Facts about Untreated Rubies | No Heat Rubies
Let’s explore key facts about about untreated ruby gemstones:
  • Extreme rarity: Untreated rubies are exceptionally rare, with less than 1% of rubies on the market being completely natural and untreated. This rarity significantly increases their value and desirability among collectors and gemstone enthusiasts.
  • Inclusions as proof of authenticity: Natural, untreated rubies often contain inclusions, which are actually considered valuable in determining their authenticity. These small imperfections can enhance the gem's appearance by giving it a velvety look and are a key indicator that the ruby has not undergone treatment.
  • Fluorescence in sunlight: Untreated rubies, particularly those from Burma (Myanmar), exhibit strong fluorescence under ultraviolet light or even in natural sunlight. This unique property causes them to appear to glow from within, adding to their allure and mystique.
  • Superior value: Due to their rarity and natural beauty, untreated rubies are extremely valuable and can command prices that surpass even the finest diamonds. Their unenhanced state makes them highly sought after by collectors and investors.
  • Pigeon's blood color: The most coveted untreated rubies display a deep red hue known as "pigeon's blood," which is considered the pinnacle of ruby coloration.
  • Asterism in some specimens: Some untreated rubies may exhibit asterism, a rare star-like pattern caused by mineral inclusions. These "star rubies" are even more valuable than their non-asteriated counterparts and are highly prized by collectors.
  • Historical significance: Untreated rubies have been prized for centuries, with many cultures attributing mystical properties to them. Their natural state connects them to ancient traditions and beliefs surrounding the gemstone.
  • Challenging identification: Distinguishing between treated and untreated rubies can be difficult, often requiring advanced gemological testing. This makes untreated rubies even more valuable, as their authenticity must be carefully verified by experts.
