Yes, it is gone. Talk to the dealer who sold you the cartridge, as they might be able to either retip the cartridge or even offer you a trade-in on a different cartridge. (This happened to my Benz Micro Glider II, due to its exposed cantilever.)
Look upon it as a learning experience. (I did, and will no longer buy cartridges with exposed cantilevers. I bought a Koetsu, which has a fairly well protected stylus and a stylus guard!)
Good Luck.
