About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded H colour (near-colourless) and I1 clarity (included), with a top-tier cut grade and certified by GSI. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically.
