About this 1.28ct lab-grown cushion diamond

This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840622511 or 840622511. Listed at 17 retailers as of October 28, 2026, with prices from ₹40,204 to ₹2,58,182, a ₹2,17,978 spread on the same certified stone. Brilliant Earth lists it at ₹2,58,182. 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.
