About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000040777. Listed at 3 retailers as of November 3, 2026, with prices from $2,714 to $6,622, a $3,908 spread on the same certified stone. NZ Jewellers lists it at $6,622. 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.
