*Offered loose; mounting into the pictured solitaire setting is available upon request.
Remarkably rare and crafted by nature, this GIA certified natural 5.70 carat cushion cut diamond delivers pure brilliance with presence and personality. The generous measurements of 11.87 x 9.20 x 6.41 mm (ratio 1.29) produce a substantial spread and classic cushion silhouette that reads large in hand. Color I offers a warm, near‑colorless appeal that balances exceptional value with visible impact, while SI1 clarity provides lively sparkle with inclusions that do not compromise the stone’s eye appeal. With Excellent polish and Excellent symmetry, the diamond shows crisp facet reflections; medium fluorescence can add a soft glow under certain lighting conditions. Whether you are searching for a loose diamond, a loose natural diamond, or a standout engagement stone, this 5.70ct cushion is a compelling choice-perfect for buyers looking to buy loose diamond or those shopping diamond jewelry and diamond set options.
This diamond is offered loose, and it can also be set into the solitaire setting shown in the photos upon request. When you inquire, please mention that you would like the diamond mounted in the ring, and we will add this option to your order.
Please note: The appearance of the diamond and ring may vary slightly from the photos due to lighting, photography, and the natural characteristics of both handcrafted jewelry and diamonds.
