Now here's a jewel hot enough to make grown men weep. Literally. This little piece of finger bling doubles as a weapon. Filled with pepper spray (which is 400 times stronger than the average jalapeno), this neat accessory could become your new best friend, particularly if you have to ride the subway alone in the wee hours.

The ring is available in gold or silver and in sizes 6 to 14; each refill costs $8.

Implications - Personal protection gadgets aren't new, but sleek self-defense tools that double as attractive accessories are. Wearable pepper spray keeps a weapon easily accessible at all times, which saves precious time in the case of an emergency.
