Stone Details

Gem type: Diamond
Stone ID: 6449604

Red corundum — chemically the same species as sapphire, coloured by chromium — is what the trade calls ruby, and at Mohs 9 it gives way only to diamond. Most rubies in the market are heated; lead-glass-filled composites are a different product altogether. This ring is designed by Ministry of Gems and handcrafted in our own workshop.

A cushion-shaped ruby is framed by a halo of diamonds in this ring, the white border sharpening the red of the stone. The rich colour and classic halo make it a striking choice for an engagement ring or for evening wear. Crafted in gold, it is made to order in the client's size.

Every ring is made to order in your size, in half sizes from F to Z +6 on the Australian and UK letter scale. The millimetre figures are the inside circumference and inside diameter of the sizing set our workshop makes to; other charts can differ by up to half a size, so when in doubt measure a ring that already fits.

Measuring at home. Lay a ring that fits that finger on a ruler and measure the inside diameter edge to edge, or wrap a strip of paper snugly where the ring will sit, mark the overlap and measure the length for the circumference. Measure at the end of the day, check the ring passes the knuckle, and go up a half size for bands wider than 6 mm. Between sizes, or not sure? Read the full sizing guide or ask our gemmologist before we cast.

Every ring is made to order in your chosen size in our own workshop, at the price shown and in the metal pictured; most rings leave the workshop in two to four weeks, fully insured and documented. If you would like it in a different gold or platinum, choose the metal above and request a written quotation, with no payment taken until you have accepted it.
