BANDED GUARANI SANDSTONE FRAGMENT (40.5 ct) – ROUNDED AND POLISHED | HANDCRAFTED WIRE-WRAPPED PENDANT & STAINLESS STEEL DIFFUSER NECKLACE

An exclusive LAZZERINI-GEOJOIAS creation from the PIRAGEM, ROCHA, and AROMATHERAPY collections. This signature "Geo-jewelry" piece features a natural, rounded, and polished fragment (~40.5 ct) of Guarani Sandstone—an oval-shaped stone banded in beige and purple. It was hand-collected in very limited quantities with environmental preservation in mind in Piracicaba, São Paulo, Brazil. The stone is encased in a handcrafted wire-wrapped metal pendant and suspended from an American-style link chain; both are made of jewelry-grade stainless steel. Together, they transform a sedimentary rock—approximately 275 million years old—into a sophisticated, elegant, functional, and one-of-a-kind accessory.

A precious tribute to this geological heritage site and groundwater reservoir: "The Guarani Aquifer."

DESCRIPTIONS

Sandstone is classified as a sedimentary rock and a type of gemstone, rather than a single crystalline species.

. Sandstone sedimentary rock, composed of quartz, feldspar, rock fragments, cement, and a silt-clay matrix. Its grain size ranges predominantly from fine to medium sand. It commonly exhibits plane-parallel stratification—highlighted by alternating laminae varying in clay and silt content—or medium-to-large scale tangential cross-stratification.

. Formed through deposition in humid aeolian paleo-environments during the late Permian and early Triassic periods (~250 million years ago). It is part of the Paraná Volcano-Sedimentary Basin and is geologically designated as the Pirambóia-Botucatu Formation.

WHY THIS GEO-JEWELRY PIECE IS SPECIAL

. Original Brazilian design: highlighting the crystals while preserving the rock's natural texture and laminations; handcrafted using original wire-wrapping techniques and a jewelry-grade stainless steel chain.

. A rock of transnational, national, and regional geological, historical, cultural, and economic significance.

. Primary material: Guarani Sandstone, associated with the largest freshwater aquifer in the Americas.

. Origin: Piracicaba, São Paulo, Brazil; sourced from an outcrop in the aquifer's recharge zone.

. Carefully collected and hand-selected from nature in very small quantities—without disturbing the natural environment—from quarry tailings or public outcrops. Includes records of date and origin, certified by a geologist.

. Geological history: a record of ancient paleo-environments featuring dunes alternating with periods of seasonal moisture.

. Natural colors: shades ranging from purplish-gray to purple, with beige banding; colors may vary depending on the lighting.

. Personal diffuser: the same porosity and fluid-retention properties that make this rock an excellent aquifer also facilitate unique absorption and the gradual release of aromas.

. Authenticity: comes with a LAZZERINI-GEOJOIAS certificate of origin and authenticity, along with instructions for applying and diffusing aromatic fluids.

SYMBOLISM & TRADITIONS

. The name "sandstone" derives directly from the rock's nature: a stone composed of sand-sized particles. First described in the early 19th century, the name remains fitting, as its granular texture is often the first characteristic a collector notices.

. Metaphysical and energetic crystal properties: grounding, stability, and clarity. Chakras: Root and Sacral. Zodiac: Sagittarius, Gemini, Taurus, and Virgo. Planet: Earth. Element: Earth.

AROMATHERAPY

. Beyond its exceptional beauty as a piece of gemstone jewelry—whether worn as an accessory, adornment, amulet, or talisman—this item allows for the direct application of essential oils, colognes, and perfumes, serving as an excellent portable personal aromatherapy diffuser. Its unique composition of highly porous, sandy quartz minerals offers a dual benefit: excellent fluid absorption combined with a slow release of the scent into the surrounding air, ensuring the fragrance lingers longer.

. Carefully apply a small amount of your chosen essential oil, hydrosol, cologne, or perfume directly onto the stone using a dropper, moistening it slightly without saturating it to the point where it might stain clothing. Its porous structure absorbs the liquid and gradually releases the scent, acting as a portable personal diffuser. Aroma intensity and duration may vary depending on the product used, the quantity applied, and the environment. The dropper and fragrance are not included.
