2.78 ct Red (Pigeon Blood) Ruby – Cushion Cut – Heated – Mozambique

This 2.78 ct natural ruby presents a vibrant red color with strong visual intensity, paired with a refined cushion cut that enhances brilliance and delivers an attractive face-up appearance. Originating from Mozambique, one of the world’s most important modern ruby sources, the stone displays a rich, saturated tone characteristic of fine Mozambican material.

According to the AIGS gemstone identification report, the ruby shows indications of heat treatment (TE1, C1)—a common and accepted enhancement in the trade used to improve color and clarity. The stone has been graded “Pigeon Blood” on the AIGS Ruby Color Grading Scale, reflecting its vivid red coloration within AIGS’s proprietary grading system.

The ruby exhibits lively internal character, good transparency, and balanced proportions, making it well suited for fine jewelry applications or collectors seeking visually striking ruby material with documented origin and laboratory certification.

Every gemstone offered by Sora Gems is professionally inspected inside Bangkok’s Jewelry Trade Center (JTC) to verify authenticity, treatment classification, and overall quality before being approved for sale.

To preserve the beauty and longevity of your gemstone, we recommend gentle care. Clean the stone using warm soapy water and a soft brush, avoiding harsh chemicals or ultrasonic cleaners unless the gem type is known to be safe for those methods. Store your jewelry separately in a soft pouch or box to prevent scratches from harder materials. Always remove gemstone jewelry during vigorous activities—such as exercising, swimming, or using household cleaners—to protect it from impact, heat, and chemical exposure. Regular professional inspections are encouraged to ensure settings remain secure and the stone stays in optimal condition.
