About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG842658717 or 842658717. Listed at 17 retailers as of October 27, 2026, with prices from $578 to $2,974, a $2,396 spread on the same certified stone. Queensmith lists it at $2,974. 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.
