About this 0.5ct natural cushion diamond

This 0.5ct natural cushion sits in the half to three-quarter carat band, graded H 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 1543954089. Listed at 15 retailers as of November 2, 2026, with prices from $605 to $1,514, a $909 spread on the same certified stone. MOH London lists it at $1,514. 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.
