About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562373069. Listed at 6 retailers as of October 31, 2026, with prices from ₹2,25,972 to ₹3,21,112, a ₹95,141 spread on the same certified stone. Blue Nile lists it at ₹3,21,112. 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.
