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.

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.
