Diamonds are one of Nature’s most wonderous gifts. Transformed from carbon under immense pressure and unbelievable heat, diamonds represent the mystery of creation, but through Man, by cutting and polishing, it becomes an amazing object of beauty and allure.

Throughout history and the centuries past, diamonds have been the folklore of Kings and Queens, countries and wars. Whilst in contemporary times, diamonds are readily available to the world at large, Nature’s largest and most perfect endowments are as before only available to a select few.

Large flawless diamonds are the paragon of white diamonds. Rarer still are D/Flawless Type IIA diamonds. These are the most chemically pure type of diamonds and have exceptional optical transparency. Extraordinarily limpid, they have been compared to pools of crystal waters or drops of frozen ice. First identified as originating from the famed Golconda region of India, Type IIA diamonds are now recovered in all major diamond producing regions. Two famous examples of Type IIA diamonds are the Cullinan I and the Koh-i-Noor, both part of the British Crown Jewels.


Discovered in 2011 from the deep mines in Southern Africa, the 299 carat rough of this oval diamond is one of the largest and most beautiful diamond rough found in recent years. Carefully and meticulously worked over months, step by step, through the skills and artistries of the best diamond master cutters and polishers to guarantee the greatest standards of proportionality and beauty, man was able to transform Nature’s rough endowment into a mesmerizing object of enthralling beauty.

The Perfection and Harmony of Nature and Man together is aptly exemplified by the magic of these alluring diamonds, one of the hardest and most precious materials known to mankind.


The magic of the carat number “100” makes for an auction legend. The appearance of a 100 carat D-Flawless diamond is always an international newsworthy event.
