About this 0.4ct lab-grown heart diamond

This 0.4ct lab-grown heart sits in the sub-half-carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG847661864 or 847661864. Listed at 7 retailers as of October 26, 2026, with prices from £96 to £606, a £509 spread on the same certified stone. MOH London lists it at £606. 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.
