*Offered loose; mounting into the pictured solitaire is available upon request.
Unmistakably rare and crafted by nature, this GIA certified natural 8.55 carat round diamond delivers pure brilliance with impressive presence. A bold, well-proportioned round brilliant, this stone combines a substantial 8.55 carat weight with a classic K color and SI2 clarity, making it a standout choice for collectors, engagement buyers, and anyone searching for a big, real diamond that reads beautifully on the finger.
The diamond’s excellent polish, excellent symmetry, and excellent cut grading maximize light return and scintillation, while faint fluorescence ensures reliable performance across lighting environments. With a depth of 60% and a table of 59%, and precise measurements of 13.23 x 13.19 x 7.92 mm (average diameter ~13.21 mm), this round delivers strong spread for its carat weight and an impressive visual impact. Whether you’re shopping for a loose diamond, comparing diamond quality, or planning a custom diamond set, this stone offers exceptional value in its class.
A classic choice for an engagement, this natural diamond reads as an enduring symbol of love and timeless style. The stone is ideal for a solitaire setting where its size, sparkle, and proportions will remain the focal point. The ring shown in the photos is an optional mounting and not the primary offering, the main emphasis is the diamond itself, available loose for buyers who prefer to choose their own setting or to keep it as an investment-quality loose diamond.
