Market Price Range

Commercial grade: $100 - $500 per carat; Fine quality: $1,000 - $15,000 per carat; Top quality (e.g., "Pigeon's Blood"): $20,000 - $150,000+ per carat

Detailed Description

Ruby is the collective name for red corundum, with its color primarily derived from trace amounts of chromium. The color ranges from pink to deep red, with "Pigeon's Blood" being the highest grade, characterized by its intense, pure hue and exceptional value. Historically, ruby has been associated with royalty and divine power, mentioned multiple times in the Bible and used as a talisman by ancient warriors. When collecting rubies, it is essential to consider the "4Cs" (color, clarity, cut, carat weight) and origin. Rubies from Mogok, Myanmar, are renowned for their exceptional quality. Furthermore, whether the stone has been heat-treated is a critical factor affecting its price; untreated natural rubies are rarer and more valuable. For investment and collection purposes, it is advisable to choose gems with certificates from internationally recognized authorities like GIA or SSEF to ensure their quality and value.

Identification Methods

Color Observation: Natural rubies often have uneven color distribution and growth textures, whereas synthetics appear too uniform.

Internal Inclusions: Under 10x magnification, natural rubies frequently contain silk-like, acicular "silk" inclusions or fingerprint-like healed fractures.

Fluorescence Reaction: Under long-wave UV light, natural rubies typically exhibit moderate to strong red fluorescence, while some synthetics or treated stones may react differently.

Pleochroism: Viewing from different angles reveals pleochroism of red and orangey-red, a typical characteristic of corundum.

Professional Certification: For high-value rubies, it is recommended to submit them to a reputable gemological laboratory (e.g., GIA) for precise origin and treatment information.

Market Information

The ruby market remains robust, especially for high-quality, unheated natural rubies. Mogok in Myanmar and Mozambique are the primary sources for top-tier rubies, with their "Pigeon's Blood" variety being highly sought after, frequently setting new price records. As demand from emerging markets grows and resources become scarcer, the investment value and collection potential of rubies continue to increase. Consumers should focus on factors like color, clarity, carat weight, and origin when purchasing.
