About this 1.01ct natural marquise diamond

This 1.01ct 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 2245097453. Listed at 15 retailers as of November 4, 2026, with prices from $4,020 to $7,644, a $3,624 spread on the same certified stone. Helzberg Diamonds lists it at $7,644. 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.
