Pink Diamonds are one of a group of minerals which we have decided are suitable for personal adornment, known collectively as gemstones. Archaeology tells us that the use of gemstones for personal adornment is one of the oldest Human habits, predating even the use of clothing. The qualities which define gemstones are their beauty, durability and rarity.
Its beauty to us is the obvious reason why pink diamonds are precious. Their properties of color, transparency, lustre, sheen and dispersion, which is the ability of diamonds to split white light into its spectral colors, have made them one of the most sought after gemstones.
Durability is the gemstones ability to avoid damage and degradation over time. Here diamonds are amongst the finest gemstones, being one of the hardest naturally occurring substances found on the Earth. Durability is an important quality in a gemstone as by their very nature they will be often worn or displayed. The durability of diamonds has invested them with almost mystical properties and allowed them to be passed from generation to generation.
Rarity is an essential quality of gemstones and may be more important in determining value than purely physical properties. This is a major reason why pink diamonds are precious. The Argyle Diamond Mine in Western Australia is the only known significant source of pink and red diamonds, producing over 90% of the world’s supply. Of the diamonds produced by the mine only around 5% are of gem quality and of this percentage less than 1% are pink or red.
Around 3,600 minerals are known to be present in the Earths geology but only around 100 of these possess all the qualities which will allow them to be described as gemstones. Traditionally diamonds, sapphires, rubies, emeralds and opals are considered precious gemstones. Other well known gems include, garnets, topaz and tourmaline.
Some minerals are prized for such qualities as striking colors or swirling patterns but are not transparent, durable or rare and are not considered gemstones, being known as ornamentals. Examples of these stones are onyx, jade and lapis lazuli. Organic gems include coral, amber and pearl.
This unusual combination of extreme beauty, durability and rarity found virtually only on one spot on the Earth are why pink diamonds are precious.
