AI Appraisal Estimate

This is a fine lead crystal sculpture produced by the renowned Målerås Glassworks in Sweden, specifically designed by master artist Mats Jonasson. The piece is crafted from heavy, high-quality full lead crystal characterized by its exceptional clarity and light-refractive properties. The sculpture features a combination of high-polish smooth surfaces and intricate intaglio engraving on the reverse side, a signature technique of Jonasson that creates a three-dimensional effect when viewed from the front. The edges are textured and frosted, simulating the rugged appearance of natural ice or rock. A distinctive etched signature is clearly visible on the lower section of the clear glass face, reading 'MJonasson' or 'M. Jonasson', which serves as a guarantee of authenticity and quality. This item appears to be from the late 20th century, likely the 1980s or 1990s. The condition is generally good, though there are visible light surface scratches and minor abrasions consistent with shelf wear. There are no major chips or fractures apparent in the provided view. The craftsmanship displays a high level of technical skill, particularly in the hand-finished details of the frosted base and the sharp, clean lines of the etched signature.

Based on my visual examination of the Mats Jonasson Målerås lead crystal sculpture, the piece exhibits the hallmark characteristics of Swedish high-lead content crystal, inclusive of a deep intaglio relief and a signature 'ice-rock' textured exterior. The etched signature 'M. Jonasson' aligns with mid-to-late 20th-century production marks from the Målerås Glassworks. While the craftsmanship is superior, the presence of visible surface scratches and shelf wear on the high-polish face slightly diminishes the secondary market value. The current market for Jonasson crystal is stable but saturated; these pieces were produced in significant quantities and are frequently found on the secondary market. Comparable sales for standard-sized wildlife or botanical studies typically fall within the $40 to $90 range depending on the specific motif and size. The most significant value factors here are the condition of the clear face and the clarity of the intaglio. From images alone, I cannot verify the absence of 'glass cancer' (internal clouding) or microscopic flea bites along the textured edges. A definitive authentication would require a physical inspection to verify the specific gravity of the lead crystal, a tactile examination of the signature depth, and original provenance or labeled boxing. For insurance purposes, I have valued this at a fair market replacement cost, noting that rarity is low for this specific era of Målerås production.
