About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551449414. Listed at 15 retailers as of November 2, 2026, with prices from ₹2,77,909 to ₹6,24,303, a ₹3,46,394 spread on the same certified stone. MOH London lists it at ₹6,24,303. 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.
