About this 3.02ct natural cushion diamond

This 3.02ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559582620. Listed at 17 retailers as of November 4, 2026, with prices from $30,446 to $54,769, a $24,323 spread on the same certified stone. MOH London lists it at $54,769. 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.
