About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG798603661 or 798603661. Listed at 19 retailers as of October 27, 2026, with prices from €149 to €973, a €824 spread on the same certified stone. Reve Diamonds lists it at €973. 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.
