Flashing "Diamond" Ring, retail $2.99 http://www.partycity.com...)

The Flashing "Diamond" Ring is a ring with a rather large and gaudy plastic "diamond" that hosts a dirty little secret: A blue LED inside the "gem" flashes when you twist the "gem".

It was intended to be used at a party; at such events you can easily get away with things that are exaggerated or out of proportion.

The ring portion (the part that fits your finger); although made of hard plastic, has an open bottom so it should accomodate a somewhat narrow range of finger sizes (it fits comfortably on my pinkie finger, but it's too tight to fit my ring finger).

It appears to be disposable (actually, it indicates so right on the back of the packaging materials).


Place the ring on your finger much like you'd put any other ring on.

Turn the "diamond" clockwise (as though tightening it) to activate it.

Turn the jewel counterclockwise {anticlockwise} (as though loosening it) to neutralise (turn off) the ring.

This ring is disposable, so I don't have to tell you which part to remove, carry to an open-pit copper or gadolinium mine, instruct you to huck it in there so that a front-end loader runs over it & causes it to 'destruct', and then rather emphatically tell you not to.

This was intended to be a disposable product, so even if you do manage to break it, just throw it away and go get another one. At $2.99 apiece, it really isn't that expensive.

Because this is a disposable ring and not a flashlight meant to be thrashed and abused, I won't try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, huck it into an open grave, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight.

Test unit was purchased at the Party City store in Federal Way WA. USA on 10-17-12.

Reasonably light weight despite being battery-operated
The price isn't too bad

Fits one of my fingers only; not the other three (not incl. thumb)

Marketed as being disposable -- that means a nice LED whirls down the {vulgar slang term for caca}bowl when the batteries go to pot
