About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566652461. Listed at 3 retailers as of November 1, 2026, with a relatively tight 7% 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.
