About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545984395. Listed at 2 retailers as of November 5, 2026, with prices from £18,903 to £32,653, a £13,750 spread on the same certified stone. Diamonds Direct lists it at £32,653. 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.
