About this 1.23ct lab-grown princess diamond

This 1.23ct lab-grown princess sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG707543018 or 707543018. Listed at 12 retailers as of October 26, 2026, with prices from $185 to $1,085, a $900 spread on the same certified stone. MOH London lists it at $1,085. 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.
