What makes a loose star ruby unique?

A loose star ruby is renowned for its captivating asterism, the star-like phenomenon visible on its surface. This unique effect makes it highly prized among gemstone collectors and jewelry enthusiasts alike.

How does the star effect appear on star rubies?

The star ruby showcases an asterism effect due to light reflecting off inclusions within the gem. Most commonly, this results in a 6-ray star ruby, which is enhanced by cutting the gem into a cabochon shape.

What are unheated star rubies?

Unheated star rubies are gemstones that have not undergone any heat treatment, preserving their natural beauty. These gems are especially sought after by collectors who value their authenticity and natural formation.

Are Burmese star rubies considered the best?

Yes, Burmese star rubies are highly esteemed for their exceptional quality, vivid red hues, and distinct star effect. They are among the most valuable types of star rubies on the market.

Why should I buy loose star rubies instead of pre-set ones?

Purchasing a loose star ruby allows for greater customization. Whether you're designing a custom piece of jewelry or adding to your collection, star ruby loose gems offer flexibility and the opportunity to inspect the quality and appearance firsthand.

What are asterism gemstones?

Asterism gemstones are stones that display a star-like effect due to light reflection. The star ruby is one of the most popular examples, admired for its radiant stars and vibrant color.

Who are loose star rubies suitable for?

How can I identify a natural star ruby?

A natural star ruby will exhibit its star effect naturally under direct light without synthetic enhancements. Look for certifications to ensure you’re purchasing an authentic gem.

Are ruby stars rare?

Yes, ruby stars are relatively rare due to the specific conditions required for asterism to occur. This rarity contributes to their desirability and value among gem enthusiasts.

What settings work best for loose star ruby jewelry?

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.

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.
