About this 0.37ct natural marquise diamond

This 0.37ct natural marquise sits in the sub-half-carat band, graded G 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 2566345679. Listed at 3 retailers as of November 1, 2026, with prices from $364 to $500, a $136 spread on the same certified stone. 77 Diamonds lists it at $500. 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.
