About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-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 6562645742. Listed at 13 retailers as of November 5, 2026, with prices from $4,329 to $8,720, a $4,391 spread on the same certified stone. Wholesale Diamonds Direct lists it at $8,720. 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.
