This 0.51ct lab-grown princess sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843689211 or 843689211. Listed at 8 retailers as of October 29, 2026, with prices from $420 to $1,636, a $1,215 spread on the same certified stone. MOH London lists it at $1,636. 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.
