About this 1.23ct lab-grown princess diamond

This 1.23ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG631470521 or 631470521. Listed at 3 retailers as of October 29, 2026, with a relatively tight 2% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
