This 1ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840640103 or 840640103. Listed at 13 retailers as of November 6, 2026, with prices from $300 to $1,461, a $1,161 spread on the same certified stone. Reve Diamonds lists it at $1,461. 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.
