For non-diamond gemstones, painite is the winner of the most valuable gemstone in the world. For overall most valuable, red diamonds are worth the most money by carat weight. So, the most valuable gemstone in the world is a particular pink diamond. It broke the previous sale record of the Graff Pink Diamond by almost double the amount. The Gemological Institute of America boasted the Pink Star was the largest and most flawless naturally coloured pink diamond it had ever graded. The Pink Star Diamond is also sometimes referred to as The Pink Dream. It sold at auction in 2013 for £68,000,000 ($83,000,000 US), the highest price ever paid for any gemstone. This 59.6-carat pink diamond is known as the Pink Star Diamond. The most expensive gemstone ever was a specific diamond. So, a red diamond is a complete, perfect diamond, whereas a blue diamond contains boron, an impurity. Red and pink diamonds are not coloured by impurities, but rather as a result of miniscule defects in the lattice structure.
Red diamonds are unique among coloured diamonds because other colours in diamonds are usually effects of impurities. To this day, there are only 20-30 red diamonds known to exist. Because of this, the red diamond is among the most expensive gems in the world, priced at £820,000 ($1,000,000 US) per carat. Recently, more have been found, but it is still extremely rare and valuable.ĭiamonds come in many colours, with red being the rarest. In fact, until 2004, only two had been cut into jewellery-grade gemstones. From the first discovery in the 1950s to 2005, only 25 small painite crystals were known to exist. It is a very rare, naturally hexagonal gemstone. Painite is an interesting brick-coloured gemstone. The most valuable gem that is not a diamond is one that many have never heard of. Here, we take a look at the most valuable non-diamond gemstone, as well as the two types of diamonds that hold the records for most valuable gem by carat weight.
But the most valuable gem of all time is a type of diamond. Some types of semiprecious stones such as opal and jade regularly sell for very high. Emeralds, sapphires, rubies, garnets, and alexandrite, just to name a few. Precious stones are not always more valuable than semiprecious stones. There are many gems that are more valuable than diamonds. Paraiba Tourmaline 5,000 per carat Paraiba tourmaline is one of the rarest gemstones, and it was only discovered in 1989 in Europe.
Beyond that, colour, clarity, cut, polish, size, demand, and treatments are among other facets that are taken into consideration when applying value to a gemstone. But the price varies greatly between gemstones. Typically, a gemstone is priced by carat weight.
