About this 4.2ct lab-grown princess diamond

This 4.2ct lab-grown princess sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG575369889 or 575369889. Listed at 15 retailers as of October 31, 2026, with prices from $1,053 to $5,210, a $4,157 spread on the same certified stone. Brilliant Earth lists it at $5,210. 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.
