About this 1.09ct lab-grown heart diamond

This 1.09ct lab-grown heart sits in the classic one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG823642235 or 823642235. Listed at 13 retailers as of November 4, 2026, with prices from $235 to $1,361, a $1,126 spread on the same certified stone. MOH London lists it at $1,361. 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.
