RED SCARLET TRIO

Though gem connoisseurs would agree that all natural fancy colored diamonds are prodigiously rare, none could remotely challenge red diamonds as the rarest occurrence in nature. The cause of scarlet hue in diamonds still remains a mystery to gemologists and scientists. Many suggest that it is due to an uncommon deformation in its atomic structure, same as that in its pink counterparts. Indeed, natural diamonds of reddish hue are graded as ‘Fancy Red’ by GIA only if they have achieved the highest level of colour with their vibrancy. Red diamonds do not fall into the usual diamond colour grading scale, as the words ‘vivid’ and ‘intense’ are considered superfluous.

Modern sources for red diamonds are Brazil and Australia, yet their discovery are such rare occasions that only nine red diamonds were produced between 1983 to 2012 from the famous Australian Argyle mine which is the world’s largest supplier of natural pink diamonds. Some people even claimed that there are only approximately thirty red diamonds known to exist to date, with the majority of them less than half a carat in size.

This brooch, where three of such exquisite red treasures are mounted, represents a singular occasion in which the description ‘rarer than rare’ is an understatement. The possibility of owning one red diamond is seemingly unimaginable for many collectors, and to own three of them is truly an opportunity of a lifetime.
