About this 0.34ct natural marquise diamond

This 0.34ct natural marquise sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556840655. Listed at 3 retailers as of October 29, 2026, with prices from $336 to $454, a $118 spread on the same certified stone. 77 Diamonds lists it at $454. 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.
