About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded E 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 6555621242. Listed at 15 retailers as of October 27, 2026, with prices from $460 to $1,936, a $1,476 spread on the same certified stone. NZ Jewellers lists it at $1,936. 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.
