0.42ct Round G SI1 GIA

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.

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 0.42 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.
