About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565596105. Listed at 12 retailers as of November 4, 2026, with prices from $5,374 to $9,598, a $4,224 spread on the same certified stone. Wholesale Diamonds Direct lists it at $9,598. 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.
