Are untreated gemstones suitable for engagement rings?

Yes, untreated gemstones like GIA-certified natural gems, unenhanced diamonds, and untreated rubies are excellent choices for engagement rings. They offer timeless elegance and are ideal for creating one-of-a-kind designs that reflect personal style.

What makes rare untreated gems valuable for collectors?

Rare untreated gems for collectors, such as authentic untreated crystals and unheated and untreated stones, are prized for their natural appearance and limited availability. Their untouched state makes them highly desirable and a great investment.

How can I ensure the quality of loose untreated gemstones?

Always choose certified untreated gems, like GIA-certified natural gems, to guarantee authenticity and quality. These stones undergo thorough evaluation to ensure they meet the highest standards, making them ideal for both personal collections and jewelry projects.

What types of untreated gemstones are available?

Our collection includes a variety of untreated gemstones such as unheated sapphires, untreated rubies, unenhanced diamonds, and unheated topaz. Each stone is carefully selected to offer unmatched quality and natural beauty.

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.

the gems were smaller than I thought but I was at fault for not reading the complete discrimination

Overall Rating -> 10 star ratings

I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.
