About this 0.7ct natural cushion diamond

This 0.7ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6412965521. Listed at 13 retailers as of November 1, 2026, with prices from £478 to £1,185, a £707 spread on the same certified stone. MOH London lists it at £1,185. 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.
