We want to take the time to share a story with everyone, a story of how we successfully managed to reproduce a ring for one of our customers, Claire, as we shall name her for the purpose of this article.

Claire fell in love with her sister’s diamond ring and wanted to get the exact same one for herself but made from a 18K yellow gold instead of 18K white gold. She asked the original jeweller if it was possible for them to sell her the same ring in yellow gold. Unfortunately, it was not possible because they did not have such a ring in stock or their own workshop where they could reproduce it.

After visiting a few jewellers in town, Claire came across our jewellery workshop where we told her we could make an exact replica in any metal she liked. Overjoyed, she agreed to bring in her sister’s ring (as seen below) where we could start the process. So exactly how did we reproduce the ring?

Step One: Making of the Wax Model

There are several ways in which a ring can be reproduced that include it being created in CAD (3D computer modelling software) or cast from a wax model. While CAD software is excellent at designing almost anything, we encouraged her to go for the wax model because it will allow her to hold and get a feel of the ring before we cast it from gold. It will also give her the opportunity to make changes and see them in real life before her ring is casted.

We made a mould from her sister’s ring where we then poured in hot wax to create the wax model, as seen in the image below.

*P.S. our camera was not working at the time, so these pictures have been taken from an old mobile phone.

You can see that there are two parts to the. On the left is the setting that firmly holds the diamond in place, and on the right is the main band/shank.

Step Two: Casting from Gold

To cast the ring, we take hot smelted gold and pour it into a mould. After the gold has cooled and hardened, we break open the mould and reveal a rough copy of the ring. As you can see, the gold ring is does not look anywhere as near as pretty as a completed ring because we still need to add the finishing touches that include it being polished to perfection.

Step Three: Setting the Diamond and Polishing

Tommy, our master goldsmith who has more than 50 years of experience working with gold, completes the ring by soldering on the setting and giving it an extreme polishing that brings out the shine of gold we are all too familiar with.

The yellow gold ring is an exact duplicate of the white gold one, so much so that the diamond from the white gold ring fitted perfectly into the yellow gold one – without needing any modifications. Martin, our professional diamond setter, replaced her sister’s diamond back into its original place and set a new one into Claire’s ring before giving it a final polish and clean.

The Result was one very happy Claire. She was overjoyed and could not stop thanking us enough that she now had a ring she had only dreamed of having only a few weeks back.
