This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6382782765. Listed at 5 retailers as of November 6, 2026, with prices from $2,081 to $3,093, a $1,012 spread on the same certified stone. 77 Diamonds lists it at $3,093. 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.
