Just wanted to chime in here and say that I wore my platinum tennis bracelet daily for almost 5 months and by almost 5 months of daily use the clasp was starting to get loose and would easily come off if it got caught on something. First of all I was advised against using platinum for a tennis bracelet/necklace since the metal is too soft for a tennis setting and all the jewelers said it would stretch over time since they are linked together, but I was planning to wear it 24/7 and didn’t want to deal with rhodium plating or seeing plating wear off since I’m very allergic to nickel so insisted on a custom order in platinum.
Luckily when it fell off it always happened at home while I was changing my clothes but it did freak me out, so I had it tightened again and found the best way to wear them was to sandwich the bracelet between two Loves so the clasps never really stick out if that makes sense. The Loves act like a guard on both sides. It does cause more scratches on the Loves though, so I have since stopped wearing it 24/7 because I wasn’t expecting platinum to stretch and loosen so soon (less than 5 months of daily wear). People might have better luck with 14K white gold which is recommended since it’s more stiff as a metal, lighter, and “harder” therefore less prone to stretching and loosening.
I didn’t want to add a safety chain because I personally don’t like the look of it, but it’s definitely a good idea if you can tolerate the extra look of the chain.
