Own design

After having scheduled an appointment, you can work together with Karla Mertens on the design of your piece of jewellery and have it made.





You may possibly have some jewellery lying around that you no longer wear !

We have an extensive jewellery collection available for you to choose from. For a transformation you need between 2 and 18 grams of gold and you will only be charged for the cost of making the item.   

Diamonds and/or precious stones originating from existing jewellery can be incorporated in a new piece of jewellery.

Feel free to visit our store and we will gladly provide you with no-commitment advice.

Old gold is also accepted as a method of payment.

Remembrance jewellery

Having to say goodbye to a loved one is a very difficult time in our lives.

In our store you can choose in all discretion and intimacy a piece of keepsake jewellery to treasure your most beautiful memories. 

Together with the customer a unique piece of jewellery can be designed and made. The ashes are kept in a cavity of the jewellery that can be filled and is secured by us.


Repairs on jewellery are an important part of our activities. Usually simple jewellery repair work can be collected after 10 working days.

Increasing and decreasing the ring size of your rings
We can enlarge your rings. When there are gemstones incorporated in the ring, this can make the enlargement process more difficult. We occasionally have to remove the stone as it is not heat resistant. After the ring is resized the stone is positioned back in its original place. We can also help you with decreasing the size of your ring.

Cleaning and rhodium plating of jewellery
We can make your jewellery look like new by giving them a thorough cleaning. Rhodium plating is the last process for white gold and silver jewellery in order to provide them with extra white shine and a protective barrier against oxidation.

If you have lost a gemstone from a ring or from another piece of jewellery, you have come to the right address to have the stone replaced or set again in your jewellery.

Our workshop is equipped with engraving devices. If you prefer to have your own typeface or symbol engraved, we can personalise your jewellery manually.

Knotting and stringing
Our services also include the knotting or stringing of pearls, beads and gemstones into a necklace. A new contemporary clasp or connector can upgrade the necklace.

Ear piercing
Ear piercing is a gentle, silent and hygienic operation. (we use a painrelieving agent)

Piercing the ears of children can only take place when they are 5 years old and over.

We make use of the Studex system. In order to make the process perfectly hygienic, we each time use a new and sterile disposable device.

View our method of working for ear piercing.

For our young customers that are coming to us for their very first earrings and that have their ears pierced: a genuine silver ring with a coloured stone for FREE  ( - as long as our stock runs. - )

At the request of our customers we appraise the value of jewellery. These appraisals can be essential for the partition of an estate, theft insurance or inheritances.

Advice on your personal stones
We are happy to advise you when choosing the right gemstone that matches your personality. By appointment please.
