About this 0.73ct lab-grown heart diamond

This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG837641636 or 837641636. Listed at 10 retailers as of November 1, 2026, with prices from £138 to £809, a £671 spread on the same certified stone. Reve Diamonds lists it at £809. 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.
