About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565061714. Listed at 14 retailers as of November 4, 2026, with prices from $4,137 to $7,656, a $3,519 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,656. 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.
