Jewellery worth up to £30,000 has been discovered 15 years after it went missing. The collection belonged to a grandmother, but relatives could not find it after she died. More than a decade after her death the jewellery was discovered in an old shoebox. Perth based auctionner Nick Burns is selling the items on behalf of the family. "The family assumed all of the jewellery had been sold and she had spent the money." he said. "After all these years it turned up in a shoebox which was right at the bottom of a stack of boxes. They were shocked because they presumed it lost a long time ago. It was quite bittersweet." The collection is a mix of heavy gold, bracelets, earrings and rings set with gems including diamonds, emeralds, sapphires, rubies and aquamarine and pearls. Mr Burns expects the items to sell form between £20,000 and £30,000 when they go on sale at Lindsay Burns auction house next week. Bidders from all over the world are expected to make offers online. "Most of it looks like the style of the Edwardian-era through to the late 19th and early 20th century," he added. "Some of the higher value rings are evocative of the 20's and 30's Art Deco era where woman would have worn the jewellery to cocktail parties. It will all sell quickly. There are some lovely pieces and we have already had interest from all over the world." This discovery by the family, who live in Fife, comes after Mr Burns found an eggbox full of what the owners thought was "tat", at the start of the year, which turned out to be worth £25,000. Mr Burns said: "it's amazing how much stuff is destined for the charity shop or the bin and turns out to be worth tens of thousands."
