116 - 14 Sided Gem Impression Die

This steel jewellery impression die produces a 14-sided gem design in silver, gold, copper and pewter. These gems add a reflective, eye catching accent to your work and can also form the main focus of earrings, a pendant, ring or brooch. Although it's possible to create this design with a hammer and punch, due to the polished 'slippery' die surfaces the best results will be achieved with a hydraulic press.

There are 3 other impression dies in this gem set.

  • Instructions

    Can I use this tool with a hammer and a punch?

    Yes - Please note - this design is fairly deep and the best results will be achieved using a hydraulic press. It's still possible to get good impressions with a hammer and punch if your technique is sound and your setup is solid and rigid. Anneal your metal regularly.

    When using a hammer and punch, it's crucial to work over a solid and rigid surface such as a stump, anvil or a concrete floor. Without a solid surface, no amount of hammering will produce good results! The size of your hammer plays a big part too - a 4lb lump hammer is ideal. Always use a punch when hammering your metal. Be careful to avoid striking the hammer directly on the die or shot plate.

    Can I use this tool with a hydraulic press?

    Yes, all Gemina impression dies and shot plates can be used in a press. Ensure your metal is annealed regularly before you begin. Intermediate annealing may be required to achieve a full impression.

    How much silver do I use with this design?

    You can use approximately 2g of silver to achieve a solid impression.

    What shape of silver can I use?

    Round shot:

    Melt your metal into round shot and flattened enough to cover most of the design. For best results, clean or pickle your metal before placing into the die. Use a hammer and punch (or press) to force the silver into the die. If hammering, anneal your metal after every 3 or 4 heavy blows.

    The gem dies have polished surfaces meaning you can minimise further polishing after striking your gems (and losing the sharp gem edges) by using Scotchbrite and a polishing cloth on your shot before hammering or pressing. You can also wipe the dies before striking with a polishing cloth for extra shine. It helps to squash your shot slightly before placing into the die to reduce the amount of forming required.

    Removing your impression from the die

    Occasionally, some dies can 'hold on' to your metal. This is more common when using a press compared to hammering. Ensure the dies are clean before use. If you wish, you can apply a very small amount of oil into the die before forming as this can help removal. Excess metal will create a flange around the design that will aid in removal after hammering or pressing. Carefully use a thin bladed knife under the excess metal to lift the impression out of the die.
