Mix sizes (approximately 0-6cm) Quartz crystals 

1. Color: Quartz occurs in a wide range of colors, including clear (colorless), white, purple (amethyst), yellow (citrine), pink (rose quartz), brown (smoky quartz), and more. The color variation is due to impurities within the crystal structure.

2. Hardness: Quartz has a hardness of 7 on the Mohs scale, making it relatively durable and suitable for various applications, including jewelry making and industrial uses.

3. Clarity: Quartz can range from transparent to translucent to opaque, depending on the presence of impurities and structural imperfections. Clear quartz is prized for its transparency and often used in jewelry.

4. Luster: Quartz typically has a vitreous luster, meaning it appears shiny like glass when polished. However, some varieties may exhibit different lusters, such as the dull luster of smoky quartz.

5. Density: The density of quartz varies depending on its composition and structure, but it generally ranges from 2.65 to 2.66 g/cm³.

6. Metaphysical Properties: Quartz is believed to amplify energy and intentions, making it useful for enhancing the properties of other stones or objects. It is thought to have protective properties, shielding the wearer or space from negative influences and electromagnetic radiation.
