About this 1.71ct lab-grown heart diamond

This 1.71ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG724507544 or 724507544. Listed at 8 retailers as of October 28, 2026, with prices from £308 to £918, a £611 spread on the same certified stone. MOH London lists it at £918. 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.
