About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407945556 or 407945556. Listed at 10 retailers as of November 5, 2026, with prices from $888 to $5,512, a $4,624 spread on the same certified stone. MOH London lists it at $5,512. 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.
