About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG440020546 or 440020546. Listed at 8 retailers as of October 25, 2026, with prices from $2,255 to $4,448, a $2,193 spread on the same certified stone. Flawless Fine Jewelry lists it at $4,448. 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.
