This 1.25ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG684503436 or 684503436. Listed at 20 retailers as of October 28, 2026, with prices from £177 to £982, a £804 spread on the same certified stone. Reve Diamonds lists it at £982. 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.
