3.00 ct Red (Vivid to Deep) Ruby – Cushion Cut – Unheated – Mozambique

This 3.00 ct natural ruby displays a vivid to deep red hue with strong saturation, paired with a finely executed cushion cut that enhances brilliance and delivers an elegant, balanced face-up presence. Sourced from Mozambique, one of today’s most important modern ruby origins, the stone offers a rich and visually striking appearance with excellent color depth.

According to the GRS gemstone report, there is no indication of thermal treatment, confirming the ruby is unheated—a highly desirable and increasingly rare characteristic in today’s market. An appendix note further describes the color as reminiscent of “GRS-type pigeon’s blood ruby” (without strong fluorescence), underscoring its strong saturation and trade-recognized appeal.

The ruby exhibits lively internal character, attractive transparency, and harmonious proportions, making it well suited for fine jewelry, collector acquisitions, or buyers seeking premium unheated ruby material with verified origin and respected 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.
