Yellow diamond: properties, origins, mining and interesting facts
The word "diamond" is translated from Greek as "invincible" or "sparkling." None of the artificial materials and none of the stones can damage or scratch it.
About 90% of diamonds, called “yellow”, are stones with a yellow tint. By classification, they constitute a group of "colored" diamonds. Only 10% of the remaining stones have a pronounced yellow, sunny color. For such truly unique crystals, a classification group was created - fantasy. Prices for them are incomparably higher than for stones from the “painted” group. Fantasy stones can have different shades of yellow: lemon, pear, corn, lemonade color.
Classification and properties of yellow diamonds
The very first known yellow diamond is a lemon-colored stone, faceted as a drop, called “Sancy”. Its weight is 55.23 carats.The stone was purchased in 1571 in Turkey.

At the time of the discovery, he weighed 200 grams. After cutting the weight was 100.9 carats. By today's classification, color is defined as yellow light. Brilliant shines golden rays, like a little sun. This color is worth millions of dollars.

This explains the high cost of the Graff Vivid Yellow diamond, in which all 100 carats have the pure uniform yellow light color.
The play of light on the edges is determined by the degree of transparency, which is considered on a scale of 12 to one. The lowest figure - 12 - is assigned to almost defective stones.
Often diamonds have a yellow color with a brownish or greenish tinge. Such tones interfere with the play of light on the edges and reduce the cost of a diamond.As a benchmark of pure yellow, Graff Vivid Yellow again stands. And this is not surprising. In addition to the sparkling yellow color, it has no shades: neither green nor brown.According to the above scale, it has a degree of transparency of 2.
