london - The owner bought the ring on an English curiosity market for a win and wrote 10 pounds. The small thing, however, turned out to be a diamond jewel, which converted 757,000 euros on Wednesday at an auction at Sotheby's in London.
The yield was also twice as much as the auction house had estimated in advance. The weight of the ring was found to be 26. 27 carat (1 carat = 0.2 gram). The grinding shape was called by experts as 'cushion', rectangular with rounded corners. The ring turned out so unique that he even got a name: Tenner. According to the experts, he dates back to the nineteenth century.
The buyer bought the ring in the eighties and had no idea of the value. He considered it a fun and decorative thing, according to The Guardian.
