A Grade Spinel Crystal Burma Natural Octahedral Mineral Specimen 9-12mm Genuine Collector Gem Display Stone with Certificate
£ 8.40
A-GRADE SPINEL CRYSTAL – NATURAL MINERAL SPECIMEN FROM BURMAThis A-grade Spinel crystal from Burma is a genuine natural mineral specimen,
carefully selected for colour, crystal form, and overall display quality. Each piece measures approximately 9–12mm, making it an ideal size for mineral collectors, gemstone enthusiasts, or curated display collections. 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 size range.Your Spinel specimen includes a Certificate of Authenticity lifetime guarantee generic card, confirming it is a 100% genuine natural mineral from Burma (Myanmar). MINERAL SPECIES & CHEMICAL COMPOSITIONSpinel is a magnesium aluminium oxide mineral with the chemical formula MgAl₂O₄. It belongs to the oxide mineral group and crystallises in the isometric (cubic) crystal system. One of Spinel’s most distinctive features is its natural tendency to form sharp, well-defined octahedral crystals, which are highly sought after by collectors.Spinel ranks 8 on the Mohs hardness scale, making it a durable mineral species valued both in mineral collections and in gem-quality form. Unlike some gemstones, natural Spinel is typically singly refractive due to its cubic crystal structure. GEOLOGICAL FORMATION – BURMESE SPINELBurma (Myanmar) is historically one of the world’s most important sources of fine Spinel. Burmese Spinel commonly forms in metamorphic marble deposits, where high temperatures and pressures allow magnesium- and aluminium-rich rocks to recrystallise and form Spinel crystals.These crystals are often found embedded within calcite marble matrix or weathered free from host rock. The geological conditions in Burma have produced some of the most intensely coloured and well-formed Spinel specimens known.Associated minerals in Burmese deposits can include calcite, dolomite, phlogopite, and corundum. The formation environment contributes to the clarity, colour saturation, and crystal sharpness that collectors prize. COLOUR, CLARITY & CRYSTAL CHARACTERISTICSA-grade Spinel from Burma is particularly appreciated for its strong colour and crystal definition. Natural colours may include red, pink, deep rose, or reddish-purple tones depending on trace element content, particularly chromium.Key mineralogical properties include:
• Mineral Group: Oxide
• Chemical Formula: MgAl₂O₄
• Crystal System: Isometric (Cubic)
• Typical Crystal Habit: Octahedral
• Hardness: 8 Mohs
• Lustre: Vitreous
• Transparency: Transparent to translucentNatural inclusions, minor surface features, or growth zoning are normal in authentic Spinel crystals and reflect their natural geological origin. No artificial colour treatments or enhancements have been applied to this specimen. COLLECTING & DISPLAY APPEALSpinel has long been valued in both mineral and gemstone collections. Historically, some famous “ruby” gemstones in royal collections were later identified as Spinel due to their similar colour but distinct mineral composition.The 9–12mm size range makes this specimen suitable for mineral trays, gem display cases, or educational collections focused on crystal systems and oxide minerals. Its sharp crystal geometry and vibrant colour make it particularly appealing for collectors of well-formed natural crystals.Spinel is traditionally associated in some cultural belief systems with vitality and inspiration; these associations are spiritual rather than scientific. AUTHENTICITY & INDIVIDUAL SELECTIONEach Spinel crystal is a carefully chosen A-grade specimen from Burma. The listing photograph shows an example of the actual specimen you will receive within the stated 9–12mm size range. Please review all images for scale and natural crystal variation.Every piece is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming its genuine natural origin.A classic example of Burmese octahedral Spinel, this A-grade mineral specimen offers striking crystal form, geological significance, and collector value, making it a refined addition to any serious mineral or gemstone collection.
