About this 0.72ct natural heart diamond

This 0.72ct natural heart sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2126166221. Listed at 5 retailers as of November 2, 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.
