About this stone
0.41ct round brilliant diamond. F colour, SI1 clarity, excellent cut. GIA certified, report 2528810358.
What these grades mean on the finger
Graded F, 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.
SI1 clarity: small inclusions a loupe will find. At this size most SI1 stones are eye-clean, and we confirm that on the bench loupe before you commit.
At 0.41 carats, a well-cut round of this weight faces up at roughly 4.8 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.
