About this 0.98ct natural marquise diamond

This 0.98ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6157228140. Listed at 4 retailers as of November 1, 2026, with prices from $3,888 to $7,263, a $3,375 spread on the same certified stone. MOH London lists it at $7,263. 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.
