This 1.53ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGG1202217. Listed at 6 retailers as of November 4, 2026, with prices from £195 to £891, a £696 spread on the same certified stone. Taylor and Hart lists it at £891. 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.
