About this 2.51ct lab-grown princess diamond

This 2.51ct lab-grown princess sits in the two to three carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG514280881 or 514280881. Listed at 5 retailers as of October 29, 2026, with prices from £460 to £1,136, a £675 spread on the same certified stone. MOH London lists it at £1,136. 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.
