Natural Black Opal Gemstones
Natural black opal gemstones are valued for their dark body color, which enhances vivid flashes of red, blue, and green play-of-color. These rare opals are among the most sought-after varieties in the world.
Loose Black Opals for Jewelry
Loose black opals are ideal for custom jewelry designs, allowing jewelers to showcase each stone’s unique color patterns. They are especially popular for rings, pendants, and statement pieces.
Australian Black Opal
Most fine black opals originate from Australia, particularly Lightning Ridge. Australian black opal is renowned for its strong color contrast, durability, and consistent quality.
Black Opal Play-of-Color
The defining feature of black opal is its intense play-of-color, created by light interacting with microscopic silica spheres. Darker body tones make these colors appear brighter and more dynamic.
Black Opal Cuts and Shapes
Black opals are commonly cut as cabochons to maximize color display, though select stones may be faceted. Popular shapes include oval, freeform, and pear.
Investment-Grade Black Opals
High-quality black opals with strong brightness and rare color combinations are often purchased by collectors as long-term investments due to their limited supply.

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

The purchasing process is fairly quick and straightforward and for me user friendly so it probably took more or less than 3 minutes to purchase and pay for the items. I wish there was a discount offer for multiple items to encourage us buyers to purchase more an incentive and add more sales in your end. Besides that, it's been a great purchasing experience and will continue to shop as I am a repeat customer and have bought from your store many times before. Thank you.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
