Peruvian Pink Opal Tumblestone 10-20mm Polished Rose Opal Stone Natural Gemstone Specimen Gift with Certificate Authenticity
£ 1.56
Product OverviewThis Peruvian Pink Opal tumblestone is a genuine natural gemstone, carefully
selected and polished to highlight its soft rose-pink tones and smooth finish. Each piece measures approximately 10–20mm and is supplied with a Certificate of Authenticity lifetime guarantee card. The listing photograph shows a representative example of the quality and appearance you will receive, ensuring consistency while still reflecting the natural variation found in genuine mineral specimens.Mineral Identification and CompositionPink Opal is a variety of common opal, classified as a hydrated amorphous silica (SiO₂·nH₂O). Unlike precious opal, it does not typically display play-of-colour, but instead is valued for its uniform pastel hues and delicate appearance. The colour is generally attributed to trace elements and microscopic inclusions within the silica structure.This material is often referred to as “Andean Opal” when sourced from Peru, one of the world’s most notable localities for high-quality pink opal deposits. Its consistent colouring and fine texture make it particularly desirable for tumblestones and polished pieces.Crystal Structure and Physical PropertiesAs an amorphous mineral, opal does not form a traditional crystal lattice, distinguishing it from crystalline gemstones. Instead, it is composed of microscopic silica spheres arranged in a non-crystalline structure.Typical characteristics include:
• Colour: Soft pink to rose, sometimes with subtle cream or peach tones
• Lustre: Waxy to vitreous when polished
• Transparency: Opaque to slightly translucent
• Hardness: Approximately 5.5–6 on the Mohs scaleThe tumbling and polishing process enhances the natural surface, producing a smooth, tactile finish that highlights the stone’s gentle colouration.Geological Origin and FormationThis specimen originates from Peru, where pink opal forms in volcanic environments. Silica-rich solutions percolate through host rock, gradually depositing opaline material in veins and cavities. Over time, the accumulation of hydrated silica creates dense masses of opal with consistent colouring.Peruvian deposits are especially valued for their stable, opaque pink opal, often found in association with volcanic host rocks. The geological conditions in the Andes contribute to the formation of this distinctive variety, which differs from opals found in other regions.Appearance and Natural VariationEach tumblestone displays subtle differences in tone, ranging from pale blush pink to richer rose hues. Some specimens may include faint inclusions, natural banding, or slight tonal variations, all of which are part of the stone’s natural formation. The polished finish enhances these features while maintaining the integrity of the original material.The 10–20mm size range makes these stones ideal for collectors, small display pieces, or incorporation into curated mineral collections.Uses and Collecting AppealPeruvian Pink Opal tumblestones are popular among mineral collectors, gemstone enthusiasts, and those seeking naturally formed decorative stones. Their soft colour and smooth finish make them suitable for display, gifting, or inclusion in curated crystal sets.In cultural and non-scientific contexts, pink opal is traditionally associated with calmness and emotional balance, often appreciated in spiritual settings. These associations are based on historical and cultural perspectives rather than scientific properties.Authenticity and Presentation
