About this 1.01ct lab-grown princess diamond

This 1.01ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG849637283 or 849637283. Listed at 5 retailers as of November 5, 2026, with prices from £152 to £374, a £223 spread on the same certified stone. Michael Trio lists it at £374. 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.
