About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded J 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 1423916763. Listed at 7 retailers as of November 6, 2026, with prices from £22,334 to £26,888, a £4,554 spread on the same certified stone. Jared lists it at £26,888. 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.
