This 1.99ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG823652393 or 823652393. Listed at 3 retailers as of October 29, 2026, with prices from £232 to £472, a £240 spread on the same certified stone. 77 Diamonds lists it at £472. 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.
