About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 801638806. Listed at 19 retailers as of October 30, 2026, with prices from £5,288 to £10,680, a £5,392 spread on the same certified stone. NZ Jewellers lists it at £10,680. 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.
