This 1.55ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG579362101 or 579362101. Listed at 11 retailers as of October 31, 2026, with prices from €236 to €1,364, a €1,128 spread on the same certified stone. Brilliant Earth lists it at €1,364. 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.
