About this 1.58ct lab-grown princess diamond

This 1.58ct lab-grown princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG12859715 or 12859715. Listed at 8 retailers as of October 27, 2026, with a relatively tight 18% 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.
