About this 1.58ct natural heart diamond

This 1.58ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5513449840. Listed at a single retailer as of October 31, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
