About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1425646526. Listed at 11 retailers as of October 30, 2026, with prices from ₹3,35,363 to ₹4,83,310, a ₹1,47,946 spread on the same certified stone. 77 Diamonds lists it at ₹4,83,310. 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.
