Pink Diamond from the Argyle-Mine

They have some pink diamonds from the Argyle-Mine in Australia and they show it. Pink diamonds from that mine can fetch about 10 times the price like a normal white diamond of similar quality and size. The diamond right above costs as much as a nice fully equipped Rolls Royce.

By nature colored diamonds are rare and expensive. During formation of the carbon deep inside the earth certain minerals were present as the carbon crystallized by pressure and heat.

These minerals became trapped inside the diamond during the process of crystallizing of the carbon; the outcome of this process is a colored diamond since this inclusions couldn't escape.

Usually pink diamonds are mined in India, Brazil and Africa, but the Argyle

Diamond Mine is the largest producer of pink diamonds now. The pink diamonds mined in India, Brazil and Africa come out from a geological formation called kimberlitic plates

The Argyle diamond mine finds the pink diamonds from a rock formation called lamproite. Volcanic magmas solidify into kimberlite and lamproite but are not the source of diamonds. They are only the riser that bring diamond together with other minerals and mantle rocks to Earth's surface. Although rising from much greater depths than other magmas, these pipes and volcanic cones are quite small and rare.

It is not very clear what produces the pink hue in pink diamonds. Some guess that the pink hue is a reflection from a crystal distortion. This would explain the florescent pink hue presence.

Gemologists believe the pink diamond hue is not created from any element trapped inside; it rather looks as if tiny abrasions along the diamonds multiple grains are responsible for reflecting the pink hue. The pink diamonds found in the Argyle diamond mine are clear under the microscopic.

The Gemological Institute of America has categorized the pink diamonds into five

different primary diamond color grades. The diamond color classifications are pink, purplish pink, brownish pink, orange pink and pink champagne.

With the prospect of supply depletion of the pink diamond by year 2017, the diamond market can look forward to the fact that the already rare pink diamond will remain a prized and rare diamond jewelry collectors item and possibly subject to being considered as valuable as the famous diamonds that are currently displayed and kept by museums around the world.

A Ecuadorian diamond collector Don Pedro Davilla (1710-1775), had 16 diamond crystals in his enormous diamond collection of over 8,000 total diamond specimens. The Austrian banker and businessman Jacob Friedrich von der Null, whose huge mineral collection, curetted by the prominent mineralogist Friedrich Mohs, was considered to be the best in Vienna had 36 diamond crystals (Mohs, 1804)


Before the second half of the 19th century, diamonds were mined from alluvium only, that is soil or sediments deposited washed out by a river or running water. The great South African diamond mine findings in the 1860's revealed that the very rare rock type kimberlite is the true home of diamond deposits. The first diamond crystals were found loose in the so-called "yellow ground" of weathered kimberlite, and the unaltered "blue ground" below showed diamonds too.
