Christie’s Important Jewels is currently operating an online auction throughout November which includes the private collection from the late Dame Vera Lynn.
The company said bidding, which opened on 4 November, will begin closing lot by lot on 18 November.
A highlight of the auction is said to be a bracelet formerly owned by the late Dame Vera Lynn, which will be sold to benefit The Dame Vera Lynn Children’s Charity set up in 2001.
The charity has reportedly helped more than 600 families who have children affected by cerebral palsy.
In addition, part of the Dame Vera Lynn collection is a “beautiful cultured pearl”, diamond and enamel bracelet, (estimated at £8,000-12,000).
The bracelet features an enamel plaque depicting the “iconic image” of blue birds flying over the White Cliffs of Dover, referencing Dame Vera Lynn’s wartime hit record.
Christie’s claimed the leading lots of the sale is an elegant Edwardian garland design tiara (estimated at £45,000-65,000) and an “impressive” Art Deco diamond and ruby cabochon strap bracelet by Drayson (estimated at £40,000-60,000).
Other items include a “rare” antique foil-backed diamond collar necklace with a detachable cluster pendant (estimated at £100,000-150,000), and a limited edition diamond “Crash” bracelet watch by Cartier (estimated at £40,000-60,000).
The auction house currently offers a variety of jewellery such as a group of Victorian insect brooches, opulent Belle Epoque and Art Deco jewels, bold yellow gold gem-set and enamel designs from the 1960s to 1980s.
