About this 0.99ct lab-grown princess diamond

This 0.99ct lab-grown princess sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG630454820 or 630454820. Listed at a single retailer as of October 29, 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.
