About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded G 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 6545048687. Listed at 9 retailers as of November 4, 2026, with prices from $2,551 to $5,504, a $2,953 spread on the same certified stone. MOH London lists it at $5,504. 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.
