FAQs

What makes a loose ruby valuable?

A loose ruby is valued based on its ruby color, gemstone clarity, and carat weight. Rare varieties like pigeon blood ruby and Burmese ruby are especially prized for their vivid red hues and minimal inclusions.

What is the difference between a faceted ruby and a ruby cabochon?

A faceted ruby is cut with multiple flat surfaces to maximize brilliance, while a ruby cabochon has a smooth, rounded shape, showcasing the stone’s natural beauty. Both types are popular in ruby jewelry designs.

How do ruby inclusions affect value?

Most natural rubies have some level of ruby inclusions. While minor inclusions are common, fewer inclusions generally increase a ruby’s value, as they enhance the stone’s gemstone clarity.

What is a star ruby, and why is it unique?

A star ruby is a rare type of loose ruby that displays a star-like pattern across its surface due to light reflecting off its inclusions. These are highly sought after for their distinct appearance.

How can I tell if a ruby has been heat-treated?

Heat-treated rubies are enhanced to improve their ruby color and clarity. A gemologist can help identify whether a loose ruby has undergone treatment by examining the stone’s internal characteristics.

Are Burmese rubies more valuable than other rubies?

Burmese rubies are among the most valuable due to their deep red color and excellent gemstone clarity. Their origin in Myanmar (Burma) is historically associated with some of the finest loose rubies in the world.

What is the best setting for loose rubies in jewelry?

Settings for loose rubies depend on the stone’s cut. A faceted ruby may be showcased in a prong setting to maximize its brilliance, while a ruby cabochon can be beautifully displayed in a bezel setting for protection and style.

What are loose rubies?

Loose rubies are unmounted gemstones that are not set in any jewelry. They offer flexibility for creating custom designs such as rings, necklaces, and earrings. Our collection includes a wide range of loose rubies, including natural rubies, certified rubies, and untreated rubies.

What is the difference between heat-treated rubies and untreated rubies?

Heat-treated rubies undergo a process to enhance their color and clarity, making them more vibrant and appealing. Untreated rubies, on the other hand, retain their natural properties and are prized for their originality and rarity. Both types are available in various shapes, such as oval ruby, round ruby, cushion ruby, and emerald-cut ruby.

What is a pigeon blood red ruby?

Pigeon blood red rubies are highly sought-after gemstones known for their vivid, deep red hue. They are often considered the finest rubies and are commonly sourced from regions like Burma (Myanmar) and Mozambique.

What is corundum, and how does it relate to rubies?

Rubies belong to the corundum mineral family, which is known for its exceptional hardness and durability. With a rating of 9 on the Mohs scale, rubies are ideal for everyday wear and are one of the hardest gemstones in the world.

Can I use loose rubies for custom jewelry?

How do I choose the best loose ruby?

GemSelect Certified Store Reviews

GemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!

Overall Rating -> 10 star ratings

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.
