About this 0.85ct lab-grown princess diamond

This 0.85ct lab-grown princess sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840632603 or 840632603. Listed at 18 retailers as of October 30, 2026, with prices from £174 to £970, a £796 spread on the same certified stone. Reve Diamonds lists it at £970. 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.
