About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567682851. Listed at 15 retailers as of October 30, 2026, with prices from £6,964 to £12,967, a £6,003 spread on the same certified stone. NZ Jewellers lists it at £12,967. 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.
