“Kastra” Australian sapphire in diamond halo.
A custom designed and made ring by ellissi for a client.
18 ct white gold, set at its centre with a dark Australian sapphire, surrounded with round brilliant cut diamonds. The central sapphire has a fine polished bezel raised slightly above the outer halo of round brilliant cut diamonds.
Australian sapphires are less costly than the Ceylon sapphire type, and are generally of darker colour. This one was very dark , as this was the client requirement, some can be so dark they are in fact jet black to the eye.
Lighter blues are also possible and more common, to a more royal blue tone, these command the highest cost for the Australian sapphire type.
