An inclusion not frequently found in quartz entails the existence of unique or odd materials that maybe lodged within a quartz crystal matrix as it crystallizes. Inclusions are most gorgeous and fascinating and their presence can boost the value and demand of the specific quartz specimen by a great deal. Some rare types of inclusions in quartz crystals include:
1. Rutile Inclusions: Needles of rutile (titanium oxide), so fine as to resemble hair, which can grow within the quartz, which may then give the crystal a golden or metallic, silvery appearance.
2. Tourmaline Inclusions: Needles or small grains of black or green tourmaline within the quartz; the effect is even more dramatic.
3. Lepidocrocite Inclusions: Red, orange or brown iron hydroxide crystals found as flakes or inclusions in the quartz giving it a fiery appearance.
4. Chlorite Inclusions: Tiny brownish, greenish resident inclusions which are mostly found in quartz and cause the crystal to look like it came from the forest.
5. Hematite Inclusions: Red or brown hematitic corrections of plate-like shape within quartz often imparting to the crystal a reddish tint.
6. Petroleum Inclusions: Oil globules of liquid hydrocarbons enclosed in quartz, occasionally containing small gas bubbles capable of movement inside the inclusion.
7. Cacoxenite Inclusions: Bronze or brownish needlelike inclusions in quartz that form a type of starlike figure.
8. Phantom Quartz: This appears when one set of quartz growths is included inside the other as a negative imprint of the formation of the crystal.
These inclusions make the Quartz distinctive and beautiful giving the metaphysical and esthetic desire for collectors and people interested in Crystals.
