Why should I choose untreated gemstones over treated ones?

Untreated gemstones, such as unheated topaz and virgin untreated stones, are valued for their authenticity and rarity. These certified untreated gems are perfect for collectors and those seeking ethically sourced, natural stones for unique jewelry designs.

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.

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.
