Diamonds are a girls’ best friend. And if it is a friendly gizmo, the key USB Swarovski Crystal Engagement Ring is the best way to woo her.

J Flume Design has developed a USB Flash drive Swarovski Crystal engagement ring. Even if a diamond is attached to the ring, a USB key is hidden in the bush.

The developer explains that these rings users will be able to transfer data between two rings, once they are joined. Plus users can transfer data from the device to the computer and vice-versa, with the help of collar provided.

This necklace features a standard USB port, a mini-USB port, as well as two “sharing ports for transfer between two rings.”

However, the rings are still at the conceptual stage. And no launch date or other details have not been disclosed at this time.
