This 8.51ct lab-grown princess sits in the over five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589390518 or 589390518. Listed at 13 retailers as of October 29, 2026, with prices from $1,460 to $5,590, a $4,130 spread on the same certified stone. Brilliant Earth lists it at $5,590. 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.
