Marquise Shape 6x3 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 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.

Purchase process is easy. Make the selection online and pay for it. About a week to 10 days later the stone shows up. Very easy and on time.

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.

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.

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
