Marvel at the sheer variety, beauty and colour of the minerals, gems and rocks on display. The gallery features a glittering and colourful display of a multitude of stones, both familiar and unusual, with a display of how diamonds are formed and cut.
For many of us, the greatest pleasure of gemstones is to wear them mounted in jewellery, and the Royals are no different. The Queen’s crown contains sapphires, tourmalines, amethysts, topazes and citrines set in gold. You’ll find examples of all these gems glistening in the Earth's Treasury gallery.
Diamonds are made of carbon that has crystalised deep within the Earth. In the early 14th century craftsmen refined cutting and polishing techniques to take full advantage of the extraordinary way in which diamonds split light into a rainbow of colours. See the process of taking diamonds from their raw rock form to dazzling stones and learn about caret strength.
This dazzling gallery displays fine specimens of the 1000s of colourful gemstones, rocks and minerals on which we depend. Get a rare glimpse of some truly precious treasures, including this beautiful rainbow of gems exhibit.
Gold is among the most treasured of Earth’s metals and has long been used as a means of exchange as well as a symbol of power and wealth. The gallery features examples of the forms in which gold can be found.
This polished, kidney-shaped mass is hematite. It’s one of our most important minerals because it is a key natural source of iron.
Marvel at a mineral called jadarite, which has the same chemical composition as kryptonite. Discovered in Serbia in 2006, the mineral is composed of sodium, lithium, boron silicate and hydroxide. Those are the same ingredients listed for kryptonite in the film Superman Returns. The only difference is fluorine, which gives kryptonite its green colour.
