The first, valued at $2,500 to $3,500, is a coin, diamond, platinum and 18-karat gold necklace, produced by Bulgari in Italy. The 17-inch chain makes it a truly eye-catching item and it is likely to appeal to collectors and fashionistas alike.

Also on sale at the Quail Lodge Resort & Golf Club is a gent's nine-piece dress set, which experts predict will sell for up to $1,500.

Diamond and platinum earrings will also be sold and experts predict a final sale price of somewhere in the region of $2,000. These beautiful earrings are based around a charming floral motif, which perfectly combines elegance and playfulness.

The Bonhams sale is one of many recent auctions to feature high-quality platinum jewelry, reflecting strong demand for platinum around the world.
