Top Five Biggest Diamonds In the World

February 17, 2014

As most newly engaged men can attest, buying a diamond is not easy.  You would think that bigger is better, but there are four main criteria to consider when buying: CUT, CLARITY, COLOR, and CARAT-weight.  In a “bigger is better” world, men are drawn to diamonds with the largest carat-weight.  But, it truly is a combination of the four, that make a diamond “better”.  To best illustrate this point, here are five of the biggest (cut and faceted) diamonds in the world – notice the dramatic fluctuation in value.

#1. The Golden Jubilee Diamond, 1985

The Golden Jubilee Diamond, 1985

From: Premier mine, South Africa
CARATS: 545.67
COLOR: E-Grade Fancy Yellow Brown
CLARITY: deep cracks and several inclusions
CUT: Fire Rose Cushion Cut (Irregular Octahedron) Facets: 143
Owner: King of Thailand
Value: $4-12 million

WHAT ACCOUNTS FOR THE VALUE?
Although, the largest cut and faceted diamond in history, it suffers from cracks and inclusions, lowering its CLARITY.  While COLOR desirability is sometimes controlled by passing trends, the color white (or colorless) is the standard to which all others are judged and the color scale has been created.  Yellow is a more common color in diamonds and hence less rare making it less valuable.  This diamond’s value is mostly in its CARAT weight and CUT.

#2 Cullinan I Diamond (also called Star of Africa), 1905

Cullinan I Diamond (also called Star of Africa), 1905

Cullinan I Diamond (also called Star of Africa), 1905 mounted in sceptre
From Premier Mine, Pretoria, South Africa
CARATS: 530.4
COLOR: D-color (colorless)
CLARITY: Flawless
CUT: Pear Facets: 76
Owner: Queen Elizabeth II, mounted in the Sceptre with the Cross, Crown Jewels of the United Kingdom
Value: $400 Million

WHAT ACCOUNTS FOR THE VALUE?
NOT the largest cut and faceted diamond in history but the second largest this stone gains its immense value from its perfect CLARITY and white (or colorless) COLOR.  The CUT is not practical for much except to mount in a Sceptre or large broach which the jewel converts to.

#3 The Incomparable, 1984

The-Incomparable-Diamond

From: MIBA Diamond Mine in the Democratic Republic of Congo
CARATS: 407.48
COLOR: Fancy Brownish-yellow color
CLARITY: Flawless
CUT: Shield Shape Step Cut (Triolette) Facets: unknown
Owner: unknown
Value: $20 million

WHAT ACCOUNTS FOR THE VALUE?
This stone suffers from an odd and uncommon CUT, but what it has going for it, is its CARAT weight and CLARITY which is flawless.  One of its down sides are its less desirable brownish-yellow COLOR.

#4 The Cullinan II (also called The Second Star of Africa), 1905

The Cullinan II  (also called The Second Star of Africa), 1905
From Premier Mine, Pretoria, South Africa
CARATS: 317.4
COLOR: D-Color (colorless)
CLARITY: Flawless
CUT: Cushion Facets: unknown
Owner: Queen Elizabeth II – Crown Jewels of the United Kingdom.
Value: $200 Million

WHAT ACCOUNTS FOR THE VALUE?
It was a secondary stone off the largest uncut diamond ever found.  It has flawless CLARITY and COLOR (colorless) but is less CARATS and has a less brilliant cut, the Cushion.

#5 The Spirit of de Grisogono, 20th century

The Spirit of de Grisogono Diamond, 20th century
From: West Central Africa
CARATS: 312.24
CLARITY: unknown
COLOR: Black
CUT: Old Moghul-cut Facets: unknown
Owner: Private collector
Value: unknown

WHAT ACCOUNTS FOR THE VALUE?
Although large and CUT well for brilliance, its COLOR is less than desirable and more common, black.   Its actual value is unknown but its size makes it the fifth largest diamond ever.
