Pear Diamond 530.4ct — largest cut clear diamond, set in a royal sceptre

There are diamonds, there are legendary diamonds—and then there is the Cullinan legacy, the ultimate expression of diamond supremacy within the British Crown.

At the center of this story is the Cullinan Diamond—a stone so vast that it redefined the limits of what a diamond could be.
The largest cut from the original stone, Cullinan I, remains unmatched.

Weighing 530.2 carats
Pear-shaped, flawless in execution
Mounted in the Sovereign’s Sceptre
This is not just a diamond.
It is the pinnacle of gemstone achievement.

The second-largest stone, Cullinan II, holds equal significance.
Weighing 317.4 carats
Cushion-cut, balanced and commanding
Set in the Imperial State Crown
Together, Cullinan I and II form the core of British royal symbolism.
Perhaps the most fascinating pieces are the Cullinan III and IV.
Worn as a brooch
Often referred to as “Granny’s Chips” by Queen Elizabeth II
Representing extraordinary diamonds worn in a personal context
This reveals a unique truth:
even the largest diamonds can become part of daily identity at the highest level of royalty.
Unlike private collections, the Cullinan diamonds represent:
The power of an empire
The continuity of monarchy
The transformation of a natural wonder into cultural heritage
They are not owned in the traditional sense.
They are held in trust for history itself.
What makes the Cullinan story unparalleled is its totality:
Size beyond comparison
Cutting precision at the highest level
Integration into royal identity
It represents the absolute peak of what diamonds can achieve.
The Cullinan legacy teaches us that the rarest diamonds are not just exceptional—they become symbols that transcend generations, nations, and time itself.
At Legacy Diamonds and Gemstones, this is the ultimate benchmark—
to work with stones that are not just rare, but historically and emotionally irreplaceable.
