About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545346290. Listed at 18 retailers as of October 28, 2026, with prices from ₹3,62,025 to ₹8,40,737, a ₹4,78,712 spread on the same certified stone. Queensmith lists it at ₹8,40,737. 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.
