Stock Jewellery Items

All our stock items have been designed and made in our workshop by Ernst Pfenninger, Swiss/Australian designer goldsmith and silversmith at our Studio 303, Sydney, Australia, and are available for you to purchase.

Custom Jewellery Items

At Studio 303, Ernst Pfenninger designs and makes each piece. For custom made work we work closely with our customers to ensure each design meets their expectations. When you have approved your design, full payment is required before commencing your piece/s. If all components are available, our usual timeframe for completion is 2 to 4 weeks, depending on the item ordered. If special materials need to be sourced we will discuss this with you as part of the design process.

For earrings, please advise if they are for pierced ears and what kind of findings you prefer depending on the design you have chosen. For example shepherds hooks, posts & butterflies (small, medium, large) or posts & special screw findings, locknuts, or for non-pierced ears what type of clip if available and suitable for the piece.  

Pendants and brooches, may be designed to incorporate both functions of a pendant and brooch in one item. This can make the item multi-functional, however this is subject to the design selected.  We have several brooch/pendant combinations in our shop.

For corporate and/or for individual orders, jewellery or other items these can be ordered in small to larger quantities, depending on the design and materials required.   

Customised items cannot be returned because they have been made especially for you, nor is a refund available. Therefore please ensure that prior to proceeding with your order you have thoroughly checked all the details and that you are satisfied that the item/s meets all the design brief. Once a design has been approved by you to start production it cannot be altered after production has commenced. If however a minor change can be made we will discuss this with you and it may incur a further cost. 

Ring Sizing (also refer to the ring sizing information sheet)

It is important that your ring size measurement is correct.  We recommend this to be checked by a reputable jeweller using a jewellers’ metal sizer.  Please do not use string, paper or thin plastic sizers as these are not accurate.

It is important to note there can be a different ring size required for narrower or wider ring bands. If possible, it is recommended to use a ring sizer similar to the finished size of your ring.  For example, wider rings may require a slight increase in size compared to a slimmer ring (approximately half to one size depending on the finger shape). Please advise the ring sizer width you used so we can make the appropriate adjustments as described above. Kindly contact us if you require further clarification or advice.

A Vernier calliper will give you an accurate ID (internal diameter) measurement.

There are many ring sizer charts on the internet with conversions for different countries. We have supplied a ‘ring size comparison chart’.

A firm plastic ring sizer with a clip to lock in the size is also available on the internet for just a few dollars and if using it please advise the width of the sizer you are used.

Finger sizes can change during the day, depending on the weather, fluid retention, air conditioning, breast feeding, medical conditions, exercise and other factors. Please check your finger size a few different times of the day to ensure the size you are sending to us is correct.

Ring Re-sizing Prior to Sending Your Order

There is one complimentary resizing at the time of your order.

If you can come into our shop (Studio 303) we can check your size and make the appropriate adjustment. Kindly check our shop opening hours.

If extra gold is required to enlarge a ring we will advise you of any extra costs involved, if applicable.

Ring Resizing After You Have Received Your Order
