Calibrated 13 x 13 mm Trillion Shape Loose Natural Gemstones from GemSelect

Trillion Shape 13x13 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 Trillion shapes, facet cut and cabochon gems available now in 13 mm x 13 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 meant nor 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 like to use GemSelect for finding calibrated sizes of gemstones. I purchased sapphires a few years ago and found the quality to be outstanding so I went ahead and purchased some more today (different) and some really unique moonstone. I'm opening a jewelry busy soon and so accurate gemstone sizes, quality, and reliability as a supplier is really important to me. Gemselect seems to fill all those requirements.

I've been collecting gemstones for a while now so I wad excited that I found a relatively cheap site to gems from. When I opened to package i was a little surprised and how small they were but it's literally marketed for jeweler's so I understand why my little square cut sapphire is the size of a crumb, but all in a ll I'm very happy with what I ordered.

I was very happy with the simplicity and prices of gemselect.com. the sites filters and navigation style made it simple to find exactly what I was looking for. I will definitely be buying from gemselect ago. Compared to other online stone sellers, the prices and availability of gemselect was amazing.

So many stones, so little time and money. Easy to fill up the cart when the stones are beautifully pictured. I hope the real items are as beautiful.

Website is pretty easy to use. Some items do not have enough information like origin of the item or if they are natural or lab created. Not enough pictures/some pictures of products are not clear. This might possibly just be a mobile phone user problem however.

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.
