I love my diamond eternity ring (which I chose myself after about 15 years wed & 2 children) and wear it every day. I used to wear my wedding, engagement & eternity rings together, but after a finger infection had to stop wearing them for a month or so, & after that discovered I didn’t like multiple rings on my finger anymore so the eternity ring (being my favourite) was chosen & the others are still in my china ring dish on the bedside table!
I’d always wanted an emerald ring & DH gave me the money to choose my own 3 years ago for our 30th anniversary, I wear it all the time on my right hand, it’s the engagement ring I’d have liked but we couldn’t afford 35 years ago!
