About this 1.46ct lab-grown heart diamond

This 1.46ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG836612327 or 836612327. Listed at 19 retailers as of October 30, 2026, with prices from £184 to £1,029, a £845 spread on the same certified stone. Brilliant Earth lists it at £1,029. 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.
