Mystery Mineral in Tabletop Fountain

[DaveC426913]

This crystal was left over after the water in a tabletop foundation evaporated. The fountain is a collection of rocks glued together that the water tumbles over.

The crystals are off-white, slightly straw-colured. The image is about 2X actual size.

Any idea what the mineral may be?

Looks like there may be enough there to do a rough qualitative analysis...if you have access to reagents. Or, would you happen to have an x-ray diffractometer handy ?

It is difficult to accurately identify the mineral without a closer examination and some additional information. However, based on the description of the color and size, it is possible that the crystal could be calcite or quartz. Both of these minerals can be found in a variety of colors and are often used in tabletop fountains. It is also possible that the crystal could be a type of feldspar, which is commonly found in rocks and can have a straw-colored tint. Without further details or a photo, it is difficult to determine the exact mineral, but these are a few possibilities to consider.
