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.

Completely would recommend this company to any gem collector, jewelry store, or someone looking for a gemstone to repair their jewelry. There is an abundance of choices at great prices! If you don’t see what you need exactly the customer service department will go above and beyond to meet your needs. Shipping is very reasonable! The gemstones always arrive well before the expected arrival date. This company has very high standards of meeting their customers needs! They are the number 1 company I go to when looking for any gemstone. They are also very detailed in their descriptions so there is no confusion at all as what you are purchasing! Highly recommended!!!!

I love looking at gems. Your site is very easy to navigate and to find what I'm looking for. It is also very easy to explore lesser-known gems that are not always easily found. I spend way too much time exploring! LOL

gem selection is pretty great, prices are unbelievably low, however the cut of some gems is questionable at best. you have to dig for the good ones, but it’s worth it for the price

I have been looking at the website for a few days, educating myself about Sapphires and other gems. I want to have earrings made as a gift for someone. I bought a air of gemstones for myself today. They look beautiful in the photo.

I have found what I think is the best kept secret for buying stones, and I have to tell you about this gem stone site I found! There is a large selection of stones and crystals, and the best prices I have found for nuummite! They make it incredibly easy to find exactly what you are looking for by shape, size, cost, and clarity. I have already purchased two stones and I will be checking the site frequently from now on for everything and anything that I am hoping to find. They have individual pictures of every stone with different views so you absolutely know what you are buying.Honestly, I was hesitant to purchase something the first time BECAUSE the prices were so competitive and below anything I found elsewhere and because the stone was both being purchased online and from another country. I received the stone ahead of shipping schedule and when I received the package, it was in not one but two separate zip lock bags. One had the certificate of authenticity and details about the stone. The second had information about the stone itself. I was so impressed with the quality of the stone and that it was definitely the stone I picked out on their site, that I ordered another stone without hesitation. I will be using this site to purchase gifts for everyone I can think of! lol

I have purchased several times from GemSelect and am always pleased with the stones. The information on the site about each stone is thorough. I don't have to worry about fake stones from them and the prices are quite reasonable. I love the new cards provided for each stone. I would highly recommend them.

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
