About this stone
1.03ct natural round brilliant diamond, G colour and VS2 clarity. Excellent cut. GIA report 2566142945. Confirm current availability with the Bedfordview desk.
What these grades mean on the finger
Graded G, near-colourless: to the naked eye it faces up white, and most buyers cannot tell it from a colourless grade once it is set. The saving over a D to F stone is real; the visible difference rarely is.
VS2 clarity: clean to the naked eye, with inclusions visible only under the loupe. The sweet spot where the certificate price drops but the face-up view does not.
At 1.03 carats, a well-cut round of this weight faces up at roughly 6.4 mm across. Cut quality decides how big it looks from across the table, which is why the cut grade matters more than the weight.
Graded by GIA, the laboratory that wrote the 4Cs. The original report travels with the stone and is independently verifiable on GIA Report Check before you pay a cent.
Provenance
- Prodiam sells diamonds cut at Procut DCW and diamonds sourced polished through the trade. Ask the desk to confirm the route and available provenance records for this individual stone.
- A grading report records the diamond's characteristics. It does not by itself establish where the diamond was mined or who cut it.

Measurements and price context
Read this diamond's report alongside the dated comparison samples below. Measurements and price guides help frame a viewing; they do not replace one.
Its longest face-up measurement is 6.57 mm, within 2.5% of the 6.43 mm estimate derived from our sample for this shape and scaled to this weight. Compare its width and proportions as well.
The report records 60% depth. Read this alongside the cut grade, table, crown and pavilion proportions; depth alone does not establish light performance.
For broad price context, our 8 September 2026 sample of 0.95–1.09 ct G-colour stones at VS1–VS2 clarity, with an Excellent cut filter and no fluorescence, had a median asking price of R68 800; the middle half was R62 500–R76 300, including VAT and loose-stone delivery. This sample is not matched to every characteristic of this diamond and is not its valuation. Confirm the individual stone's current quote with the desk.
Dimension estimates use a sample of 5 078 sourced listings captured 25 August 2026, scaled to this stone's weight. They are estimates, not a cut grade.
