Shop 6x4 mm Calibrated Sapphires
Calibrated 6x4 mm sapphire is a practical choice when you need a loose gemstone that is close to a standard jewelry size. These stones are often selected for rings, earrings, pendants and replacement gems where millimeter dimensions matter.
Why Choose a Calibrated Size?
A calibrated gemstone is cut to fit common setting dimensions, helping simplify jewelry design and repair projects. While natural gemstones can have small measurement variations, starting with a 6x4 mm sapphire category makes it easier to find stones suited to existing mounts or planned designs.
Compare Color, Shape and Appearance
Sapphire is valued for its durable beauty and wide range of attractive colors. When shopping this category, compare each stone’s exact measurements, shape, face-up color, clarity and cut style to choose the best fit for your jewelry project.
Buying Loose Sapphire for Jewelry
Before ordering, confirm the required dimensions with your jeweler, especially if you are replacing a stone or using a pre-made setting. Review the individual product details and photos carefully, as each natural sapphire has its own character, proportions and visual appeal.

It was a good interaction I got a good gemstone for cheap
Overall Rating -> 10 
My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.

Very good place to buy gemstones

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
