About this 1.57ct natural radiant diamond

This 1.57ct 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 GIA 6552746081. Listed at 2 retailers as of November 5, 2026, with prices from $5,095 to $6,113, a $1,017 spread on the same certified stone. Blue Nile lists it at $6,113. 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.
