About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555370030. Listed at 5 retailers as of October 30, 2026, with prices from ₹58,007 to ₹74,125, a ₹16,118 spread on the same certified stone. Blue Nile lists it at ₹74,125. 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.
