This 0.77ct 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 LG848666364 or 848666364. Listed at 7 retailers as of October 27, 2026, with prices from $273 to $859, a $585 spread on the same certified stone. Taylor and Hart lists it at $859. 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.
