About this 0.78ct natural marquise diamond

This 0.78ct 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 2245079755. Listed at 3 retailers as of November 1, 2026, with prices from $1,887 to $3,002, a $1,114 spread on the same certified stone. MOH London lists it at $3,002. 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.
