About this 0.51ct natural cushion diamond

This 0.51ct 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 5523919294. Listed at 25 retailers as of November 6, 2026, with prices from $682 to $2,032, a $1,350 spread on the same certified stone. MOH London lists it at $2,032. 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.
