Tulip-shaped stemware with cobalt blue base Accents

This item appears to be a clear glass goblet or wine glass featuring a distinct tulip-shaped bowl with a slightly flared rim. The lower portion of the bowl is integrated with a deep cobalt blue color, creating a gradient effect where the blue transitions into clear glass. It is supported by a slender, clear glass stem and a standard circular foot. The construction is consistent with modern machine-blown or hand-finished glass techniques often seen in contemporary tabletop decor. The glass appears thin and elegant, suggesting a decorative or formal use. No visible maker's marks, signatures, or etched labels are identifiable in the image, meaning an attribution to a specific manufacturer like Mikasa or Villeroy & Boch (whose styles this piece may resemble) is speculative and would require in-person inspection of the base for a mark. The item appears to be in good condition with no visible chips or cracks, showing typical clarity for lead-free or crystalline glass. This style is consistent with late 20th-century or early 21st-century production.

I have examined the image of this tulip-shaped glassware, which features a clear bowl and a cobalt blue transition at the base. From what I can see, the piece displays a modern aesthetic consistent with late 20th or early 21st-century production. The quality of the glass appears to be lead-free crystal or high-grade soda-lime glass, though I cannot verify the exact material composition or weight without a physical inspection. Based on the visual evidence, the item resembles styles produced by manufacturers such as Mikasa or Villeroy & Boch; however, I must treat this attribution as a hypothesis only. There are no visible maker's marks or signatures in the photograph, and a physical examination of the base would be necessary to identify any etched brand labels. My valuation range of $15 to $35 represents the typical market behavior for single stems of this quality if attributed to a known mid-tier designer brand. If the piece were to be identified as a generic mass-market reproduction or an unbranded 'in the style of' piece, the value would likely decrease to the $5 to $10 range. The market for decorative cobalt-accented stemware remains stable for replacement sets, though individual pieces have limited upside. To strengthen this appraisal, I would need to perform an in-person inspection to check for micro-etchings and evaluate the clarity and refractive index of the glass. Authentication would require comparing the specific dimensions and transition geometry against known manufacturer catalogs or provenance documentation.
