This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839611382 or 839611382. Listed at 20 retailers as of November 4, 2026, with prices from $359 to $2,015, a $1,655 spread on the same certified stone. Reve Diamonds lists it at $2,015. 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.
