About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830620137 or 830620137. Listed at 6 retailers as of October 29, 2026, with prices from ₹40,680 to ₹2,41,986, a ₹2,01,306 spread on the same certified stone. Brilliant Earth lists it at ₹2,41,986. 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.
