Subject Description

The outer rim shows the characteristic respiratory pores of the species.
Condition & Value Assessment
Condition Assessment
Good; the nacre appears vibrant, though there is some visible calcification and natural wear around the edges and within the central scar.
Estimated Market Value
$15 - $45 USD
Auction Estimate
$10 - $30 USD (typically sold in decorative or mineralogical lots)
Provenance History
Likely sourced from coastal regions (e.g., New Zealand, California, or South Africa); typical of specimens sold in souvenir, decor, or metaphysical shops.
Art Historical Significance
While a natural object, abalone nacre (Mother of Pearl) has been used globally for millennia in inlay work (e.g., Maori carvings, lacquerware). As a standalone object, it represents the intersection of marine biology and home decor during the late 20th to early 21st century.
Notable Features
High-intensity green and teal iridescence in the lower-left section; well-defined respiratory pore line; prominent central attachment scar.
Condition Issues
Minor edge chipping; some dulling of the nacre in the lower quadrant; organic residue within the respiratory pores.
Conservation Recommendations
Avoid acidic cleaners or prolonged exposure to direct sunlight, which can dehydrate the shell and lead to brittleness or loss of color. Clean with a soft, dry cloth.
