A discarded cuttlefish bone is used to make a simple wedding ring using hallmarked sentimental gold. This gold can be 9ct, 18ct or 22ct and it can be sentimental because it  belonged to grandparents, parents or  other loved ones. It is a very simple but meaningful way to re-design and re-use old wedding rings.

The cuttle fish is prepared by cutting it in half and rubbing the two halves together, to create two flat surfaces.

An impression of a wedding ring is formed by pressing the two halves of the soft cuttlefish bone together with a silver wedding ring inbetween them.  Guide beads and a sprue are used to create access for  the molten gold to be poured into the cuttlefish.

The silver wedding ring is the exact size and type needed to replicate the re-designed wedding ring using the sentimental gold. This could be d-shape or flat, plain or hammered finish. 

The cuttlefish is pressed together so that the impression of the siver wedding ring is left on both sides.  The sprue is removed and the access for the gold is improved to allow for ease when pouring the gold.

The guide beads are left in and breathing lines are added using a scalpel to allow air to escape.

The cuttlefish is bound together and clamped in a vice. The hallmarked sentimental gold is heated up in a crucible using a torch. When the gold is molten the crucible is poured into the access hole of the cuttlefish. 

This gold will run into the impression left by the silver wedding ring witnin the cuttlefish. Resulting in a re-cycled gold wedding ring.

When the cuttlefish has cooled down, the binding is removed to reveal the cast wedding ring with the sprue still attached. A new lease of  life has been created using loved ones' gold, which will have all the sentimentality combined in a re-designed wedding ring.

The wedding ring is detached from the sprue, filed and polished or left with a brushed effect or hammered finished, depending on the desired finish agreed upon to start with.

The cuttlefish can be kept by the customer if they would like it, as it shows how a new lease of life was created using loved ones' gold.
