The Pink Star diamond, the world’s most costly gem, sold for an astounding $71.2 million in 2017. The Pink Star, a 59.6-carat diamond, holds the record for being the largest internally flawless fancy vivid pink diamond ever to get a GIA rating. In 1999, De Beers mined a raw diamond in Africa weighing 132.5 carats, from which the Pink Star was fashioned.
The Pink Star, formerly known as the Steinmetz Pink, made its first public appearance in 2003. It was on exhibit in Monaco and other places, and it swiftly gained notoriety as one of the most significant diamonds in the entire world. The Pink Star was purchased for $83 million at auction in 2013, but the buyer missed their payment. The diamond was later purchased again by Sotheby’s and put up for auction once more in 2017. Hong Kong jeweler Chow Tai Fook won the sale and purchased the diamond.
The ordinary opal, which costs as little as $1 per carat, is the least expensive gemstone in the world. The opal, a gemstone composed of silica and water, is prized for its brilliant hues and iridescence. Opals can be incredibly lovely, but they are not as strong as other gemstones and are relatively soft.
It is impossible to say which sapphire or ruby is more valuable because it depends on the quality, size, and color of the stone. There are some exceptions, but on general, pure red rubies are worth more than blue sapphires. For instance, one of the most priceless gemstones in the world is the Star of India, a rare blue sapphire.
In conclusion, the common opal is the least expensive gem, and the Pink Star diamond is the most expensive. Color and quality are just a couple of the variables that affect the price of sapphires and rubies. Since ancient times, gems have been cherished for their beauty and scarcity, and today, collectors and aficionados all around the world still seek them out.
