About this 2.61ct natural round diamond

This 2.61ct natural round sits in the two to three carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by GIA 1236922138. 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.
