Imperial Topaz Brazil Natural Golden Orange Crystal Mineral Specimen 10-25mm Genuine Collector Stone with Certificate
£ 8.16
IMPERIAL TOPAZ – NATURAL BRAZILIAN CRYSTAL SPECIMENThis genuine Imperial Topaz from Brazil is a naturally coloured variety of Topaz
prized for its warm golden to orange tones and well-formed crystal habit. Carefully selected for colour, structure, and collector appeal, each specimen measures approximately 10–25mm. The photograph shows an example of the actual specimen you will receive. Please refer to the listing images for full sizing and natural variation within this range.Your Imperial Topaz includes a Certificate of Authenticity lifetime guarantee generic card, confirming it is a 100% genuine natural mineral specimen. MINERAL SPECIES & CHEMICAL COMPOSITIONImperial Topaz is a colour variety of the mineral Topaz, an aluminium fluorosilicate with the chemical formula:Al₂SiO₄(F,OH)₂It belongs to the nesosilicate mineral group and crystallises in the orthorhombic crystal system. The distinctive golden, honey, peach, or orange tones are typically caused by trace elements and colour centres formed during geological processes.Key mineralogical properties include:
• Mineral Group: Nesosilicate
• Crystal System: Orthorhombic
• Hardness: 8 on the Mohs scale
• Lustre: Vitreous
• Transparency: Transparent to translucent
• Cleavage: Perfect basal cleavageTopaz is one of the harder naturally occurring silicate minerals, contributing to its durability and popularity among collectors and gem enthusiasts. COLOUR CHARACTERISTICS & CRYSTAL HABITImperial Topaz is especially valued for its rich and saturated colour range, typically including:
• Golden yellow
• Honey tones
• Peach
• Orange
• Pinkish-orange huesBrazil, particularly the Minas Gerais region, is historically renowned for producing high-quality Imperial Topaz crystals. Even within the 10–25mm size range, crystals may display well-defined prismatic forms with flat terminations and vertical striations along the crystal faces.Natural inclusions, minor internal fractures, and subtle zoning may be present and are characteristic of authentic geological formation. No artificial dyes are used. GEOLOGICAL FORMATION – BRAZILIAN DEPOSITSImperial Topaz from Brazil commonly forms in hydrothermal veins and in altered granitic environments, particularly in areas influenced by late-stage magmatic fluids. These fluorine-rich fluids are essential for Topaz crystallisation.The crystals grow within cavities and fractures in host rock, often associated with quartz, mica, feldspar, and cassiterite. The unique geological conditions in Brazil contribute to the distinctive colour saturation associated with Imperial Topaz from this locality. COLLECTING & DISPLAY APPEALImperial Topaz is highly regarded by mineral collectors for both its geological significance and its visual appeal. The 10–25mm size makes these specimens ideal for:
• Mineral display cabinets
• Micromount or small crystal collections
• Gemology study
• Collector gift pieces
• Educational geology setsIn some traditions, Imperial Topaz is spiritually associated with abundance and confidence; such associations are belief-based rather than scientific. AUTHENTICITY & INDIVIDUAL SELECTIONEach Imperial Topaz specimen is carefully chosen for natural colour and crystal character. The listing photograph shows an example of the actual specimen you will receive within the stated 10–25mm size range. Please review all images for scale and natural variation.Every piece is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming its genuine natural origin from Brazil.A classic example of orthorhombic crystal growth in fluorine-rich geological environments, this Brazilian Imperial Topaz specimen offers striking colour, mineralogical importance, and strong collector appeal in a versatile display size.
