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.

The website design is a bit finicky for mobile, but Im sure its most likely just a mobile issue. Amazing selection of products, great prices.

I really enjoy browsing through GemSelect. The selection is always marvelous and I love how detailed everything is described. The only thing I noticed is that when browsing through my phone, the videos of the gems do not load. If there were more videos of the gems, that would be amazing, though I understand that is a lot of work on GemSelect's part! Checking out is also very fast and easy, and I love that the return policy is very good, though I hope I don't have to use it anytime soon.
