What are loose untreated gemstones?

Loose untreated gemstones are natural stones that have not undergone any artificial treatments or enhancements. Examples include unheated sapphires, untreated rubies, and unenhanced diamonds, which maintain their natural beauty and originality.

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.

Are untreated gemstones more expensive than treated ones?

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.

Overall Rating -> 10 star ratings

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.

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.

I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring

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.
