About this 0.74ct natural cushion diamond

This 0.74ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6521180520. Listed at 3 retailers as of October 29, 2026, with prices from £533 to £670, a £137 spread on the same certified stone. Blue Nile lists it at £670. 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.
