About this 1.9ct lab-grown princess diamond

This 1.9ct lab-grown princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG618453726 or 618453726. Listed at 19 retailers as of October 29, 2026, with prices from £172 to £993, a £821 spread on the same certified stone. Brilliant Earth lists it at £993. 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.
