What Is Cobalt Blue Miniature Oil Lamp Worth?

The typical price range for Cobalt Blue Miniature Oil Lamp is $30 - $45 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

How to Identify Cobalt Blue Miniature Oil Lamp?

• Check the base for 'Made in Japan' embossed marks or original paper labels common for the 1940-1960 era.
• Examine the glass for the distinct pressed mold lines characteristic of mass-produced mid-century cobalt glass.
• Verify the presence of the original brass collar and burner assembly, which should fit the small-scale threaded neck.
• Look for the deep, translucent 'cobalt' blue hue that remains consistent throughout the glass body.
