About this 0.51ct lab-grown heart diamond

This 0.51ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847690779 or 847690779. Listed at 9 retailers as of October 26, 2026, with prices from £105 to £307, a £202 spread on the same certified stone. Friendly Diamonds lists it at £307. 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.
