Sunstone Obelisk Point Natural Feldspar Crystal Aventurine Effect Genuine Mineral Specimen with Certificate of Authenticity
£ 18.00
SUNSTONE OBELISK POINT – NATURAL FELDSPAR CRYSTAL WITH AVENTURINE EFFECTThis Sunstone Obelisk Point is a genuine natural feldspar mineral specimen,
carefully carved and polished into a classic four-sided obelisk shape. The photograph shows the exact piece you will receive, selected for its warm colour tones, reflective inclusions, and smooth finish. Full sizing details are available in the listing photos. Your crystal includes a Certificate of Authenticity lifetime guarantee generic card, confirming it as an authentic natural mineral specimen. MINERAL TYPE & CRYSTAL STRUCTURESunstone is a variety of feldspar, most commonly belonging to the plagioclase or orthoclase feldspar groups. Its chemical composition generally falls within the sodium-calcium aluminium silicate range for plagioclase feldspars or potassium aluminium silicate for orthoclase varieties. Feldspars crystallise in the triclinic or monoclinic crystal systems depending on the specific species.The defining optical feature of sunstone is aventurescence, a glittering effect caused by light reflecting off tiny plate-like inclusions within the stone. These inclusions are often composed of hematite, goethite, or copper particles. When light strikes the polished surface, the internal inclusions produce a sparkling or shimmering appearance that shifts with movement.Sunstone typically measures around 6–6.5 on the Mohs hardness scale and displays a vitreous to slightly pearly lustre when polished. OBELISK SHAPE & CRAFTSMANSHIPThis specimen has been shaped into a four-sided obelisk with a defined pointed apex and flat base for stable display. The obelisk form enhances the visual impact of the stone’s aventurescent effect, allowing light to interact across multiple polished faces.The smooth finish highlights the internal reflective inclusions, which may appear as golden, coppery, or reddish flashes depending on the mineral composition and lighting conditions. Each face reveals unique internal structures and natural variations in colour distribution.No two sunstone obelisks are identical, as the pattern and density of inclusions vary naturally within the feldspar matrix. GEOLOGICAL FORMATIONSunstone forms in igneous environments, particularly within basaltic or pegmatitic rocks. During crystallisation, metallic or iron-rich inclusions become trapped within the feldspar structure. As the host mineral cools and solidifies, these inclusions align in thin platelets, creating the characteristic aventurescent shimmer.Notable deposits of sunstone are found in regions such as India, Norway, Russia, Tanzania, and the United States, including Oregon, which is known for copper-bearing varieties.Associated minerals may include quartz, other feldspars, and mica within the host rock. PHYSICAL & VISUAL CHARACTERISTICSSunstone ranges in colour from pale peach and champagne to deep orange, reddish-brown, or golden hues. It is generally translucent to opaque, depending on inclusion density and mineral purity.Under direct light, the polished obelisk displays a noticeable sparkle as the aventurescent inclusions reflect light. This effect creates a dynamic appearance that changes subtly with viewing angle.Natural inclusions and faint internal fractures are characteristic of authentic feldspar specimens and contribute to each piece’s individuality. TRADITIONAL & CULTURAL ASSOCIATIONSSunstone has been used historically in jewellery and ornamental carvings. In symbolic traditions, it is sometimes associated with vitality and warmth in spiritual contexts. These associations are cultural and belief-based rather than scientific. IDEAL FOR COLLECTORS & DISPLAYThis Sunstone Obelisk Point makes a vibrant addition to any mineral collection or decorative arrangement. Its warm tones and shimmering inclusions create an eye-catching focal point suitable for display in homes, offices, or curated crystal collections.You will receive the exact specimen shown in the photographs, securely packaged and presented with a Certificate of Authenticity lifetime guarantee card.
