Cobalt blue cased-to-clear cut glass trumpet vase

This object is a trumpet-style vase crafted from what appears to be cased glass, featuring a deep cobalt blue outer layer cut away to a clear interior. The design consists of elongated vertical wedge cuts that taper toward the base, interspersed with three rows of circular 'thumbprint' or faceted cuts near the bottom. The top rim is finished with a scalloped, serrated edge. The vessel is supported by a clear, wide circular foot. The owner has attributed this piece to T. Stabland, though no signature or maker's mark is visible in the provided image to verify this claim; identification is based purely on stylistic and material characteristics consistent with mid-to-late 20th-century European art glass. The glass appears to have high clarity and sharp, well-defined faceting indicative of quality craftsmanship. The condition appears to be good with no obvious chips or cracks visible, though physical inspection would be required to rule out minor surface abrasions or base wear. The overall aesthetic is consistent with Scandinavian or Continental crystal traditions.

I have examined the digital image of the cobalt-to-clear cased glass vase. The object displays characteristic features of high-quality European crystal, including deep vertical mitre cuts and stacked thumbprint facets. Per the user submission, this piece is attributed to T. Stabland. While the design is consistent with mid-to-late 20th-century Scandinavian glass traditions, I cannot verify this attribution from the photo alone, as no signature or acid etch mark is visible. My valuation assumes the owner's attribution is correct. Based on what I can see, the glass possesses high clarity and sharp edges, suggesting a quality manufacturer. The value of $150–$325 reflects the current secondary market for mid-century European art glass of this scale and complexity. Demand for cased cobalt glass remains steady among collectors of 'Bohemian' style or Scandinavian crystal, though prices are highly sensitive to maker identification. I cannot verify the physical condition through a photograph; a professional in-person inspection would be required to rule out flea bites, shelf wear, or internal bruising, all of which would decrease the value. Furthermore, if the piece is not by T. Stabland but is instead an unattributed 'in the style of' production or a later mass-market replica, the value would likely fall to the $40–$75 range. To increase confidence in this appraisal, I recommend obtaining provenance documentation or an expert physical examination to locate a signature or mark. The provided estimate is a working hypothesis based on the assumption of a specific maker; the absence of a confirmed mark necessitates a conservative range.
