This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG823647457 or 823647457. Listed at 2 retailers as of October 30, 2026, with prices from $302 to $636, a $334 spread on the same certified stone. 77 Diamonds lists it at $636. 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.
