About this 1.66ct natural round diamond

This 1.66ct natural round sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 1102520136. Listed at 6 retailers as of October 31, 2026, with a relatively tight 15% 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.
