About this 0.67ct natural marquise diamond

This 0.67ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5231971808. Listed at 3 retailers as of November 2, 2026, with prices from $1,926 to $3,064, a $1,138 spread on the same certified stone. MOH London lists it at $3,064. 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.
