Adam’s Auctioneers’ director Claire-Laurence Mestrallet on the luxe Christmas list of jewels and gems with big savings at Dublin’s next auction

Ahead of Adam’s Auctioneers’ Christmas auction on December 5, director Claire-Laurence Mestrallet gives an insider’s guide to the key pieces going under the hammer for a fraction of their retail prices

A diamond ‘lotus between the finger’ dress ring by Van Cleef & Arpels, which retails for €39,600 is estimated to be auctioned for €15,000 to €20,000

Claire-Laurence Mestrallet is, as we speak, preparing for Adam’s Auctioneers’ final – and arguably biggest – fine jewellery and watch auction of the year.

A director of the Dublin-based auctioneers and the head of its fine jewellery and watches department, Mestrallet has examined and valued hundreds of contemporary jewels and vintage gems for Adam’s Christmas auction, with a total tally of 247 pieces going under the hammer.

But what makes this auction special? The array of impeccable and close-to-new modern pieces for a fraction of their retail prices is one of this auction’s strongest sell. This is coupled with Adam’s offering of rare collectibles, which can often fetch far higher prices than their estimated auction value, meaning there will be a piece to fit every budget and style preference.

“The auction jewellery market is a completely different market to retail and therefore value is considerably lower. All transactional costs of retail value are removed when valuing the pieces,” Mestrallet told Irish Tatler.

“Having said that, some collectible pieces can reach higher values at auction. For example, we sold a sapphire and diamond mystery-set flower brooch by Van Cleef & Arpels in September 2022 estimated at €30,000 to 50,000 which fetched €137,500 on auction day.

“Similarly, a convertible diamond bracelet/tiara (circa 1930) by Austrian imperial jewellers, Köchert, estimated at €50,000 to €70,000 was consigned by an Italian noble lady and fetched €118,750 in our last September auction. Where else would you find the same collectible pieces in Ireland?” she added.

As Ireland’s biggest auction house, Adam’s Auctioneers has become an Irish leader recognised in an international market. Opening in St Stephen’s Green in 1887, its 136-year history has earned the auction house an established reputation and an unrivalled network and knowledge bank.

So, ahead of the auction on Tuesday December 5 at 4pm in Adam’s St Stephen’s Green auction house, Dublin 2, Mestrallet rounds up her top seven picks worth making a note of.
