Worlds most famous coloured gemstones


What is a gemstone?

Have you ever been digging about your back garden and thought I wonder if I could find some precious stone amongst the rocks and dirt, well it might be good to firstly know what to look for! Gemstones can be defined as a precious or semi-precious stone. They are usually one cut, and polished.

For a stone to qualify as a gemstone the stone must be hard enough to withstand constant use and handling and are normally beautiful and rare. Most gemstones are mineral gems and are found in rocks or gravel but there are a few well known ones such as pearl, coral and ivory that can be found in plants and animals. So now that we know what a gemstone is made of, let’s look at some of the most amazing gemstones throughout history.

The Cora Sun-Drop Diamond

 The Cora Sun-Drop DiamondFirstly let’s start with the biggest of them all, every now and then we come across gemstones that are so rare that they can only be awed at and the Cora Sun drop diamond is definitely one of them. The Cora diamond is the world’s largest known pear-shape diamond at 110 carats. Found in South Africa in a pipe, after some time in the Natural History Museum it was sold for over 10 million dollars to Cora International who named it and took six months to cut the diamond into its shape today. It is thought to be between 1 and 3 billion years old and auctioned in Sotherbys for 12.4 million dollars making it the eight most expensive diamonds ever sold at auction!

The Hortensia Diamond

The Hortensia DiamondNext we have the Hortensia diamond, this incredible 20 carats diamond has a pale orangey with a hue of pink to it and gets its name from Hortense de Beauharnais, who was the Queen of Holland. Hortense was actually the daughter of the Empress Josephine, who was the step-daughter of Napoleon Bonaparte and the mother of Napoleon III. This particular piece was among those stolen in 1972 and was in face recovered in the attic of an old house in the Halles district of Paris. When the French crown jewels were sold in 1887 this piece was absent from the lot due to the historical importance of it.

The Tiffany Diamond

The Tiffany DiamondWe saved the best till last, in 1877, a rough diamond made up of 287.43 carats was found in the Kimberly mines of South Africa. In 1878 Charles Lewis Tiffany bought the diamond and had it sent to Paris where it was resized to be an incredible 12 carats and was officially named the Tiffany’s Diamond. The incredible jewel can be seen to be worn by Audrey Hepburn in the iconic movie Breakfast at Tiffany’s.
