Boucheron Burmese ruby and diamond ring, French, circa 1930.

The ring is in excellent condition.

The Burmese ruby at the centre of this piece is particularly fine, displaying an unusually high degree of clarity. Rubies are naturally included gemstones, and to find a Burmese example of such exceptional transparency, particularly one that has not undergone heat treatment, is exceedingly rare. Its quality is entirely in keeping with Boucheron’s long-standing reputation for sourcing exceptional stones.
Boucheron's passion for exceptional gemstones is perhaps best illustrated by its notorious Book of Stones (Livre des pierres), an extraordinary archival register documenting the precious gems that passed through the maison. Far more than a simple inventory, its entries recorded the weights, prices and provenance of individual stones, together with the identities of their buyers and sellers, offering a fascinating insight into the distinguished clientele of the Parisian house.
Boucheron’s international reputation was strengthened by the opening of their London boutique on New Bond Street in 1903, extending the reach of the Parisian maison to British aristocracy and high society.
While the house’s principal workshops remained in Paris, jewels created there would also have been offered to its London clientele which is thought to be the case with this ring.
