About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 170001491060. Listed at 5 retailers as of November 6, 2026, with prices from $3,640 to $4,937, a $1,297 spread on the same certified stone. Yorxs lists it at $4,937. 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.
