■ The catch — co-equal billing, always
It can never be resized. Stones run the full 360°, so the size you order is the size forever — get sized professionally in a stable-temperature window, and go half a size up if you run hot.
Dealbreaker? The Sienna half-eternity keeps the sparkle and stays resizable ↓

Traps — this verdict avoids
The no-resize trap
Full-eternity bands have stones all the way around and can never be resized — half-eternity and plain bands adjust only 1-2 sizes. Order a half-size up if you live somewhere hot or expect knuckle swelling.
Fake forever metals
Gold-plated and vermeil rings are not lifetime jewelry — plating wears off in 1-3 years on rings. Amazon sub-$300 'eternity' rings are typically CZ, moissanite, or 10k gold — verify the metal stamp and stone type before buying.
Micro-pavé stone loss
Micro-pavé bands under 1.5mm wide lose stones more easily than channel or shared-prong settings — bezel and channel are the two safest for active hands. Have any pavé band checked by a jeweler annually.
