Crystal stemware base with etched mark consistent with Waterford

This image displays the circular foot or base of a piece of fine crystal stemware, held by a hand to reveal an acid-etched marking. The foot is made of clear, colorless glass and features a multi-point starburst or sunburst cut design on the underside, which is characteristic of high-quality cut crystal. Near the edge of the rim, there is a small, frosted acid-etched mark that appears to be a stylized seahorse emblem. This specific mark is stylistically consistent with the logo used by Waterford Crystal, though its presence alone cannot be considered proof of origin without physical verification of the glass's lead content, resonance, and weight. The glass appears to be in good condition with no visible chips or cracks along the polished rim. The owner notes this mark is etched in the glass at the bottom, which is a standard location for such brand identifiers. Because marks can be acid-etched after production or replicated, this attribution remains a hypothesis subject to a professional in-person appraisal. The craftsmanship suggests a late 20th-century or early 21st-century manufacturing period for this style of luxury glassware.

Based on the provided image, I have examined a circular crystal base displaying a starburst cut and an acid-etched marking. The foot bears a mark consistent with the seahorse logo associated with Waterford Crystal. Per the user's submission, this mark is located on the bottom of the glass. While the craftsmanship appears consistent with high-quality luxury glassware from the late 20th century, I cannot verify the lead content, weight, or resonance from a photograph. Therefore, the attribution to Waterford remains a hypothesis. My estimate of $40 to $120 assumes the item is a single stem from a sought-after pattern in excellent condition; however, secondary market demand for crystal varies significantly by pattern rarity. If this piece were found to be a reproduction or a lesser-known brand 'in the style of' luxury Irish crystal, the value would likely decrease to a decorative range of $10 to $25. To move beyond this working assumption, a physical inspection is required to check for 'flea bites,' surface wear, and to confirm the hallmark's application method. This valuation is based on general market behavior for identified luxury stemware and would be more precisely determined once the specific pattern is identified and the piece is authenticated through in-person examination of the glass's clarity and refractive properties. The current market for fine crystal is selective, with collectors prioritizing well-maintained, name-brand sets over individual unverified pieces.
