Founding, later ownership and individual design dates describe different events. Named objects and manufacturer material claims retain their stated scope.

A London house with a twentieth-century beginning
Graff's own history identifies Laurence Graff as the founder of the London company in 1960. Its account centres on diamonds and on the people choosing and working with them. This is a relatively recent house history beside the nineteenth-century origins of several other jewellery makers; a shorter chronology does not by itself explain the character of a finished jewel.
The current house account presents stone selection and the stages of production as activities involving successive generations of the Graff family. Read that as the manufacturer's description of its approach. It is useful evidence about how the house wishes its work to be understood, while leaving room to examine a particular stone, setting or design on its own terms.
Evidence: The House of Graff, This is Graff
Founding date and registered company date
Graff's website terms name Graff Diamonds Limited as the operator. The Companies House overview for company 00678883 records incorporation on 23 December 1960 and an active private limited company at the date checked. The heritage year and the precise incorporation date therefore answer related, but different, questions.
Neither entry supplies a complete account of the international group or every company's shareholders. Family participation described on the house website is not a quantified ownership statement. This profile consequently keeps a complete current share register unknown. That separation is helpful when reading any jewellery business: identify the brand's history, the named website operator and the exact company record before assuming that one name explains every activity or legal relationship.

Describe the diamond before the reputation
GIA's four quality factors—colour, clarity, cut and carat weight—provide a vocabulary for a diamond that remains useful whatever name appears on its setting. Carat is a unit of mass; one metric carat is 0.2 grams. A large weight does not settle the other three factors, and a memorable house story does not substitute for information about an individual stone.
Cut needs particular care because the word can refer to a fashioned shape as well as to how facets and proportions interact with light. GIA includes the emerald cut among named fancy shapes. In a Graff description, therefore, an emerald-cut diamond is a diamond in that cutting form, not an emerald. Separating material identity from cutting language prevents an attractive collection name from becoming a gemmological misunderstanding.
Evidence: Diamond Quality Factors
A different rhythm of light
Graff describes emerald-cut diamonds through their angular facets and mirror-like appearance, contrasting their subtler scintillation with brilliant-cut stones. These are the manufacturer's design terms, rather than a universal performance ranking. They suggest where to direct attention: broad changes of light, repeated edges and the relationship between the outline and the interior.
Try describing that rhythm before deciding whether it is better or worse than another cutting style. A shape can suit a composition because it echoes a metal edge or contrasts with surrounding stones. That is an aesthetic relationship, distinct from a laboratory judgement about the diamond. The useful question is not which shape wins, but what role the chosen shape plays in the particular jewel in front of you.

Lesedi La Rona: acquisition and transformation
Graff's announcement labelled September 2017 describes acquiring the 1,109-carat Lesedi La Rona rough diamond from Lucara Diamond Corp and identifies the Karowe mine in Botswana. A separate Graff account reports a 302.37-carat finished diamond and more than eighteen months of craftsmanship. Together the pages document a manufacturer's story about acquiring material and giving a major stone its finished form.
The two weights refer to different stages. They should not be presented as interchangeable measures of the same finished object, or used here to infer the total output of every cutting decision. Graff makes exceptional grading and record claims for the polished stone; this profile has not examined its individual GIA report or established a current worldwide ranking. The documented transformation is enough to study without turning a dated promotional superlative into a permanent fact.

From an important stone to wearable jewellery
Graff's account of making diamond earrings describes its Mayfair atelier, traditional goldsmithing tools used alongside modern equipment, and many pieces receiving more than one hundred hours of work. The wording matters: many is not every, and a workshop duration is not a grading category for a gemstone.
The account also encourages attention beyond the headline stone. A jewel has a composition and a metal structure as well as precious material. When looking at earrings, ask how the two pieces relate and where the visual emphasis falls. Those questions do not reveal the hidden construction or prove a manufacturer's claim, but they make the finished jewellery legible as a designed object rather than simply a list of carat weights.
A motif can be outlined or filled
The current Butterfly catalogue offers another entry into Graff, away from a single famous diamond. It identifies a butterfly-inspired collection and lists both silhouette and pavé variations. The motif provides a recurring subject, while those names invite attention to how the surface is organised.
An outline and a densely filled area can suggest the same subject in different ways. One directs the eye around a boundary; the other draws attention across a surface. That comparison is an editorial way of reading the catalogue, not a claim that all pieces share one construction or date. Look at a specific reference before carrying its materials or details across the whole collection. Nada's diamond and emerald articles make useful companions when separating the motif, the cut name and the actual gemstone.
Evidence: Butterfly
Looking study: silhouette, surface and focal point
Picture two simple geometric forms with the same outline: leave one open and fill the other with a pattern of small dots. Decide where your eye enters each form and whether the boundary or the surface attracts more attention. Now add one larger dot. Does the composition gain a focal point, or become harder to balance?
Use these questions to describe a piece of jewellery without borrowing a manufacturer's superlatives. Keep three notes separate: what you can see, what the maker says and what a gem report would need to establish. This original exercise concerns composition and evidence, not a recreation of a Graff jewel or a valuation.
