Specimens of milky quartz with small amounts of rutile crystals from Ben Lawers, Perthshire, Scotland, UK. Rutiles are a titanium mineral, dense and black, it is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks but found in very few locations around the world. These specimens feature small amounts of brown-red to black rutile crystals and some samples also have chlorite present. Specimens are supplied in white card trays with information labels or small perspex magnifier boxes. These samples would make an ideal addition to any British mineral collection.
