About this 0.64ct natural marquise diamond

This 0.64ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231445809. Listed at 4 retailers as of October 31, 2026, with prices from $1,570 to $2,354, a $785 spread on the same certified stone. 77 Diamonds lists it at $2,354. 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.
