About this 0.43ct natural marquise diamond

This 0.43ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5553822233. Listed at 3 retailers as of November 2, 2026, with prices from £358 to £413, a £55 spread on the same certified stone. 77 Diamonds lists it at £413. 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.
