About this 1.02ct lab-grown heart diamond

This 1.02ct 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 LG842661036 or 842661036. Listed at 16 retailers as of November 4, 2026, with prices from £130 to £783, a £654 spread on the same certified stone. Reve Diamonds lists it at £783. 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.
