FAQs for jewellery cleaning, repairs and valuations

To maintain your jewellery's brilliance, schedule professional cleaning with a jeweller every 6-24 months, considering wear frequency and material type. Annual cleaning is recommended for heavily worn pieces, while occasional wear pieces can be cleaned every 2-3 years. Prompt cleaning is advised if visible dirt, dullness, or discoloration appears.

Certain materials (e.g., pearls, opals, emeralds) require specialised care when cleaning. It's wise to come in and have a chat to us and we can give you professional cleaning advice as to what at-home jewellery cleaning you can do and what you should bring to us.

Ultrasonic cleaning is a professional jewellery cleaning method that utilizes high-frequency sound waves to create a gentle yet effective cleaning solution. This non-invasive process uses a specialized machine to emit vibrations that dislodge dirt, grime, and oils from intricate jewellery designs, crevices, and settings, restoring brilliance and shine. 

Most jewellery can be repaired and we can source precious metal and gemstones for this work. However if a piece is beyond repair, we can discuss with you the options to transform the sentimental and valuable elements of the original item into a stunning new piece. 

An appraisal describes a piece of jewellery's characteristics, while a valuation determines its monetary worth.
