About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded I 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 2241097416. Listed at 11 retailers as of November 5, 2026, with prices from $3,528 to $6,509, a $2,981 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,509. 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.
