Larvikite Crystal Egg Polished Norwegian Larvakite Feldspar Stone Genuine Specimen with Certificate of Authenticity
£ 20.40
LARVIKITE CRYSTAL EGG – POLISHED NORWEGIAN LARVAKITE FELDSPAR STONEThis Larvikite Crystal Egg is a genuine polished specimen of larvikite, often
commercially referred to as “Larvakite,” a striking igneous rock prized for its shimmering feldspar crystals. The photograph shows the exact egg you will receive, carefully selected for its pattern, flash, and finish. Full sizing details are available in the listing photos. Your specimen includes a Certificate of Authenticity lifetime guarantee generic card, confirming it as a genuine natural stone. GEOLOGICAL CLASSIFICATION & MINERAL COMPOSITIONLarvikite is an intrusive igneous rock primarily composed of feldspar minerals, particularly ternary feldspar (a mix of potassium, sodium, and calcium feldspar), with additional minerals such as nepheline, biotite, and amphibole commonly present. It formed during the Permian period, approximately 290 million years ago, within the Larvik Plutonic Complex in southern Norway.Although often described in the crystal trade as a single mineral, larvikite is technically a rock rather than a single crystal species. Its most notable visual feature comes from the feldspar crystals embedded within the darker matrix. These feldspars belong to the triclinic crystal system and are responsible for the stone’s distinctive reflective effect. OPTICAL EFFECT & APPEARANCELarvikite is highly valued for its iridescent flashes, sometimes described as labradorescence-like, though technically distinct. This optical phenomenon is caused by light reflecting from microscopic intergrowths within the feldspar crystals. Depending on the angle and lighting, the surface may display silvery blue, steel grey, or subtle bluish flashes against a darker grey to black background.The egg shape enhances this reflective quality, as the curved, polished surface allows light to move smoothly across the feldspar crystals. The finish is smooth and glossy, emphasising both the crystalline structure and the contrast between matrix and feldspar. EGG SHAPE & CRAFTSMANSHIPCarved into a classic egg form, this larvikite specimen combines geological interest with decorative appeal. The egg shape has long been used in lapidary work to highlight natural patterns and create a tactile, balanced display piece. The symmetrical carving allows the internal mineral structure to be appreciated from every angle.The surface has been expertly polished to bring out the stone’s natural sheen and reflective inclusions while maintaining the integrity of the mineral structure. LOCALITY & GEOLOGICAL SIGNIFICANCELarvikite is strongly associated with the Larvik region of Norway, where it is quarried both as a decorative building stone and for lapidary purposes. It is sometimes marketed in the architectural trade as “Blue Pearl Granite,” though it is geologically distinct from true granite.The stone’s formation within deep-seated magma chambers allowed slow cooling, enabling the growth of visible feldspar crystals. This slow crystallisation is what produces the characteristic large feldspar grains responsible for its visual appeal. TRADITIONAL & SPIRITUAL ASSOCIATIONSLarvikite is traditionally associated in spiritual practices with grounding and protection. Many people incorporate it into meditation spaces or crystal displays for symbolic purposes. These associations are cultural and belief-based rather than scientific. IDEAL FOR COLLECTORS & DISPLAYThis Larvikite Crystal Egg makes an attractive addition to any mineral collection, modern interior setting, or geological display. Its natural iridescence and Norwegian geological origin make it especially appealing to collectors of feldspar-rich stones and decorative igneous rocks.You will receive the exact specimen shown in the photographs, securely packaged and presented with a Certificate of Authenticity lifetime guarantee card. A genuine polished larvikite egg, selected for quality, structure, and visual character.
