About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6532650427. Listed at 18 retailers as of October 27, 2026, with prices from $1,325 to $3,505, a $2,180 spread on the same certified stone. NZ Jewellers lists it at $3,505. 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.
