Are You Purchasing Opal? Would you like to Know More about Opal?

GemSelect’s 100% Natural Opal is a great place to begin! Opal offers exceptional individuality within its three main classes; Precious Opal, Fire Opal, and Common Opal. The stone itself can display a remarkable amount of colors and effects that have delighted its viewers and wearers since ancient times. At GemSelect our Opal comes in a variety of forms like faceted stones, cabochons, beads, doublets, fancy cut sculptures, and beyond.

Why is Opal Often Cut Cabochon?

Opal is traditionally cut in a cabochon because the rounding and polishing of the stone can increase its natural beauty. It is a fact that some Opal is stunning with its intrinsic properties brought out by naturally cutting and polishing. However, some stones need a little more assistance to unlock their full potential like the Black Opal that often gets smoked, among others which undergo treatment to appear most divine.

How Do I Purchase Opal From GemSelect?

At GemSelect purchasing Opal is easy by shopping the category you’re in now you will have access to all types of opal varieties; including, Black Opal, Boulder Opal, Cat's Eye Opal, Chocolate Opal, Fire Opal, Moss Opal, Opal, Opal Doublet, and Opal in Matrix. You will also have the ease of shopping our Opal by Faceted Opal, Cabochon Opal, Single Loose Opal, Opal Pairs, and Opal Lots.

Many buyers look for a specific color or size when purchasing Opal. If this is the way you prefer to shop, we suggest you filter by base color: Blue, Brown, Green, Multicolor, Orange, Pink, White, and Yellow. After doing this, look for the piece you desire, or you can use another filter if our inventory is too vast.

If you have any questions or would like to contact us, please visit our ‘FAQ’ or ‘Contact GemSelect.’

What types of designs and Jewelry are suitable to make with Opal?

At GemSelect we recommend earrings, necklaces, pendants, opal rings, broaches and beyond. Opal is best rendered in the metal of your choice depending on the design of your jewelry and the color of your stone. The traditional favorites for mounting Opal include gold, white gold, silver, and rose gold. If you’re purchasing stones for a loved one’s October Birthday or a 14th Anniversary, you have come to the right place. The sentimental value of Birthstone gifts and traditionally accepted Anniversary stones will delight your loved ones and be cherished by them forever.


Opal can be drilled to make a pendant or earrings in addition to many other ways of 'Setting Opal.' Oversized Cabochons are great for 'pendants' and oversized cabochon rings. Men and women both wear Opal. The varieties which are famous for Men’s jewelry are Black Opal, Chocolate Opal, Boulder Opal and 'Opal in Matrix.' The varieties we suggest for women’s jewelry are Opal, Opal Doublet, Moss Opal, and Fire Opal.

What are Opal’s Color and Hardness Properties?

Opal ‘s hardness according to the Mohs Hardness Scale is 5.5-6.5 out of 10, so it should be cared for when wearing and designing jewelry with it. Multicolor Opal is sought after and can be extremely valuable depending on the specimen in question. The value of these stones is based on their properties of color, cut, and size. A beautiful Multicolor Opal can range from Opaque to Translucent and can change in its base hue to nearly any color imaginable. These complex combinations are what make the Opal so distinctive. Every Opal Gem can have a completely different set of characteristics and the ones that are unique, and large, are very rare and highly sought after.
