About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 200000048476. Listed at 3 retailers as of November 2, 2026, with prices from $3,212 to $5,124, a $1,912 spread on the same certified stone. MOH London lists it at $5,124. 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.
