About this 1.62ct natural round diamond

This 1.62ct natural round sits in the one-and-a-half to two carat band, graded N colour (tinted) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI 478197843. Listed at 5 retailers as of November 5, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
