The Etoile is Tiffany's band-style engagement ring: a plain platinum band set with a single round brilliant diamond, here 0.30 ct in F color and VVS1 clarity. It is a minimal, low-profile design rather than a halo or solitaire with a raised head. The best new price is $2,250 at The Diamond Oak as of November 4, 2026, the only new listing found. That is well below Tiffany's own retail for a comparable Etoile, which is the main reason to consider this listing.
Owners of the Etoile line praise its understated look and everyday comfort, and Tiffany diamonds are generally regarded as well cut. The common complaint about small-carat Etoile rings is that the stone looks smaller in person than in photos.
