A gold necklace brought by a lady to an auctioneer's valuation day, when members of the public are invited to have their collectibles inspected, could bring £2,000-3,000 in a March 21 auction.
Experts noticed that the piece in question was inside a cloth covered box with Guild Of Handicrafts and the London Brook Street address embossed in gilt on its lid.
Inside, the necklace itself was interspersed with blister pearls and an enamel pedant styled to resemble a snowdrop.
Closer inspection by the auctioneer's experts revealed that the necklace hadn't only been crafted by Guild of Handicrafts, but also enamelled by the firm's master enameller, John Kelly.
Also in the box was the gold necklace's original bill of sale for £10 and 10 shillings from the early 1900s.
The Guild Of Handicrafts necklace will auction alongside another valuation day "find", an early 20th century opal dragon pendant and necklace.
The piece is crafted in the shape of a rampant dragon. Its body is laid with over 300 opals in place of scales, alongside its green enamel eyes and a snarling face.
This piece's prior owner was Anne Horniman, best remembered for establishing the Abbey Theatre in Dublin which opened in December 1904, and later the Gaiety Theatre in Manchester, the UK's first regional theatre company. (She also cycled over the Alps twice!)
This striking and unique piece is estimated to sell for £3,000-5,000.
