About this 0.66ct natural marquise diamond

This 0.66ct natural marquise sits in the half to three-quarter carat band, graded D 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 2557758018. Listed at 14 retailers as of October 31, 2026, with prices from $1,674 to $3,353, a $1,679 spread on the same certified stone. Flawless Fine Jewelry lists it at $3,353. 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.
