About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2568696492. Listed at 17 retailers as of October 30, 2026, with prices from $654 to $2,759, a $2,105 spread on the same certified stone. NZ Jewellers lists it at $2,759. 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.
