This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838656698 or 838656698. Listed at 2 retailers as of October 28, 2026, with prices from £136 to £275, a £139 spread on the same certified stone. 77 Diamonds lists it at £275. 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.
