About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532770961. Listed at 22 retailers as of October 30, 2026, with prices from $9,737 to $22,113, a $12,376 spread on the same certified stone. NZ Jewellers lists it at $22,113. 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.
