Mineral Species & Composition Citrine is a yellow to golden-orange variety of quartz, composed of Silicon Dioxide (SiO₂). It belongs to the macrocrystalline quartz family, valued for its attractive colour range and durability. Key mineral information: Mineral Species: Quartz (Citrine variety) Chemical Formula: SiO₂ Crystal System: Trigonal Hardness: 7 on the Mohs scale Lustre: Vitreous (glass-like) Transparency: Transparent to translucent Colour: Pale yellow to deep golden tones The natural colour of citrine is typically caused by trace iron impurities within the quartz crystal structure, influenced by geological heat conditions during formation. Geological Formation & Congo Origin Quartz crystals form in a wide range of geological environments, including hydrothermal veins, pegmatites, and metamorphic rocks. Citrine develops when quartz crystallises under conditions that allow iron-related colour centres to form naturally. Congo is known for producing attractive quartz varieties, including naturally coloured citrine, with warm tones and good clarity. These crystals often occur in mineral-rich geological terrains shaped by hydrothermal activity. Associated minerals in quartz-bearing environments may include: Amethyst Smoky quartz Feldspar Tourmaline Mica minerals The geological processes responsible for citrine formation occur over millions of years, resulting in durable, collectible quartz specimens. Polished Finish & Visual Appeal This specimen has been polished to enhance its natural colour and reveal internal features. Polishing brings out: Golden-yellow colour depth Glassy reflective lustre Internal clarity and natural inclusions Smooth tactile surface for display The polishing process does not alter the mineral itself; it simply refines the surface to showcase the crystal’s natural beauty. Natural internal veils, inclusions, or growth patterns may be visible, adding individuality to each piece. Size & Display Uses (15–35mm) With a size range of approximately 15–35mm, this polished citrine specimen is ideal for: Mineral and quartz collections Display shelves or specimen trays Educational geology sets Jewellery or lapidary projects (subject to suitability) Unique gifts for crystal enthusiasts Its compact size makes it easy to store or present while still offering strong colour and collector appeal. Collecting & Traditional Associations (Non-Medical) Citrine has long been admired as one of the most recognisable quartz varieties, valued for its warm colour and rarity in natural form.
