About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555305528. Listed at 20 retailers as of November 4, 2026, with prices from ₹3,82,254 to ₹8,08,350, a ₹4,26,095 spread on the same certified stone. MOH London lists it at ₹8,08,350. 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.
