About this 1.03ct lab-grown heart diamond

This 1.03ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849602173 or 849602173. Listed at 15 retailers as of November 4, 2026, with prices from £129 to £779, a £650 spread on the same certified stone. Reve Diamonds lists it at £779. 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.
