Jewellery clinic’s, jewellers take the time to carefully examine your jewel in order to determine the work that needs to be done.
This delicate step requires very specialised know-how in order to assure that the original shape of the jewel is not altered. Only experienced polishers are able to perform this service. Polishers use brushes saturated with abrasive pastes. Three different pastes are used one after the other in order to obtain a reflective result. Sanding involves the use of a very hard brush and a very abrasive paste to eliminate scratches. Polishing involves the use of a hard brush and a hard paste to refine the condition of the original surface. Shining involves the use of a soft brush and a fine paste to buff the model and give it its final shine.
After the shining operation, on your jewel is submerged in a bath filled with lukewarm soapy water and ultrasound waves. Ultrasound waves clean the less accessible parts of your jewel (not including emeralds, pearls and certain stones that are too delicate for ultrasonic cleaning).
4. Rhodium plating
(If your jewel is rhodium plated) White gold is sometimes covered with a fine layer of rhodium to enhance the whiteness and brilliance of your jewel. Rhodium is rare, precious and resilient white metal in the platinum family; it is therefore necessary to follow these additional steps.
Before polishing, eliminate rhodium which consists in removing the layer of rhodium to obtain a neutral base for the new treatment.
After polishing, perform a rhodium bath so that a very thin layer of rhodium is deposited on the white gold surface after polishing. This layer brings out the whiteness and brilliance of the surface.
5. Technical and aesthetic control
The jeweller performs a final technical and aesthetic control in order to assure that your jewel meets GR Jewellery Clinic’s quality standards
