Multiple elongated prisms may connect together, forming clusters that are beautiful and spectacular, exhibiting a wide variety of shapes. 2. Specific Gravity: 2.56–2.66 grams per cubic centimeter. This indicates the weight of a given volume of crystal compared to the same volume of water, which is 2.56–2.66 times heavier. The density of massive varieties of quartz may be slightly higher. 3. Streak Color: Colorless. The color of a mineral’s powder is called the streak. It can eliminate false color, weaken secondary color, and retain intrinsic color,…
