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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5181153321. Listed at 5 retailers as of October 27, 2026, with prices from $1,712 to $3,022, a $1,310 spread on the same certified stone. Wholesale Diamonds Direct lists it at $3,022. 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.
