About this 1.6ct lab-grown princess diamond

This 1.6ct lab-grown princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG447002188 or 447002188. Listed at 10 retailers as of November 1, 2026, with prices from $1,535 to $5,085, a $3,550 spread on the same certified stone. MOH London lists it at $5,085. 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.
