About this 1.73ct natural heart diamond

This 1.73ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 2191291236. Listed at 2 retailers as of October 29, 2026, with a relatively tight 6% 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.
