Is $2,250 a good price for this ring?

It is the only new price found, at The Diamond Oak as of November 4, 2026. Tiffany retail for a 0.30 ct Etoile is typically higher, so this is a discount to boutique pricing, but compare against other Etoile listings before committing.

Is 0.30 ct too small for an engagement ring?

It is on the small side, and the Etoile's flush band makes it look smaller than a raised solitaire of the same weight. It suits buyers who want a subtle ring or have a small finger size.

Can a size 4.25 ring be resized?

Yes, a plain platinum band like this can usually be resized by one or two sizes. Have a jeweler confirm the setting allows it before you buy.

What does F VVS1 mean?

F means colorless and VVS1 means very, very slightly included, so any flaws are hard to see under magnification. Ask for the grading report or an independent appraisal to confirm it.

Does it come with Tiffany packaging and papers?

That depends on the seller, not the model. Ask The Diamond Oak whether the box, certificate and any Tiffany paperwork are included before you buy.

How does Etoile compare to the Tiffany Setting solitaire?

The Etoile sets the diamond into the band, while the Tiffany Setting raises it in a six-prong head. The solitaire shows more of the stone; the Etoile is lower and less likely to snag.
