75th Post

This is my diamond post. 75 is usually represented by Diamonds. So let's talk about them!
The Four C's

CARAT is the diamond weight.
  • Carat is a measure of weight not of size.
  • One carat is equivalent to 200 milligrams.
  • One carat can also be divided into 100 “points.” A .75 carat diamond is the same as a 3/4 carat diamond.
  • Cut and mounting can make a diamond appear larger or even smaller than its actual weight.

CLARITY How many flaws {inclusions} does the diamond have?

  • Naturally-occurring features {inclusion} provide a special fingerprint within the stone.
  • Inclusions may look like tiny crystals, clouds or feathers.
  • The position of inclusions can affect the value of a diamond.
  • Inclusions are ranked on a scale of perfection, known as clarity.
  • Some inclusions can be hidden by a mounting, thus having little effect on the beauty of a diamond. An inclusion in the middle or top of a diamond could impact the dispersion of light, sometimes making the diamond less brilliant.
  • The greater a diamond's clarity, the more brilliant, valuable and rare it is.

COLOR How colorless is the diamond?

  • Diamonds are found in almost every color of the rainbow, but white-colored diamonds remain most popular.
  • Truly colorless stones are treasured for their rarity.
  • Diamonds also naturally come in intense shades of blue, green, yellow, orange, pink or red.
  • These diamonds are called ‘colored fancies’ and are extremely rare and highly treasured.

CUT is the shape the diamond is cut into.

  • Nature determines so much about a diamond, but it takes a master cutter to reveal the stone’s true brilliance, fire and ultimate beauty.
  • Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and it loses its value.
  • Cut also refers to shape—round, square, pear, or heart for example.
  • A round diamond is symmetrical and capable of reflecting nearly all the light that enters. It is the most brilliant.
  • Non-round shapes, are called fancy cuts.

Diamond Facts

  • Diamonds were formed long before the dinosaurs were here. The youngest diamond is about 900 million years old. The oldest was formed over 3 billion years ago.
  • Diamonds are like snowflakes, no two are alike.
  • The rarest diamond color is red.
  • The first diamonds came from India over 2800 years ago.
  • Each stone usually loses about half of its weight during the cutting and polishing phase.
  • Less than 5% of all the diamonds made into jewelry are larger than one carat.
