About this 1.21ct lab-grown radiant diamond

This 1.21ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840640263 or 840640263. Listed at 15 retailers as of October 31, 2026, with prices from ₹27,061 to ₹2,21,234, a ₹1,94,173 spread on the same certified stone. Brilliant Earth lists it at ₹2,21,234. 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.
