About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000115632. Listed at 8 retailers as of November 5, 2026, with prices from $5,189 to $9,795, a $4,606 spread on the same certified stone. NZ Jewellers lists it at $9,795. 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.
