The world of antique jewellery is filled with many wonderful items, but sometimes the run-of-the-mill ‘commercial’ stones just don’t cut it (Pun very much intended). Sometimes, there’s a requirement for something extra special. So with this in mind, lets take a look at some of the more rare and unique and expensive precious stones available on the market.

Harlequin Opal

The Harlequin Opal is the pinnacle of beauty and rarity for patterns found in black opals. This beauty pictured is favourable because of it’s distinct tropical colouring, rich tones and pattern come together to create a truly dazzling effect. This is one of my personal favourites!

Red Beryl

Estimated to be one of the rarest gemstones on the planet, Red Beryl is estimated to be worth $10,000 (£7700) per carat. It’s value is mainly derived by the fact that Red Beryl can only currently be mined in the USA, more specifically from the Thomas Range and Wah Wah Mountains in Utah, and the Black Range, New Mexico.

Wow, okay this is a good one – This gemstone is not only extremely rare, it also has one other pretty amazing quality. It can change colour. Depending on the light source – the stone changes from a green to a pinkish hue. Although not as rare as it once was due to recent finds – this gem stone is estimated to be worth $12,000 (£9200) per carat.
