This 0.55ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG837656468 or 837656468. Listed at 16 retailers as of October 27, 2026, with prices from £143 to £871, a £728 spread on the same certified stone. Reve Diamonds lists it at £871. 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.
