About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1373888157. Listed at 21 retailers as of October 31, 2026, with prices from £7,646 to £13,592, a £5,946 spread on the same certified stone. MOH London lists it at £13,592. 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.
