In many cases, untreated gemstones, like precious untreated gemstones and virgin untreated stones, can be more valuable due to their rarity and natural state. Their unique characteristics make them highly sought after by collectors and jewelry enthusiasts.

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways

I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.
