About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two 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 2245066342. Listed at 10 retailers as of October 30, 2026, with prices from $9,676 to $22,118, a $12,443 spread on the same certified stone. NZ Jewellers lists it at $22,118. 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.
