Any ring will deglove you.
I have a titanium ring (£22 from ebay), my brother has the same. Really pleased with them, we don’t really do jewelery so didn’t want to spend too much in case we didn’t get along with them but these have been great. It is a 4mm Court Shaped one from elma.jewellery.ltd my brother has bigger fingers and got a 6mm one. Find out your abc size from any high street jeweller.
I do remember looking at £2K Platinum rings on the high street, then I mentioned titanium and this poncey jeweller said they tarnish! He was just gutted that they look like platinum but are so cheap. He did then start to mention a ‘metal’ called Palladium…. all I could think of was Jimmy Tarbuck and the Royal Variety Performance!
As an mtber platinum or gold means nothing to me other than the colour of the borecaps on my Hope callipers – titanium on the other hand is what they make top end bike bits from so it is like gold to me. Get one and save yourself enough money for a new bike! Unless your fiance is a biker she won’t go for it on her finger though!
