Hot on the heels of a magnificent auction from Bonhams New York auction last week, where Burmese rubies, Kashmir sapphires, Colombian emeralds, plus an impressive selection of magnificent diamonds together with a large collection of David Webb jewellery raised $4.5 million.

This week it was the turn of the Bonhams London Fine Jewellery sale, where the season's most talked about emeralds caused somewhat of a stir. Three pieces of Art Deco diamond and emerald jewellery, attributed to Hennell, became the subject of a bidding frenzy in Bonhams New Bond Street salesroom, eventually selling for a total of £1,928,250.

Emily Barber, Director of Bonhams Jewellery UK, said:

These jewels are simply magnificent. Superb emerald specimens like this do not come to market very often so we're delighted to bring them to auction for the first time. The crescent-shaped emerald is no doubt an historic Indian gem, cut to maximise its "green fire" and the sugarloaf cabochon emerald, a cut favoured by early 20th century Art Deco jewellers, is one of the finest examples we have seen.

Caroline Morrissey, Senior Jewellery Specialist, Bonhams New York, after the New York fine jewel auction said:

Rubies are far rarer than colourless diamonds, a fact that has been recognised in the world-record breaking prices they set at auction. Given the international appetite for specimen rubies together with a greater appreciation of this gemstone, we are anticipating keen interest in these pieces during our previews in New York, LA, Geneva and Hong Kong.

Here are a few of our favourites from both the London and New York auctions:
