About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-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 7552847151. Listed at 3 retailers as of October 30, 2026, with prices from $284 to $411, a $127 spread on the same certified stone. 77 Diamonds lists it at $411. 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.
