About this 3.02ct natural marquise diamond

This 3.02ct natural marquise sits in the three to five 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 1549572804. Listed at 10 retailers as of November 1, 2026, with prices from £30,132 to £39,661, a £9,528 spread on the same certified stone. The Diamond Guys lists it at £39,661. 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.
