These inclusions are typically needle-like or rod-like crystals. In black rutile, the rutile inclusions appear black, often due to the presence of other minerals like hematite, magnetite, or other titanium compounds within the rutile inclusions. Black Rutilated Quartz, also known as Tourmalinated Quartz, is a striking gemstone with a unique combination of properties believed to offer a range of benefits. It's essentially Clear Quartz with inclusions of black rutile (often composed of black tourmaline), creating beautiful needle-like patterns within the stone.”
