This 1.13ct 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 LG757507435 or 757507435. Listed at 19 retailers as of October 30, 2026, with prices from £137 to £1,314, a £1,176 spread on the same certified stone. Do Amore Diamonds lists it at £1,314. 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.
