Yellow diamonds are diamonds that contain carbon in its elemental form (carbon). Diamonds are formed deep within stars when layers of gas and dust collapse under their own weight forming supernovae. These remain intact for a long time before exploding, leaving behind elements such as nitrogen, phosphorus, and sulfur along with large amounts of carbon.

The current assessed value of a one-carat diamond (US) ranges from $1,910-$15,650, with a suggested average value of $4,280. That's more than most people would expect to receive for a stone with no special qualities other than its size and color.
Here are some more surprising facts about diamonds:
• Diamonds are the hardest material in the world. It takes at least six times as much pressure to cut through a diamond as it does to cut through steel. This makes diamonds useful for many things including knife blades and drill bits.
• Diamonds are made up of carbon atoms which form a tetrahedral structure when they are joined together. The bonds between these carbon atoms are extremely strong - stronger than any other element except helium. This means that diamonds are stable under high pressure and heat, which is why they can be found deep within Earth's crust where temperatures vary over a wide range.
• Diamonds are valuable because they are hard to find and easy to identify. They occur naturally but are also created artificially in nuclear reactors, during explosions, and by cosmic rays outside of living organisms.
A 1 carat yellow diamond can cost anywhere from $3,000 to $16,000+, depending on its quality and color intensity. The most costly diamonds are intense yellow diamonds, such as Canary Diamonds, which typically cost at least $10,000 for a 1 carat diamond. The terms AEP and OEP refer to the Medicare Annual Enrollment Period and the Medicare Open Enrollment Period, respectively. OEP can refer to a variety of various Medicare enrollment periods depending on the circumstances. For example, if you lose your job and need to change insurance carriers, the OEP would be when you can choose another carrier within the same group.
Canary diamonds were originally named after Canaria Island, now known as Madura Island, in Indonesia. The name "canary" comes from the fact that these diamonds often have yellow colors similar to those found in canaries. However, modern-day diamonds can also be colored other bright colors such as red, blue, green, and black. While canary diamonds used to be more common, today they're rarely seen because canary colors tend to be more popular with jewelry buyers.
Canary diamonds usually have larger flaws than other diamond shapes. This is because they're not taken from well-known mines so quality control is less strict. Also, since they're mostly sold by weight rather than cut, they may be mixed with higher-quality stones to make them lighter.
Canary diamonds have a history of being traded across international borders. Because they were valued more highly than other diamonds, traders often crossed paths with canary diamonds.

It sold for $6,663,300, or $1,920,259 per carat, much to the satisfaction of the family that sold it and those in the audience who understood the tale, establishing an auction record price per carat for a fancy vivid blue diamond and making it the top lot of the day. It also made an impression on people who didn't know any better than to take everything their eyes fell upon at an auction seriously, including members of the media.
In fact, the diamond had a profound effect on the market for such stones. A few months later, another fancy vivid blue diamond was unearthed in South Africa; this one cut into 59 pieces but weighing only 595 carats. The Blue Streak sold for $10 million - $1.9 million per carat. That same year, another huge fancy vivid blue diamond was found in India. It too was cut into pieces and weighed about 600 carats. The De Beers Auction House paid $15.5 million for that stone, which averaged out to just under $2 million per carat.
Since then, other large fancy vivid blue diamonds have been found and sold. In 2004, a rough 1.11-carat stone went for $500,000. In 2005, a finished diamond weighing 0.22 carats was sold for $120,000. In 2006, a second diamond with a 0.19-carat face value went for $80,000.
