AI Appraisal Estimate

This pair of clear pressed glass plates features a striking starburst or sunburst geometric motif, characteristic of the 'Sandwich' pattern popularized by Tiara Exclusives. Each platter displays a complex radial design starting with a tight central starburst known as a 'daisy' or 'mandal' center, which extends outward into sharp, elongated lanceolate rays. The glass is clear with a slight brilliance, suggesting a high-quality soda-lime composition. The pieces are circular with smooth, slightly upturned rims and likely measure approximately 10 to 12 inches in diameter. The construction technique is mold-pressed, typical of mid-20th-century American glassware production, specifically dating between the 1970s and 1990s. The repetitive 'fan and diamond' style facets are designed to catch and refract light efficiently. Regarding condition, the surfaces appear clear of major chips or deep cracks, though minor utensil marks or light shelf wear on the base may be present upon closer tactile inspection. No visible maker's marks are apparent, which is standard for Tiara's distribution of Indiana Glass Company molds. The uniform clarity and lack of significant amber or green tinting indicate well-preserved specimens of this collectible decorative tableware.

I have conducted a visual inspection of this pair of clear Tiara Exclusives platters in the 'Sandwich' pattern. These pieces, manufactured by the Indiana Glass Company for Tiara between the 1970s and 1990s, exhibit the classic mold-pressed quality of the era. The Daisy-in-Diamond or starburst motif is sharp, with the characteristic lanceolate rays and fanned edges that define this pattern. Based on the images, the glass displays excellent clarity without the cloudiness or 'sick glass' syndrome often found in poorly stored specimens. Authenticity is consistent with known Tiara reproductions of early 19th-century Boston & Sandwich designs; the absence of a maker's mark is typical for this line. The market for mid-century Tiara glass remains stable but common. While these platters are beautiful and functional, they are not rare. This specific clear variant was mass-produced, making it less valuable than rarer colors like amberina or cobalt blue. Current market demand is driven by collectors of 'New Depression' glass and those seeking vintage holiday serving ware. Limitations: A visual assessment cannot identify micro-chips along the pattern's sharp ridges or 'flea bites' on the base rim. In-person tactile inspection is necessary to confirm the absence of utensil scratches that diminish value. Definitive authentication of the glass composition (soda-lime vs. lead) would require a UV light test to observe fluorescence, which helps distinguish late-century Tiara runs from earlier 1920s Indiana Glass versions of the same pattern.
