Graff to debut the Infinity Tiara in Japan


Showcasing the largest heart shape diamond in the world

To celebrate the opening of the House’s flagship store in Ginza, in November Graff will unveil for the first time the extraordinary Infinity Tiara.

An intricately crafted, incredibly complex design that swirls skywards in spirals of scintillation, the tiara is all the more magnificent for its crowning glory: the record-breaking Infinity diamond.

The 373 carat diamond

The heart shape Infinity diamond was cut and polished by Graff from the 373 carat rough diamond discovered at the Karowe Mine in Botswana.

Uncovered at the same mine as the legendary 1,109 carat Lesedi La Rona diamond, when the 373 carat stone and the Lesedi La Rona were placed side by side, it was found their contours fit together perfectly, supporting the theory that they once formed
part of an even larger diamond.

Analysing the rough diamond

Revealing The Infinity diamond took many months of undivided expert attention. Before
the first cut could be made, Graff’s experts examined the 373 carat diamond from deep
within, mapping its precise structure and identifying the tiniest of flaws.

The analysis revealed that a heart shape diamond was hidden inside, the magnitude of
which had never been seen before.

Polishing the heart shape

A master cutter with more than 40 years’ experience was tasked with transforming the 373 carat diamond.

The heart shape is among Graff’s most iconic diamond cuts and one of the most difficult to master. This epic challenge was made even more daunting by the sheer size of the rough

Graff’s master cutter finessed the polished diamond until it was completely symmetrical, with an impeccably sharp point, flawless facets and aesthetically beautiful cleft, which took six weeks alone to refine. After more than a year, the diamond was ready to be unveiled.

Making diamond history

A triumph of diamond mastery, the heart shape diamond was an exquisite marriage of brilliance and beauty.

Certified by the GIA as D colour, VVS1 clarity and weighing an astonishing 157.80 carats, it was officially the largest heart shape diamond in the world.

In honour of the Graff family’s infinite love of diamonds, the record-setting stone was named The Infinity.
