Behold...the first piece of Sonic the Hedgehog jewelry! This is a real silver ring. It was released for the 10th Anniversary. It WAS available in the USA, but only through website ordering. It was one of a trio of items for the 10th, all very expensive. (Crystal Cube and Marble Base Statue are the other 2) The adjustable ability of the ring cheapens the feel a bit, but it looks to be well constructed none-the-less. As you can see, it came with all kinds of fancy boxes and documentation. It is believed to have sold for around 50 bucks. Now, it is probably far higher. Not many were made or sold in the US due to the high cost. Truly a gem in any collection!
Here's a real detailed look at the 10th Anniversary Sonic face sterling silver ring. You can see how the detail lines like the eyes & ears have collected the black tarnish from age. This also lets you see into the band, where it is stamped with the Sega copyright & 925 Sterling marks. The band not closing in the back is a part of the design (as well as making it slightly adjustable) since it is formed by 2 of the spikes. It's quite a 3D and decorative ring.
You wouldn't want to wear it because of the nose that sticks out so far. This remains quite high end & sought after. The one appearing here is either around 800 or 900 or so on Ebay. It's interesting to get a really good look at it here, as it is an unlikely thing to own.
