About this 1.27ct lab-grown heart diamond

This 1.27ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG600346771 or 600346771. Listed at 6 retailers as of November 4, 2026, with prices from $252 to $1,198, a $946 spread on the same certified stone. Michael Trio lists it at $1,198. 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.
