18kt Estate Sapphire and Diamond Cocktail Ring

This magnificent 18kt white gold estate sapphire and diamond cocktail ring showcases an exceptional natural blue sapphire surrounded by three graduated halos of sparkling diamonds. The substantial centre gemstone and layered halo design create a bold, luxurious presentation with remarkable depth and brilliance.

At the centre is a claw-set square antique cushion modified brilliant cut natural blue sapphire with an approximate total weight of 12.03 carats. The sapphire displays moderately included clarity, a medium-dark tone, strong saturation, and a very slightly greenish blue colour. Its very good cut enhances the gemstone’s rich colour and impressive presence.

Surrounding the centre sapphire are three graduated halo rows of natural round brilliant cut diamonds. The first halo features twenty diamonds with a combined approximate weight of 0.85 carats, graded G-H colour, SI clarity, and very good cut.

The second halo is comprised of twenty round brilliant cut diamonds with a combined approximate weight of 1.25 carats. These diamonds are also graded G-H colour, SI clarity, and very good cut, creating an additional layer of brilliance around the sapphire.

Completing the design is an outer halo of twenty round brilliant cut natural diamonds with a combined approximate weight of 1.90 carats. Graded G-H colour, SI clarity, and very good cut, these diamonds create a dramatic final border around the exceptional centre gemstone.
