How much is a pink diamond worth?
Pink diamonds are some of the rarest and most desirable diamonds in the world. Their unique pink colour is caused by structural defects in the diamond's crystal lattice, and only a small percentage of diamonds have this characteristic. As a result, pink diamonds are highly sought after and can command high prices at auction. The Argyle mine was the source of 90% of the world’s pink diamond supply, and following its closure, these gemstones have become even more rare, accounting for their exponential growth potential.
The price range for different types of pink diamond
Pink diamonds come in a range of shades, from pale pink to deep, vibrant pink. The intensity of the pink is a major factor in determining the value of a pink diamond. Generally, the more intense/saturated the colour, the higher the price.
Light Pink Diamonds: These diamonds have a pale pink color and are an entry level pink diamond. They can range in price from $3,000 to $8,000 per carat. However, Pink Diamonds of Argyle origin reach this same price at 0.1ct or less.
Fancy pink diamonds: These diamonds have a more intense pink colour than light pink diamonds and are more valuable. Prices for fancy pink diamonds can range from $10,000 to $30,000 per carat, depending on the intensity of the colour. Argyle pink diamonds instead reach $30,000 at approximately 1/10th of a carat.
Intense pink diamonds: These diamonds have a deep, vibrant pink colour and are the most valuable of pink diamonds. Prices for intense pink diamonds can range from $30,000 to over $100,000 per carat, depending on the size and quality of the diamond. Argyle pink diamonds, being the most rare, are far more valuable, hence their price, with intense pink diamonds reaching upward of $600,000 for half a carat.
The price range by grade of pink diamonds
The pink diamond grade, also known as the Four Cs (cut, clarity, colour, and carat weight), is another factor that affects the value of a pink diamond.
Cut: A well-cut pink diamond will have a more brilliant and sparkling appearance, which can increase its value. The cut of a diamond is determined by the proportions, symmetry, and finish of the diamond, and it plays a major role in the overall appearance of the stone. A well-cut pink diamond will have a beautiful sparkle and will be more desirable than a poorly cut diamond.
Clarity: Pink diamonds with fewer inclusions (internal flaws) and blemishes (external flaws) will be more valuable. Clarity is a measure of the number and size of inclusions and blemishes in a diamond, and it is graded on a scale from flawless (no inclusions or blemishes) to included (significant inclusions or blemishes). A pink diamond with a high clarity grade will be more valuable than a diamond with a lower clarity grade.
Colour: As mentioned earlier, the intensity of the pink colour is a major factor in determining the value of a pink diamond. The colour of a diamond is graded on a scale from D (colourless) to Z (light yellow or brown). Pink diamonds are graded on a separate scale, with fancy light pink being the lowest grade and fancy vivid pink being the highest. The more intense the pink colour, the higher the value of the diamond. Argyle mined pink diamonds are graded on another scale, categorising each stone by its undertone and pink intensity.
Carat weight: The larger the pink diamond, the more valuable it will be. However, the value of a pink diamond also depends on its rarity and quality, so a smaller, higher-quality diamond may be worth more than a larger, lower-quality diamond.
It's worth noting that Argyle pink diamonds are among the most expensive diamonds in the world, and their value can vary significantly based on a number of factors. If you're considering purchasing a pink diamond, it's important to do your research and work with a reputable diamond dealer to ensure that you're getting a fair price.
In conclusion, pink diamonds are rare and highly sought after, and their value can range from a few thousand dollars for light pink diamonds to over $500,000 for intense pink diamonds. The value of a pink diamond is influenced by its colour intensity, grade, and carat weight, as well as its rarity and overall quality.
