About this 0.78ct natural marquise diamond

This 0.78ct natural marquise sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5131411226. Listed at 2 retailers as of November 2, 2026, with prices from $2,486 to $3,806, a $1,320 spread on the same certified stone. 77 Diamonds lists it at $3,806. 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.
