About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545587837. Listed at 11 retailers as of November 4, 2026, with prices from $2,822 to $5,114, a $2,292 spread on the same certified stone. Wholesale Diamonds Direct lists it at $5,114. 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.
