Heritage

Cullinan Diamond Mine owes its historic fame to the largest diamond uncovered – the Cullinan Diamond.

An influential building contractor named Thomas Cullinan bought the Elandsfontein farm that housed the Cullinan Diamond Mine in 1903. Less than two years later, a rough diamond was found nine metres down and protruding from the sidewall of the pit measuring a staggering 3,106.75 carats. The Cullinan Diamond was established as the greatest diamond ever found. The jewel was named after the mine’s owner and sold to the South African government who presented it to King Edward VII on his 66th birthday. The largest diamond the world has ever known was cut into nine major stones and approximately 96 smaller diamonds.

The main piece of the polished gem, named Cullinan I, or The Great Star of Africa, was the biggest of the collection and weighed an astonishing 530.2 carats. The Great Star of Africa is displayed in the head of England’s royal Sceptre while the Lesser Star of Africa, or Cullinan II weighing 317.4 carats, forms part of the British crown jewels’ Imperial State Crown. Both South African-mined diamonds are exhibited at the Tower of London.

Sir Thomas Major Cullinan remained involved with operations after the significant discovery until 1923 when he resigned as Chairman and as a prominent board member, selling his shares to move on to other ventures. Cullinan died in 1936 but his mine continued to unearth the largest and most famous gems ever known. In 2003, to commemorate the world’s most famous diamond mine, the 100-year-old mine was officially renamed the Cullinan Diamond Mine. To this day, the Cullinan Diamond Mine remains a major diamond producer.

The Big 8 Diamonds

The true brilliance of diamonds can only be captured through the amount of light that is able to penetrate the precision cut facets. To your eye, the light that is absorbed by the angle, pattern and proportion of the facets allows the stone to reflect a fiery, radiant sparkle. Cut and clarity are crucial to the fire of a diamond, which is why the Cullinan Star Cut (TM) is so unique. The 66 facets, eight more than the standard 58 facet gem diamond, ensures that each stone radiates a passion so bright and clear that it resembles heaven’s stars, at the heart of the jewel.

All Cullinan Star Cut (TM) gem diamonds are coupled with an international certification of their quality, veracity and value.
