Cobalt Blue Teacup Appraisal

Imperial Porcelain Factory (Lomonosov) 'Cobalt Net' Teacup

This item is a porcelain teacup or coffee cup, originating from Petersburg, Russia. It features a distinctive hand-painted 'Cobalt Net' pattern, which is characteristic of the Imperial Porcelain Factory (Lomonosov Porcelain Factory) from St. Petersburg. The primary colors are a rich cobalt blue and white, with intricate detailing in 24k gold. The pattern consists of a dense network of intersecting cobalt blue lines forming diamond shapes, each intersection adorned with a golden star or dot, and with scallop-like or scale-like motifs outlined in gold, filling the spaces. The rim of the cup is generously gilded with a broad band of 24k gold, which also extends down the inside lip with a delicate scalloped or stylized wave pattern. The handle, visible on the left side, appears to be made of the same white porcelain and is likely also accented with gold. The cup's interior is a pristine white, providing a stark contrast to the exterior. Given the hand-painted nature and use of 24k gold, this piece exhibits high-quality craftsmanship, typical of luxury porcelain manufacturers. No visible chips, cracks, or significant wear are immediately apparent on the exterior from the provided image, suggesting good overall condition. Minor wear to the gilding might be present but is not clearly discernible. The construction appears refined, indicating a delicate yet durable porcelain body. The style period is consistent with production from the mid-20th century onwards when the Cobalt Net pattern gained widespread popularity.
