About this 1.58ct natural cushion diamond

This 1.58ct natural cushion sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6177585549. Listed at 6 retailers as of November 4, 2026, with prices from $4,762 to $7,040, a $2,278 spread on the same certified stone. 77 Diamonds lists it at $7,040. 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.
