The Aurora

My father ordered it and had it sent to my flat. It arrived when the tracking said it would. The facets are individually cut, and you can see where one meets the next if you hold it close, which he wanted me to check.

My wife had it sized at a 13 and gave it to me the morning of my class reunion. It went on without needing soap, which was not true of my last band. Two people at the table turned my hand to watch the colour move.

I bought this for my husband, who had worn a plain titanium band from Blue Nile for six years. The practical difference is that the titanium went invisible on his hand and this does not. The facets shift blue to violet when he turns it.

I found my old band in a drawer last month and put it on out of curiosity. It was thin, light and slid straight round. This one, a size 11, has been on daily for nine months and sits without turning.

I gave it six months, from our October wedding through winter, before deciding. The turn came when I noticed the facets had not gone milky at the contact points the way a coated ring does. That answered the only doubt I had.

Size 12, close at the base and over the knuckle without a fight. Under a desk lamp it reads deep blue with a violet edge only along the top row of facets, which is quieter than I had assumed.

A year of wear on a ring of about 15 grams. It has never rolled facet-down on my finger, and the cut peaks have taken a soft polish rather than chipping.

The colour shift looked like a lot on the first day. By the end of the week I had stopped catching it in my own eye line, and it now only shows when I turn my hand. The box held the ring, a sizing gauge and a cloth.

Given to me by my wife before my brother's rehearsal dinner. My old band was flat brushed grey and vanished under restaurant light; this one threw violet across the table when I reached for a glass. The facets are cut, not moulded.

My partner ordered it in a 12 and I did not commit to an opinion for three weeks. The moment was catching it against a grey coat sleeve, where the shift read as depth rather than a colour effect. It sits close at the base and has not moved since.

Wore it at our February wedding and the cut facets held light in an indoor ceremony where I had honestly expected them to go flat. Fair warning, the shift is much less obvious under fluorescent light.

I set this next to my old band on the bathroom counter and the old one looked like a washer. Size 11 in this, half up from the old 10.5, and it clears the knuckle where the old one had to be forced. The facets run at alternating angles rather than all one way.
