About this 1.28ct lab-grown princess diamond

This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6491278103. Listed at 20 retailers as of October 27, 2026, with a 303% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
