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 Round shapes, facet cut and cabochon gems available now in 12 mm diameter 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 around 0.3 mm or slightly higher even. This small variance can usually be accommodated for 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.

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.

The items I ordered were exactly as described on the website. Delivery took a little longer than I had hoped, but they were delayed by a holiday. On arrival, I inspected the items and am very pleased with the quality. I will certainly be sourcing other product from Gem Select.

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!!

It was a nice and easy process throughout! The website is simple and well made I found everything I needed quickly. I needed some emeralds of a certain size for my custom engagement ring but they only had 3 available on the website, So bought the available ones and reached put to customer service to see if they have any more and they messaged me back within minutes with a list of similar sized emeralds that were not on the site! I quickly purchased my remaining emerald and they added it to my first order! I am more than pleased with the experience and I will be recommending them to anyone in the market for gems! 10/10

This business makes it easy to research and find all pertinent information about the individual gemstones and other information such as the recommend use (ring or pendent for example). Also it's important to know about things like hardness and durability of the gemstones. I also appreciate the history of purchases and transaction details. Just be sure to register on the website to get the best experience.

I enjoy wearing jewelry, so I choose the stones from gem select, then take the gem to a jeweler and get the item made.
