This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG817618207 or 817618207. Listed at 12 retailers as of November 1, 2026, with prices from £133 to £797, a £663 spread on the same certified stone. Reve Diamonds lists it at £797. 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.
