About this 1.17ct lab-grown radiant diamond

This 1.17ct 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 LG634437781 or 634437781. Listed at 22 retailers as of October 29, 2026, with prices from $286 to $2,864, a $2,577 spread on the same certified stone. Brilliant Earth lists it at $2,864. 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.
