About this 1.03ct lab-grown princess diamond

This 1.03ct lab-grown princess sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG853694591 or 853694591. Listed at 11 retailers as of November 5, 2026, with prices from $269 to $1,156, a $888 spread on the same certified stone. Brilliant Earth lists it at $1,156. 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.
