About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2507820366. Listed at 6 retailers as of November 4, 2026, with prices from $3,703 to $5,631, a $1,928 spread on the same certified stone. 77 Diamonds lists it at $5,631. 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.
