About this 0.48ct natural marquise diamond

This 0.48ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2121949828. Listed at 2 retailers as of October 29, 2026, with prices from £431 to £653, a £223 spread on the same certified stone. Yorxs lists it at £653. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
