Black Amethyst Glass Vase Value Guide

This Black Amethyst Glass Vase is a quintessential example of American Art Deco glassware, prized for its sleek, opaque appearance that mimics true obsidian. Its collectible appeal lies in the unique chemical composition where manganese dioxide creates a deep purple translucency visible only when backlit.

What Is Black Amethyst Glass Vase Worth?

The typical price range for Black Amethyst Glass Vase is $25 - $30 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the glossy surface, as scratches or 'flea bites' significantly impact the $25-$30 price point.
• Intensity of the purple hue when illuminated, with deeper amethyst tones often being more desirable.
• Presence of original manufacturer labels or identifiable mold patterns from prominent US glass houses.
• Structural integrity of the flared neck, ensuring no chips or clouding from internal mineral deposits.

How to Identify Black Amethyst Glass Vase?

• Hold the vase up to a strong light source to confirm a deep violet or plum glow rather than true black.
• Examine the surface for the characteristic high-gloss, smooth finish typical of 1930s-1950s American production.
• Check the base for a polished pontil mark or specific maker's marks common to US manufacturers of the era.
• Verify the classic bulbous body and flared neck silhouette which aligns with mid-century decorative trends.

History of Black Amethyst Glass Vase

Black Amethyst glass, a deep violet glass that appears completely black under normal light, rose in popularity during the early 20th century. While it looks like true obsidian, holding it up to light reveals its deep purple hue, a result of adding manganese dioxide to the glass mixture. It was widely produced by American glass companies for functional and decorative wares, appealing to the streamlined aesthetic of the Art Deco period and beyond.
