Crystal Weave

You choose a portion of Gemstone or Crystal that you can touch and that fits within a 5-foot cube. You manipulate it in one of the following ways:

• You can change the shape, color, or both. this will not change the actual type of gemstone, but can be passed off as a forgery of another type of gem. an investigation check made against your spell save DC will reveal that the gemstone has been altered.
• you can create engravings on or within the structure, spelling out words, creating images, or shaping patterns.
• Cleanly break the Gemstone down into a number of smaller peices without shattering it in the process.
• Combine multiple Gemstones into a cluster or geode.

For any of these uses, during any attempts to make complex alterations or designs, a skill check made be called for at the DM's discretion.
