About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1528588390. Listed at 12 retailers as of October 31, 2026, with prices from €4,377 to €6,436, a €2,059 spread on the same certified stone. Do Amore Diamonds lists it at €6,436. 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.
