This 1.5ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG801626387 or 801626387. Listed at 16 retailers as of October 30, 2026, with prices from €181 to €1,075, a €894 spread on the same certified stone. Reve Diamonds lists it at €1,075. 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.
