Gemstone Eternity Bands: Sapphire, Emerald and Amethyst

Oct 7

2 min read

A coloured eternity band is the most striking way to wear a gemstone every day, and the hardest to get wrong — there is no centre stone to judge, only the quality of the matching across the line.

The one thing to check before buying

Full eternity bands usually cannot be resized. Stones run the entire circumference, so there is no plain metal to cut and rejoin. If your size may change, or you are buying as a surprise, choose a half eternity instead — the stones cover the top half and the plain back allows resizing.

Which stone suits daily wear

Sapphire rates 9 on the Mohs scale, second only to diamond, and handles daily wear indefinitely
Emerald rates 7.5 to 8 and is often oil-treated, so it suits regular wear with care
Amethyst rates 7, fine for regular wear, though prolonged sunlight can fade the colour over years
Aquamarine rates 7.5 to 8, durable enough for everyday use

On a band, which knocks against desks and door handles more than a pendant ever does, hardness matters more than it would elsewhere.

Matching matters more than carat weight

On a single-stone ring you judge the stone. On an eternity band you judge the consistency: twenty stones of slightly different tone look wrong in a way one stone never can. That matching is most of the work and most of the cost.
