Here is an extra large slider, decorated with acrylic gems. 

The crystals are held securely in a highly polished gold plated setting.

There is one extra large central stone, and sixteen smaller ones set around it.

Just click for a larger image.

They measure approx 20mm across.

These can be used for bracelets, maybe a watch band, sewing onto clothing and many other projects.

Sold individually, you need only buy as many as you need.
