This 1.51ct natural round sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 1535202625. Listed at 17 retailers as of November 1, 2026, with prices from $4,128 to $9,137, a $5,008 spread on the same certified stone. NZ Jewellers lists it at $9,137. 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.
