Quick run down.
Gucci bracelet
Pros:
- you like it because you're a Gucci fan
- clasp is large and easy to open and close
Cons:
- I personally do not like the large clasp or the large rings that attach to the heart. It is a more industrial look but not very feminine IMO.
- Again, personal opinion, I don't like the font of the text on the heart. It looks a little cheap IMO, a little fake.
- Gucci is not a jewelry house. I cannot say how their jewelry will wear and tear in the long run and how much they will stand by their products.
Tiffany bracelet
Pros:
- you like it because you're a Tiffany fan
- Tiffany is a jewelry house. They will do free cleanings and long term repairs (usually free in the first year, and later a small fee down the line but they will still take it in.)
- The "Return to Tiffany" logo is a classic. It has a history and a meaning that has stood the test of time.
- It is a more feminine look if that's what you like.
Cons:
- The clasp is small and more dainty but it can be a pain to open and close. It may be a little difficult to put on the bracelet by yourself. It's something to get used to.
- The Tiffany chains are known to be very slim, dainty and minimalistic. It's a look, in it of itself, but it can also mean that it may be more fragile and prone to breakage if there is strong tugging or pulling involved. (I have a Tiffany DBTY necklace with also a very fine chain, never had a problem, but it's on my neck. It's much less likely to get caught on something compared to a bracelet.)
Cons of both: Neither are adjustable in length (but you may be able to request an extension with Tiffany). And the flat smooth surface of the heart will be prone to scratches and daily wear over time. Especially being on the wrist when we do so much with our hands. Just comes with the territory.
Hope that helps! Good luck and happy shopping!
