This 1.51ct lab-grown princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG670419099 or 670419099. Listed at 19 retailers as of October 31, 2026, with prices from $242 to $1,803, a $1,562 spread on the same certified stone. Brilliant Earth lists it at $1,803. 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.
