Custom Jewellery Design

When you begin the wonderful exciting journey of working together with Ernst on your new creation let us know what you like (send images, drawings, dimensions & your ideas).  We will discuss it thoroughly with you to be sure of your requirements before the design process begins of your customised piece.  When you are completely happy with the design, Ernst will personally handcraft it for you.

When looking through our online gallery, if there is a design that you like but would prefer different gemstones/diamonds of the same size, this can be accommodated subject to availability.
