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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5241073881. Listed at 13 retailers as of November 1, 2026, with prices from £15,958 to £25,716, a £9,757 spread on the same certified stone. Helzberg Diamonds lists it at £25,716. 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.
