About this 0.3ct natural marquise diamond

This 0.3ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551661709. Listed at 10 retailers as of October 31, 2026, with prices from $530 to $1,513, a $984 spread on the same certified stone. 18carati lists it at $1,513. 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.
