About this stone
1.31ct round brilliant diamond. D colour, VVS1 clarity, excellent cut. GIA certified, report 1558144456.
What these grades mean on the finger
Graded D, this stone sits in the colourless band, the top of the GIA scale. Face-up it reads icy white in any metal, and the difference between it and the grades just below is paper-thin to the naked eye.
VVS1 clarity: the inclusions are so small a trained grader needs magnification and patience to find them. To the naked eye this stone is immaculate.
At 1.31 carats, a well-cut round of this weight faces up at roughly 6.9 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

- 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 7.05 mm, within 2.5% of the 6.91 mm estimate derived from our sample for this shape and scaled to this weight. Compare its width and proportions as well.
The report records 61.2% depth. Read this alongside the cut grade, table, crown and pavilion proportions; depth alone does not establish light performance.
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.
