"sterling silver charms for charm bracelet"Gemologists have confirmed that a small orange stone found by a Thai truck driver in his £1 sea snail snack is a rare Melo pearl that could be worth more than £70,000.

The trucker had also bought half a kilo of fresh fish, prawns and clams, which they grilled over hot coals. They first thought it was just a ‘snail egg’ but realised it may have been one of the rarest pearls in the world, an orange melo pearl, after seeing news of another find last month. He said: ‘I knew as soon as I saw the pearl that it was special. I’ve put the pearl in a safe at the bank and we will sell it, but we’re not a in a hurry. So I’m happy that we have the certificate to prove it.

The worker and his wife, Wasana, 44, found the orange stone after boiling the snail and eating it with their son who bit into something hard.

He said: ‘My family and neighbours all gathered to take a look at the stone and agreed that it was something we’ve never seen before. The family said they were shocked when their son spat out a beautiful orange pearl the size of a coin and weighing 7 grams. Experts said the stone’s value is as much as someone would be willing to pay – but market prices could be thousands of dollars per carat, depending on the quality. The delighted father is now having the suspected pearl authenticated but believes he could earn hundreds of thousands of pounds for it. Similar pearls are selling for $1,700 (£1,226) per carat.
