected to be cut to exact measurements. For calibrated gemstones weighing under one carat, most jewelry settings will accommodate a gem which is within 0.2 mm of the calibrated size in order to fit a standard setting. For gemstones that weigh over one carat, a larger variance is acceptable, often round shape settings will allow 0.3 mm or slightly higher even. This small variance can usually be accommodated for most standard style settings. Round-cut gemstones should also have a greater variance in acceptable size when it comes to calibration; in fact it is usually possible to mount a round stone of any size in the closest standard setting.

Everything was good about this order except I was a little disappointed in the product because it was so small. This is the first time that I have ever bought a gem so I was very unfamiliar with the sizes mainly because measurements were in metric.

This site is *amazing*! The vast selection is almost enough to make you giggle. Oh, wait…If you want it, it’s probably here. I’ve read some reviews saying it’s hard to use the search filters but I found the opposite to be true. In fact, it’s plain fun to throw different filters on and see what you come up with. I ordered a small stone to sort of try them out and, dang! I’m so thoroughly impressed that I think I found a new hobby. The stone I got was exact what was represented on the site. So much so that I had to really look to see the difference between the picture and the stone that I got. And the range of prices. Wow! From a few dollars to tens of thousands if you’re into like, Ruby’s, Emerald’s, Sapphire’s and other gems that make you drool. And the cuts! The shapes and cuts are just plain gorgeous!Honestly, I can’t possibly say just how happy I am with this purchase! Now… off to make another…

Gem select was a company we were just looking at their products and my wife liked her birthstone so we ordered it and when it came she was very happy with what she received and because of that she wants to order again to make earrings with the next order so Gem Select is the company we will be shopping from now on

Exact dimensions of each gem would be helpful, or even better, place the gem on a white paper with 1 mm black grid so that exact dimensions can be see. Otherwise great experience! I hope your business prospers!!

I think the GemSelect website is exceptional. It gives me comfort and confidence that what I select is what I will receive from them. This is why I buy from them. I've purchased many gems from them online and have never been dissatisfied. I like the paperwork that ships with the orders and the reports that are available.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
