About this 1.03ct lab-grown heart diamond

This 1.03ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG774651349 or 774651349. Listed at 21 retailers as of October 30, 2026, with prices from £175 to £973, a £798 spread on the same certified stone. Reve Diamonds lists it at £973. 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.
