This 1.02ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG850679578 or 850679578. Listed at 5 retailers as of November 2, 2026, with prices from $422 to $1,172, a $750 spread on the same certified stone. MOH London lists it at $1,172. 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.
