About this 1.2ct lab-grown princess diamond

This 1.2ct lab-grown princess sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG662420639 or 662420639. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
