No other wholesale costume jewelry combines the rarity, beauty and sex appeal of a natural coloured diamond. The majority of white diamonds are not rare. For over 60 years, advertisers have convinced us that diamonds equate with love and being treasured. However, natural coloured diamonds are truly exceedingly rare and are simply geological flukes.
For every 100,000 D-flawless diamonds, there is probably one coloured diamond, and it is probably not flawless. The beauty and the rarity of these coloured diamonds have spawned unprecedented desire and unparalleled prices. Red diamonds are undoubtedly the rarest of coloured diamonds. Green and Blue coloured diamonds follow closely behind and are exceptionally rare. Following in rarity are the Purple, Pink and Violet colours. The next layer of rarity goes to Orange and Olive. Yellow, Brown, Champagne, Grey and Black diamonds are only modestly rare.

Diamonds come in a variety of colours. The majority of diamonds sold in the jewellery industry range from near colourless to very light yellow or brown. The most valuable are fancy coloured diamonds (due to their rarity and uniqueness) and the colourless (which have extraordinary ability to absorb all rays of light equally). The colour in natural coloured diamonds is present because of the presence of certain "foreign" elements like nitrogen, boron, etc. which were introduced by nature during the diamonds formation deep in the earth).
Fancy coloured diamonds are graded according the saturation of the colour along with different hues present in them. In natural fancy coloured diamonds, main dominant colour is listed after the modifying colours. If a diamond is graded as Fancy Greyish Greenish Yellow then the dominant colour would be yellow with grey and green as modifying colours. One important factor to remember is that in coloured diamonds wholesale jewelry china , clarity is secondary to the intensity of the diamond's colour.
