About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded H 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 5436497455. Listed at 20 retailers as of October 29, 2026, with prices from ₹2,91,089 to ₹6,36,790, a ₹3,45,701 spread on the same certified stone. MOH London lists it at ₹6,36,790. 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.
