About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414059737 or 414059737. Listed at 10 retailers as of November 5, 2026, with prices from €546 to €3,205, a €2,659 spread on the same certified stone. MOH London lists it at €3,205. 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.
