Loose Pink Diamonds
A pink diamond stone is graded according to the intensity of color found in each individual gem. There are two main grading systems in use specifically for pink diamonds.
• The Argyle system of pink diamond grading, developed by the Argyle mine
• The Gemological Institute of America or GIA system
Both systems take into account the tones, hues and color saturation levels found in an individual pink diamond.
Although, perception of color can be extremely subjective, it is powerfully clear that the greatest factor in assigning value is intensity of color. Clarity and cut come second. At present, pink diamonds can be purchased in all cuts.
Due to its extreme rarity, the pink diamond stone was once obtainable only by the privilege of royalty or nobility. The pink diamond is in fact one of the rarest and most valuable of all diamonds.
What makes natural pink diamonds so rare?
The color of a pink diamond gem results from:
- Impurities and graining differences in the stone
- A shortage of nitrogen
- Greater compression within the earth
In short, the molecules in a single pink diamond stone are more tightly packed than those of a clear diamond. This random natural incident can only take place in the deepest reaches of a volcano. Compound these factors with some very extreme earth forces over millions of years and we start to gain an understanding of just how special loose pink diamonds really are.
Add to all of this a romantic history that spans from the Middle Ages in the mines of India, to the modern Argyle mine of Western Australia. Immediately, it becomes clear how this rare pink diamond gem has captured hearts and imaginations throughout the ages. Select your perfect pink diamond today.
