About this 0.73ct natural cushion diamond

This 0.73ct 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 2181017535. Listed at 8 retailers as of October 28, 2026, with prices from £1,288 to £2,665, a £1,377 spread on the same certified stone. MOH London lists it at £2,665. 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.
