Hi Klos,
I am a Catholic and I do go to Mass. I have several crosses, some plain crosses, others crucifixes. You get a lot when you are baptised, 1st holy communion etc. I rarely wear a cross though, which may sound odd. Not because I feel self conscious but I don't wear the ones which were given as presents, I would hate to lose those. Also, I don't feel like I have to make a religious statement. However, I bought an 18ct WG cross with a red labradorite and diamonds from Rocks.tv about 6 months ago and I do wear that one for purely because it is so lovely. I never wear one at work as I would hate to make anybody feel awkward. I work in ITU and patients and their families are extremely vulnerable emotionally at times like these. I respect all believers & atheists alike.
However, a cross isn't a crucifix! Crosses have been seen as fashion and religious symbols for thousands of years and can been readily found in Muslim items such as Kilim rugs. I spent a few years in the Middle East and brought back a few great old rugs with crosses in the pattern.
I say if you like it and will wear it, buy it, just the same as with any other jewellery.
Hope that helps Klos,
Inge xxx
