About this 0.8ct natural marquise diamond

This 0.8ct 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 3555215395. Listed at 7 retailers as of November 1, 2026, with prices from $1,361 to $3,587, a $2,227 spread on the same certified stone. Do Amore Diamonds lists it at $3,587. 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.
