About this 0.33ct natural marquise diamond

This 0.33ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556920727. Listed at 4 retailers as of October 29, 2026, with prices from $434 to $581, a $147 spread on the same certified stone. 77 Diamonds lists it at $581. 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.
