This 0.53ct natural radiant sits in the half to three-quarter 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 5221166759. Listed at 2 retailers as of November 6, 2026, with prices from $832 to $1,295, a $463 spread on the same certified stone. 77 Diamonds lists it at $1,295. 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.
