About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2524593492. Listed at 3 retailers as of November 4, 2026, with prices from $5,407 to $7,218, a $1,811 spread on the same certified stone. Yorxs lists it at $7,218. 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.
