This exquisite 4.23 carat round tanzanite showcases an exceptionally rich, vivid blue colour with remarkable saturation and life. Graded VB 6/6 — the highest tier of colour intensity — the gemstone displays an estimated 80% deep sapphire-blue with subtle flashes of violet, creating the unmistakable brilliance seen only in the finest tanzanites.

Expertly cut and beautifully eye-clean, this stone delivers outstanding sparkle and brightness, with crisp facet definition that allows the colour to radiate throughout the gem. Its elegant round cut gives the stone a timeless and highly luxurious appearance, making it an exceptional choice for a bespoke engagement ring or future heirloom piece.

A rare example of elite-quality tanzanite, this gemstone also grades as AAA+ / “heirloom” quality under commercial grading systems. ( Matches the pair of 9.57 carat rounds also currently for sale )
