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 1448393702. Listed at 10 retailers as of October 31, 2026, with prices from ₹2,80,979 to ₹4,19,495, a ₹1,38,516 spread on the same certified stone. 77 Diamonds lists it at ₹4,19,495. 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.
