Rio Tinto, one of the largest diamond mining companies in the world, presented the largest red diamond eve found from its Argyle mine in Australia. The Argyle has already gained a widespread following for being a premier source location for pink diamonds- with the company holding the 'Argyle Tender', a grand auction for many of its fancy colored diamond finds (predominantly pink colors in the finest lots).
This 2.11 ct. radiant-cut fancy red diamond, is simply ethereal in its brilliance and splendor. Named the "Argyle Everglow", it has recently been acquired by Optimum Diamonds LLC, for an undisclosed amount, along with winning another lot from the tender- the "Argyle Liberte", a 0.91 ct. violet colored diamond.
Red diamonds are much more rare then their colorless counterparts of the same size and clarity, however if you're looking for more affordable alternatives to the stone, some jewelry dealers do trade in treatment-enhanced red diamonds, where the stone itself is indeed a genuine diamond, but the red color was introduced via artificial processes at a laboratory. These would command significantly lower prices than their naturally colored counterparts, but are still worth a good value in terms of investment and appreciation.
Here in the Philippines, red colors of diamond aren't as frequently seen in many jewelry shops, but collectors of rare gemstones are quite familiar with the beautiful variety. Jewelers mostly concentrate on keeping inventories of colorless diamond, as these are probably the most known and appreciated kind of diamond within the high-end shopping districts of Metro Manila.
