4.02 ct Pinkish-Red (Pigeon Blood) Ruby – Heart Cut – Untreated – Mozambique

This 4.02 ct natural ruby features an attractive pinkish red hue with lively saturation, fashioned in a distinctive heart shape that offers strong visual appeal and a charming face-up presence. Originating from Mozambique—one of the world’s most important modern ruby sources—the stone reflects the region’s reputation for producing vibrant, well-saturated material.

According to the AIGS Gemstone Identification Report, there is no indication of heat treatment (NTE), and no other enhancement is reported. Under AIGS terminology, this confirms the ruby is untreated, meaning it has not undergone heat or any other disclosed enhancement—a significantly rarer classification than unheated stones alone and one that can command higher market premiums.

The ruby has been awarded the “Pigeon Blood” grade on the AIGS Ruby Color Grading Scale, reflecting its color quality within AIGS’s proprietary classification system. The stone displays good transparency, pleasing internal character, and balanced proportions, making it well suited for custom jewelry designs, romantic statement pieces, or collectors seeking a certified, untreated ruby with documented origin and laboratory verification.

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.
