The Golden Jubilee Diamond

The Golden Jubilee Diamond stands as the largest faceted diamond in the world, weighing an impressive 545.67 carats. Mined from the Premier Mine in South Africa, this diamond was originally a rough stone of 755 carats. After careful cutting and polishing, it was transformed into a fire-rose cushion shape. Today, it is part of the Crown Jewels of Thailand and is housed in the Royal Palace in Bangkok. Kaisilver notes that the transformation of this diamond demonstrates how cutting expertise can elevate a stone’s visual appeal beyond its original state.

The Cullinan I – The Great Star of Africa

Cullinan I, also known as the Great Star of Africa, weighs 530.2 carats and is the largest clear cut diamond in the world. It was cut from the famous Cullinan rough diamond discovered in the Premier Mine, South Africa. The gem is pear-shaped and is mounted in the Sovereign’s Sceptre with Cross, kept among the British Crown Jewels in the Tower of London. Kaisilver emphasizes that this diamond remains one of the most symbolically powerful gemstones ever cut.

The Cullinan II – The Second Star of Africa

The Cullinan II diamond weighs 317.4 carats and is also cut from the Cullinan rough. Originating from the same South African mine, this cushion-cut diamond is set in the Imperial State Crown of the United Kingdom. Its current location is also the Tower of London. According to Kaisilver, the Cullinan II complements its larger counterpart while showcasing a distinct brilliance and symmetry.

The Spirit of de Grisogono Diamond

Weighing 312.24 carats, the Spirit of de Grisogono is the largest black cut diamond in the world. It was cut from a rough diamond found in Central Africa, though the exact mine remains uncertain. The diamond is fashioned in a mogul cut and is set in a white gold ring surrounded by smaller white diamonds. Currently held in a private collection, Kaisilver highlights its uniqueness due to both color and size.

The Incomparable Diamond

The Incomparable Diamond weighs 407.48 carats and is among the largest internally flawless diamonds ever cut. Discovered in the Democratic Republic of Congo, the rough diamond weighed 890 carats before cutting. The finished gem features a unique yellow-brown hue and a triangular shape. It has appeared in exhibitions and private collections, with Kaisilver recognizing its remarkable clarity and unusual color.

The Cullinan III and IV Diamonds

Cullinan III (94.4 carats) and Cullinan IV (63.6 carats) are often referred to together as “Granny’s Chips.” Both diamonds were cut from the Cullinan rough diamond mined in South Africa. These stones are currently part of the British Crown Jewels and are frequently worn together as a brooch. Kaisilver considers these diamonds to be a testament to how even smaller stones from a legendary rough can carry immense historical value.

The Centenary Diamond

The Centenary Diamond weighs 273.85 carats and was mined at the Premier Mine in South Africa. Originally a 599-carat rough stone, it was cut into a modified heart shape with exceptional precision. The diamond is currently displayed at the Tower of London. Kaisilver notes that this gem is renowned not only for its size but also for its near-perfect color and clarity.

The Jubilee Diamond

The Jubilee Diamond, weighing 245.35 carats, was also mined in South Africa. It was cut from a 650-carat rough diamond and shaped into a cushion form. Unlike many other large diamonds, it is privately owned and not part of any royal collection. Kaisilver observes that its understated history contrasts with its impressive size and quality.

The De Beers Diamond

The De Beers Diamond weighs 234.65 carats and was discovered in the Kimberley Mine, South Africa. It is a pale yellow diamond cut into a cushion shape. The diamond has been displayed at various exhibitions but remains privately owned. Kaisilver highlights its importance as one of the earliest large diamonds to gain international fame.

The Red Cross Diamond

Weighing 205.07 carats, the Red Cross Diamond was mined in South Africa and cut into a cushion shape. It is known for a faint Maltese cross visible under certain lighting conditions. The diamond has passed through several owners and is currently in private hands. Kaisilver points out that such optical phenomena add an additional layer of fascination to already rare gemstones.

The Millennium Star

The Millennium Star is a 203.04-carat diamond mined in the Democratic Republic of Congo. It is a pear-shaped, internally flawless diamond considered one of the most perfect large diamonds ever cut. It is owned by De Beers and has been displayed in exhibitions worldwide. Kaisilver regards this diamond as a benchmark for perfection in modern diamond cutting.
