### Birthstone Research Guide

To provide detailed and educational information about your birthstone, please follow the steps outlined below. Note: Your month may have multiple 'stones'. For example, the birthstone for June is sometimes listed as a pearl, but that is not a mineral; keep digging (pun intended) for the birthstone mineral.

1. **Give the name and chemical formula for your birthstone.**
   - Example: Citrine (a variety of quartz) is SiO₂.

2. **What class of minerals does your birthstone belong to?**

3. **Provide some information about the mineral's properties.**
   - Include color, hardness, luster, streak, cleavage, and any special properties.

4. **What element(s) impart color to this mineral?**

5. **Identify some industry or commercial uses of the mineral (besides jewelry).**

6. **Provide a "fun fact" about your birthstone.**

7. **Name at least two geographic places where this mineral is found/mined.**

8. **Find a photo to illustrate your birthstone and insert it into your post.**

By following these steps, you will be able to comprehensively research and present detailed information about your birthstone.

**GENERAL**

Did you know that 98% of the Earth’s crust is made up of only 8 elements? This means that the most minerals, including many birthstones, are made of these 8 elements. Minerals can be identified by their physical and chemical properties, which is a function of the elements from which they are formed. Like a fingerprint, each mineral type has its own special characteristics and chemical composition. This discussion will be an opportunity to get personal with a few elements, and a few special minerals.

**DIRECTIONS**

**Part A - Creating a “Crusty Mnemonic” for the 8 most common elements in the crust**

1. List the eight most common elements in the crust in descending order with the percentage in parenthesis next to each element. Example: Oxygen (47%), Silicon (28%)...

2. Compose an original mnemonic based on the eight most common elements in the crust. The elements should be listed in decreasing order of abundance (from highest to lowest), so start with an "O" word to represent Oxygen, then an "S" word to represent Silicon, and so on. Creativity and humor is encouraged. The idea is to make something catchy or funny that would help you remember these elements in order. Here is one of my favorites from last semester:
