About this 1.01ct lab-grown heart diamond

This 1.01ct 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 LG647429820 or 647429820. Listed at 6 retailers as of October 26, 2026, with prices from €1,088 to €2,083, a €995 spread on the same certified stone. MOH London lists it at €2,083. 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.
