About this 1.2ct lab-grown princess diamond

This 1.2ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG550237694 or 550237694. Listed at 2 retailers as of October 29, 2026, with prices from $422 to $1,221, a $799 spread on the same certified stone. Michael Trio lists it at $1,221. 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.
