What makes Australian black opals unique?

I've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.

Why Choose Loose Black Opals?

Loose black opals are prized for their unique play-of-color and deep, dark body tones. From Australian black opals to Ethiopian black opals, these gemstones are versatile and perfect for creating custom jewelry pieces. Whether you're looking for a solid black opal or a semi-black opal, their natural beauty and rarity make them a top choice for gem enthusiasts and designers alike.

Understanding the Different Types of Black Opals

The most sought-after black opal gems include natural black opals, solid black opals, and semi-black opals.

For collectors, options like uncut black opals and raw black opals offer an unpolished glimpse into nature's artistry.
