This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7456427957. Listed at 15 retailers as of November 6, 2026, with prices from $3,649 to $6,570, a $2,921 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,570. 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.
