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 marquise shaped facet cut gems, gemstone carvings and cabochons available in 20 mm x 10 mm sizes. For the largest selection of colored gemstones, Shop GemSelect Online.
As a general guideline, when it comes to calibrated gems, they are not usually expected to be cut to exact measurements and specifications. But rather, they're cut with slight variance in size, though the close approximatation in size is not clearly defined, there are general guidelines for what is considered acceptable. Obviously larger and heavy carat weight stones allow more room in size for variance, while smaller stones may leave little to none. This means a large 30mm calibrated gemstone, could actually be closer to 31 millimeters. For this reason, we recommend to always view the exact size in addition to the calibrated size details. The exact size will inform you of the variance you can expect. Some setting styles are more flexible with variance, such as prong settings, while other styles of mountings may need almost an exact size to the fraction of millimeter.
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.

found what looks to be an incredible boulder opal on gemselect.com. Also got a bit carried away and bought more gems than anticipated. It's expensive to pay for these stones in this way, but the convenience makes it worthwhile.

I was looking for a tourmaline but although there were numerous beautiful stones to choose from, there was none that fit my need. Then I thought of some other beautiful stones I love and sunstone came to mind. I so thrilled when I was able to find the most gorgeous sunstone and with the exact specifications of my need. GemSelect makes it extremely easy to find the exact stone your looking for quickly and check out is just as easy to go through. I would (and have) definitely recommend GemSelect because of the large selection of stones, ease of use, and fast affordable shipping.

I’ve purchased from GemSelect a few times in the past year. I would not shop anywhere else. The photos make all the difference…I can select the exact color I want. I have over 100 pieces, and I’ve never been less than thrilled with each gemstone.

Gem Select is the source of moderately priced gems They should consider to have a section for outstanding gems to compete more directly with AJS gems.

I fell in love with my beautiful blue turquoise stone. When I received the stone it is more beautiful than the picture showed. I can hardly wait to design my pendant!)
