Loved the price and the quality and the certification options which is the main reason why I buy. The guarantee is also a great reason to use gem select.

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.

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.

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.
