Had my engagement ring approx 18 months and it's broken twice - once stone was wobbly and now one of the claws holding stone in has snapped off (just the tip of it has snapped off).
Ring is 18 carat white gold with a (fairly) large coloured stone (not diamond).
I got it from Hatton Garden. Both times shop has fixed it for free (as I would expect!) but I'm really upset this has happened at all - is this normal?
I'm half tempted to ask for a refund although I would be very upset as I love the ring and it obviously has great sentimental value so don't really want to replace it, but I can't have it breaking every few months.
I'm worried we've been ripped off and sold a shoddy ring and am thinking of getting it valued at an independent jewellers - but I will be gutted if they say it's worth a lot less than DH paid for it 
I thought Hatton Garden would be good quality, but maybe not?
Any advice appreciated
