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 6 mm x 3 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.

I was just browsing on my trusted gem site, Gem Select, when I saw gems that were my grand children's birth stones. The price was right, so I ordered them. I like to surprise my grand children with something special for their birthday, and they will be nice birthday gifts.

It's important to understand what you are buying. Gem stones all vary significantly and you need to adjust your selection based on purpose, cost, expected out come.In my case I was selecting and very attractive heart shaped stone which once set in a pendent would fall in a specific cost range yet present an attractive picture of luxury without extreme risk e.g loss.

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!!!!
