Many Swarovski crystals require cavities in order to be applied to
materials. A properly produced cavity in combination with a suitable
gluing system ensures a stylish, long-lasting application. The cavity
makes it easy to glue properly and ensures a higher protection of the crystal against mechanical and chemical stress.
There are several different production methods and cavity types. Always take into consideration the requirements and base material of the finished product when choosing the appropriate cavity, pre-treatment method and kind of glue.
- Drilling is when materials are machined using a power drill and drilling tool.
- Milling is when materials are machined using a milling machine and milling cutter. Milling machines can be fitted with appropriate tools depending on the materials, e.g. for working with metal and plastic, wood or natural stone. Modern CNC machining centers offer the greatest precision and can be used to produce cavities of every shape necessary. Please note that when machining natural stone, ceramic or glass, for example, special diamond-tipped tools must be used.
- Water jet cutting allows materials to be separated via a high-pressure jet of water. Economic reasons make water jet cutting machines ideal for certain crystal shapes that are integrated into flat materials. Please note that only end-to-end cavities can be produced in this way. In addition, materials which swell through water cannot be worked with. Absorbent materials must be fully dried before gluing the crystal.
- Casting: To reproduce cavities, particularly in the jewelry sector, the cavities can be made when the metal component is cast. When following this process, the cavities must be cut into the original model. To prevent the bottom of the cavity being rounded off, which would result in the crystal sitting too high, it is recommended that an additional indentation is made when producing the original model.
Further instructions on jewelry production can be found in the “Soldering, plating and stone setting” chapter.
Depending on the Swarovski crystal used, various cavity types can be made using the different production methods.

Production tolerances for cavities
When producing cavities, the dimensions should be based on the main dimensions, including the maximum tolerance for the crystal components used, and the production tolerance. These dimensions can be requested from your Swarovski sales organization.
