About this 1.03ct natural marquise diamond

This 1.03ct 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 1508837337. Listed at 2 retailers as of November 5, 2026, with prices from $4,587 to $7,201, a $2,614 spread on the same certified stone. Diamond Quarter lists it at $7,201. 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.
