5.37 ct Red (Pigeon Blood) Ruby – Oval Cut – Heated – Madagascar

This 5.37 ct natural ruby showcases a vivid to deep red color with strong saturation, paired with an elegant oval modified brilliant cut that enhances brilliance and delivers a commanding face-up presence. Sourced from Madagascar, a highly regarded origin for fine ruby production, the stone exhibits the rich color and visual depth prized by collectors and high-end jewelry designers.

According to the Guild Gemological Report, the ruby shows indication of thermal enhancement with minute residues (H[1]), a permanent and widely accepted treatment within the trade that is commonly used to refine color and clarity while preserving the stone’s natural crystal structure. The report further assigns the trade name “Pigeon’s Blood”, reflecting its vivid red coloration within Guild’s grading standards.

The ruby displays lively internal character, attractive transparency, and well-balanced proportions, resulting in a bold yet refined appearance. Its size, color presence, and documented origin make it an excellent choice for high-end jewelry creations, collectors seeking substantial ruby material, or buyers focused on visually impactful certified gemstones.

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.
