This 1.05ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG818671056 or 818671056. Listed at 19 retailers as of October 30, 2026, with prices from $299 to $1,727, a $1,429 spread on the same certified stone. Reve Diamonds 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.
