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?

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?

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.

Are ruby stars rare?
