About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI 234651662. Listed at 3 retailers as of November 5, 2026, with prices from $3,523 to $5,019, a $1,496 spread on the same certified stone. Yorxs lists it at $5,019. 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.
