About this 1.55ct natural heart diamond

This 1.55ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231706220. Listed at 8 retailers as of October 31, 2026, with a relatively tight 12% 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.
