About this 1.66ct natural cushion diamond

This 1.66ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1139604493. Listed at 21 retailers as of November 1, 2026, with prices from £6,291 to £10,636, a £4,346 spread on the same certified stone. MOH London lists it at £10,636. 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.
