The taaffeite stone, which ranges in color from clear-mauve to purple-red, was named after Richard Taaffe, a gemologist who discovered it in 1945. The only taaffeite stones on the planet would only fill half a measuring cup. The other half would be filled with ordinary garnet.
Taaffeites are quite rare, being found in only 0.5 percent of all garnets that are mined. They're also the most fragile gemstone, losing up to 3% of their weight per square inch when cut into jewelry.
The rarity of this gem makes it valuable too. A carat (ct) weighs about 200 grams (7 ounces), so a taaffeite worth $10,000 would be about an inch long by 1/4 inch wide. That's smaller than a pencil tip!
Taaffeites come from Namibia and South Africa. Garnets are the result of volcanic activity, while taaffeites were formed under the earth's surface through the interaction of molten rock and metal. This shows that they must be very close chemically to each other. For example, if you heated up a taaffeite to a high temperature, it would turn into a ruby rather than remain as a taaffeite.

Painite was discovered in 1951 by British gemologist Arthur Charles Davy Pain and was designated as a new mineral in 1957. For many years, the British Museum in London kept the solitary specimen of the dark red crystal, making it the world's rarest gemstone. In 1996, another piece was found in Brazil's Minas Gerais state. This material is also called painite because it can be used to make jewelry like that worn by Native Americans centuries ago.
The original piece from the British Museum is about 5/8 of an inch (16 mm) wide and 3/4 of an inch (19 mm) long. The Brazilian fragment is about 1/4 of an inch (6 mm) wide and 3/4 of an inch (19 mm) long.
Both fragments are mounted on rings made of green jasper with gold bands. They are on display at the museum's Department of Mineralogy.
Semiprecious stones are those that fall between the classification of precious metals and gems. They include quartz, emeralds, sapphires, rubies, and diamonds. Painite is not considered valuable today but would have been worth more than $10,000 in 1960 when it was stolen from the museum. It has value only because it is so rare.
In conclusion, painite is the rarest semiprecious stone.
The red diamond was ranked first. This implies that if you value something beyond all others, a red diamond tattoo might be the perfect way to express your gratitude. The red diamond also means that you take life seriously. Tattoos are visible for everyone to see, which is why it's important that you only get a tattoo artist who has done many tattoos before. Never choose a beginner or an experienced tattooer, because a novice will likely cause harm if they try to work with your skin. A red diamond tattoo shows that you are passionate about something and don't let anything stand in your way when pursuing your goals.
The black pearl next to it represents mystery and intrigue. It also means that you have secrets you hide from others. Tattoos like this one are often interpreted as symbolic, so understand that readers may read into them what they want to. However, most people interpret this tattoo as a secret lover tattooed on a woman by her past boyfriends. They claim that he's filled with mysteries even after being exposed through photos or interviews, proving that she still loves him even though she's found out.
The green wreath with white flowers is meant to signify hope. It also means that you believe in resurrection and rebirth, because wreaths are made up of fresh greenery which grows back after it's been cut.
The Cullinan Diamond was the biggest gem-quality rough diamond ever discovered, measuring 3,106.75 carats (621.35 g) and discovered on January 26, 1905, at the Premier No. 2 mine in Cullinan, South Africa. It was named for the mine's chairman, Thomas Cullinan. At that time, the world record for a gem-quality diamond was just under 100 carats (20.5 g). The Cullinan remained the largest diamond discovered until 1913 when another Premier No. 2 stone was found equal in size to the Cullinan.
In terms of quality, the Cullinan was not quite up to modern standards but it was still considered one of the finest diamonds in the world. It had an intense blue color and was almost completely free of impurities. The weight of the diamond was estimated to be between 1 and 1.4 billion years old, based on its depth below the surface. Modern technology has confirmed some estimates place the age of the diamond at about 110 million years old.
Diamonds are formed from carbon atoms in rocks deep beneath our feet. The process takes millions of years. Once carbon is released by these rocks into the earth's atmosphere, it condenses into tiny particles called "nuggets". Over time, these nuggets grow larger through collision and agglomeration. If they are hot enough, they will melt and flow together.

Jadeite costs $3 million per carat. Jadeite is the most pure, rare, and vibrant gemstone in the jade family. The Paragon Diamond is the world's biggest loose diamond, weighing 137.82 carats, while the Pink Star Diamond is the most costly jewel ever sold, fetching $83 million.
Diamonds are the only gemstone that comes in a full spectrum of colors, from colorless to red, yellow, or blue. This allows for variation within the diamond industry while still being able to identify diamonds of the same quality level. Colorless diamonds are also the highest quality, as they are completely transparent; they can only be black or white. Other colors may come from iron or nitrogen impurities. Black diamonds can also be referred to as "dark diamonds", while white diamonds are often called "bright diamonds".
Jade is one of the hardest minerals on Earth and is used in jewelry for its beauty and value. It was originally used as money by Chinese farmers because of its durability. Today, jade is popular again because it is possible to find beautiful pieces that aren't too expensive.
Jade has been used since at least 350 B.C. It was probably first collected by prehistoric people who found it naturally forming along riverbanks and in other relatively inaccessible places. Over time, humans have learned how to remove jade from its source material (jadeite) using tools made from harder materials such as steel or quartz.
