Libbey Rock Sharpe Mid-Century Two-Tone Glass Goblets/Sherbet Cups (Green Bowl, Blue Base)
Libbey (Rock Sharpe Division) · Kitchenware > Drinkware & Glassware
Era / Decade
1960s - Early 1970s. The 'avocado green' and 'royal blue' color pairing reflects the quintessential Mid-Century Modern transition into the earthy tones of the early 70s.
Material
Pressed glass. The bowl is a textured green glass fused to a faceted geometric blue glass stem/base.
Condition
Good to Very Good. The glass shows some surface scuffing and mineral residue inside the bowls. No major chips are visible in the photo, but the textured edges often hide small 'flea bites'.
Demand Level
Moderate. MCM glassware has a steady following, though sherbet/small goblets have slightly less demand than full-sized drinking glasses or barware.
Resale Value
Estimated Resale Value
$18.00 - $28.00 (Pair) / $8.00 - $12.00 (Individual)

Description
Stunning pair of vintage Mid-Century Modern footed dessert cups or goblets. These unique pieces feature a vibrant forest green textured bowl set atop a geometric, tapered royal blue base. The pressed glass design catches light beautifully, perfect for serving sherbet, cocktails, or as decorative accent pieces. The square-ish profile and bold color blocking make them a standout for any MCM glassware collection.
Key Features
Highly desirable 'color block' or 'two-tone' aesthetic; Mid-Century Modern style; unique textured glass finish; geometric pedestal base; discontinued collectible glassware.
Authenticity Indicators
Libbey Rock Sharpe pieces often lacked permanent marks but are recognized by this specific mold and color combination. Confidence: High (widely documented MCM glassware pattern).
Flaws to Note
Cloudiness or 'dishwasher film' visible in the green portion (may require deep cleaning with vinegar); potential small chips along the sharp edges of the square base; light surface scratches from stacking.
Selling Guide
Where to Sell
Etsy (best for vintage decor enthusiasts), eBay (best for glass collectors), or a local curated vintage shop/booth.
Selling Tips
Thoroughly clean with a mix of white vinegar and water to remove mineral cloudiness. Photograph against a plain white background with light passing through the glass to highlight the two-tone effect. Use keywords like 'MCM', 'Two-Tone', 'Bi-color', and 'Pressed Glass'. Ship with heavy bubble wrap as the joint between the bowl and stem is a point of failure.
