About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556551357. Listed at 14 retailers as of November 4, 2026, with prices from ₹2,40,435 to ₹5,31,743, a ₹2,91,308 spread on the same certified stone. MOH London lists it at ₹5,31,743. 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.
