Armillary Sphere Ring An intriguing high-carat gold ring, dated 1858, a deceptively simple gold band which hinges open to form a miniature version of an armillary sphere. The ring is inscribed to interior : Bertha Hess and 2 Mar 1858, no doubt to commemorate a death. The ring is size R and 1/2 [US 8 and 7/8] and cannot be sized ; it can also be worn open, hanging on a chain. The band when closed is 1/8 of an inch wide. Clever construction, immaculate condition.
A gold ring circa 1780, of interlocking hinged hoops which unfold into a miniature armillary sphere, with a crystal covered bezel containing a lock of hair. The interlocking hoops are concealed when the ring is closed. Armillary spheres were used to show the movement of the planets around the sun, but the ring would not have been usable as such and illustrates the fascination with science common in the 18th century.
