Quartz Cabochons
Quartz is one of the most common minerals on earth, and is well known in the gems world in its many forms - amethyst, citrine, ametrine, smoky quartz, rose quartz and lemon quartz. Quartz is attractive and durable, as well as inexpensive. It can be cut and carved in many forms and sizes.

There are 2 main varieties of quartz, including both crystalline and cryptocrystalline quartz. Crystalline quartz occurs in distinct transparent crystals, such as in amethyst and citrine. In cryptocrystalline quartz, the crystals are microscopic and the quartz is opaque or translucent. Examples include chalcedony and agate.

Shop from a wide variety of quartz gemstones of almost all colors of the rainbow. Choose cabochon quartz gems, including calibrated sized single gems, matched pairs and gem lots by using the tick boxes at the top of the page. All photos are of actual gemstones that are available and ready to ship.

I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.

Any friends interested in having custom jewelry made would definitely be recommended to the site. Also, every shipment is handled with care and I am very pleased with that.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
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

Note: 1ct = 0.2g
