This 3.5ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821656739 or 821656739. Listed at 8 retailers as of November 2, 2026, with prices from £1,848 to £6,356, a £4,508 spread on the same certified stone. With Clarity lists it at £6,356. 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.
