About this 1.47ct lab-grown heart diamond

This 1.47ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG774635436 or 774635436. Listed at 18 retailers as of October 30, 2026, with prices from £193 to £1,030, a £838 spread on the same certified stone. Reve Diamonds lists it at £1,030. 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.
