About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7438374065. Listed at 13 retailers as of November 2, 2026, with prices from $2,069 to $5,803, a $3,734 spread on the same certified stone. Moon Ocean lists it at $5,803. 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.
