Long necklace attributed to the Neiger Brothers, crafted from molded Bohemian / Czech glass beads and dating to the 1920s Egyptian Revival period.

The scarab is central to the design. An important symbol in Ancient Egyptian culture, particularly associated with renewal and the solar cycle, it became one of the most recognizable motifs of the Egyptian Revival jewelry.

Norbert and Max Neiger were among the most distinctive makers associated with Czechoslovak costume jewelry of the early 20th century.

Their business developed in Gablonz, now Jablonec nad Nisou in the Czech Republic, an important historic center of Bohemian glass and jewelry production.

Following the First World War, their workshop became particularly renowned for elaborate jewelry incorporating richly colored Bohemian molded glass and exotic decorative influences drawn from Ancient Egypt as well as Chinese and Indian art.

Total length: 35.83 in (91 cm)
Weight: 54 g (1.90 oz)

Very good overall condition. The present 925 sterling silver lobster clasp is a later replacement and is not original to the necklace.

French bracelet attributed to Mithé Espelt, circa 1950. Glazed ceramic with gilt decoration.

The volumes, thick ceramic links, unglazed earthenware backs and its distinctive color palette is typical of Espelt’s work.

Mithé Espelt rarely signed her jewelry, making stylistic and technical analysis essential for attribution.

Born Marie-Thérèse Espelt (1923–2020) in Lunel, Camargue, Mithé Espelt entered the Montpellier School of Fine Arts at just sixteen years old, studying drawing and sculpture before moving to Paris after World War II.

There she collaborated with ceramic artist Émilie Decanis and also created pieces for the fashion house Lanvin. In 1946 she returned to Lunel, establishing her own workshop within the Hôtel de Bernis.

Over the following four decades she developed a unique body of work, inspired by the flora and wildlife of the Camargue, including mirrors, jewelry, decorative boxes, trays, vases and ceramic objects distinguished by brilliant enamels, genuine gold decoration and refined craftsmanship.

Although her production remained relatively discreet during her lifetime, Mithé Espelt is now internationally celebrated.

Length: 7.48 in (19 cm)
Width: 1.26 in (3.2 cm)

Excellent condition.
