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.

Pleased to finally find nice amethyst cabochon that I can afford. I am designing pendant for friend in silver.
When buying high-price items - like gems - it can be scary you are being scammed. GemSelect has no hidden strings. I tested this by purchasing very small, but they have won me over. Their prices are upfront and the quality is as expected. They also package their gems well, and ship incredibly quickly. Their website is easy to use, and they have quick customer service. Best eWholesaler.
I was looking for very specific loose gems for my collection and some loose gems to add to a piece of jewelry I want to have made and Gem Select had everything I was looking for and the selection and price ranges were outstanding. I will absolutely purchase from this vendor again and often. I am so very pleased with the items I received.
I checked reviews throughout the internet and was thoroughly impressed with the positive experiences of others. I’m constantly worried about purchasing fake stones. The many satisfied customers have given me confidence in what I’m purchasing.
