Mexican Opals
More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied a folklore. Opals are also the most delicate gems commonly worn. They require special care to ensure their health and longevity.

Opal's fire was long thought to be the result of iridescence. However, with the advent of scanning electron microscopes, we now know that it is a result of diffraction.

Opal is relatively soft, with a rating of 5.5-6.5 on the Mohs scale. Despite its frequent use in rings, opal is a poor choice for a ring stone; it is much better suited to earrings, pins, and pendants.

Major suppliers include Australia, Brazil, Mexico, and the US. Values are normally determined by the presence and nature of color flashes.

Shop for Mexican opal gemstones in a variety of calibrated sizes, cuts and colors, including white, yellow, orange and red fire opal gems.

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.

I would recommend to a friend because of the quality of the products purchased. The gemstone quality is very high and the gems purchased are beautiful. 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
