About this 0.39ct natural marquise diamond

This 0.39ct 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 5566376652. Listed at 3 retailers as of November 1, 2026, with prices from $477 to $615, a $138 spread on the same certified stone. 77 Diamonds lists it at $615. 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.
