This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837624406 or 837624406. Listed at 21 retailers as of October 23, 2026, with prices from $155 to $1,050, a $895 spread on the same certified stone. Reve Diamonds lists it at $1,050. 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.
