This 1.58ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849668496 or 849668496. Listed at 9 retailers as of October 27, 2026, with prices from $474 to $1,727, a $1,253 spread on the same certified stone. Brilliance lists it at $1,727. 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.
