Chairman's Notes

This ring has been assessed by our in-house gemmologists:

The rubies are most likely to be from the old Burmese mines.

The firm of Oscar Heyman & Brothers was founded in 1912 in New York City, and since its inception has been a manufacturer of handmade jewellery of the finest quality.

The firm’s exacting craftsmanship was contracted out to other jewellers of great renown with Cartier as their first customer, and a list which was soon to include Van Cleef & Arpels, Tiffany & Co, Bailey Banks & Biddle, and Marcus & Co to name a few. There is a prestige to owning an Oscar Heyman piece, as the attention to detail and fine quality materials is 'de rigueur' for the firm. They are the jeweller's jeweller, and are only recently being recognided for their lasting contribution to jewellery history.
