Mixed media metal and crystal sculpture

This is a sculptural decorative art piece featuring metallic botanical forms mounted upon a natural crystal base, which rests inside a rectangular metallic tray or dish. The piece is roughly tabletop-sized, showcasing multiple upright stalks that branch out into textured, spherical starburst-like foliage clusters and taller, narrow floral spikes with textured tips. The metallic components display a dual-tone finish with golden-brown stems and greenish-patinated or verdigris-toned foliage and branching elements, suggesting a depiction of desert plants such as Joshua trees or ocotillos. The base consists of a large, rough-hewn crystalline cluster, specifically purple amethyst geode sections, providing a contrasting organic mineral foundation. The entire assemblage sits on a shiny metal tray. There are no obvious maker's marks, signatures, or stamps directly visible from this angle, and the overall construction appears to be a handcrafted decorative sculpture. The owner's unverified user-supplied notes describe the piece as a 'Brass and crystal sculpture'. The style and materials are consistent with mid-to-late 20th century or contemporary decorative mineral art, often crafted as unique artisan pieces. Condition appears generally intact with natural variations in the metal finish and mineral formation, though minor dust and patina are present consistent with display and age. The identification is based purely on visual inspection of the materials and form, without any claims of authenticity, specific artist attribution, or maker identification.

Based on the visual evidence available, I have evaluated this decorative sculpture. Per user submission: the piece is described as a 'Brass and crystal sculpture' featuring metallic botanical forms mounted upon a natural crystal base within a rectangular tray. Based on what I can see in the photo, the assemblage presents a dual-tone finish with golden-brown stems and verdigris-toned foliage, though I cannot verify from a photo the exact metal composition, maker, or period of manufacture. The current appraisal value range of $400 to $700 assumes that the materials are consistent with quality artisan brass and genuine crystal geode sections, and that the piece is a mid-to-late 20th century or contemporary decorative mineral art sculpture. General market demand for mid-century and contemporary mineral and metal decorative art remains steady among interior designers and collectors of organic-modern aesthetics, though such pieces typically trade based on decorative appeal rather than recognized designer provenance. This estimated range represents the potential value if the user's unverified description is accurate regarding the medium and type. Would need physical inspection to confirm the exact metal alloy, mineral species, and overall construction quality. If physical examination reveals the piece to be a modern reproduction, mass-produced replica, or 'in the style of' decorative item rather than a hand-assembled artisan work, the market value would likely decrease to the $150 to $300 range. To fully confirm attribution, condition, and material authenticity, an in-person examination by a decorative arts specialist, hallmark verification, and a detailed physical appraisal would be necessary.
