About this 0.53ct lab-grown heart diamond

This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG850695708 or 850695708. Listed at 3 retailers as of October 29, 2026, with prices from £278 to £544, a £266 spread on the same certified stone. Taylor and Hart lists it at £544. 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.
