Sapphiret (saphiret) is a highly collectable glass stone used in jewelry. It is believed that the glass was initially made in the mid to late 19th century in the Gablonz, region of Bohemia (Now the Czech Republic), Germany, as well as several other European countries. Quite distinctive as its color changes from a mauve brown to aqua blue which reflects an iridescence or soft blue glow when exposed to light. It is made by mixing melted gold into a basic sapphire-colored glass. The rising cost of gold over the years led to the termination of its manufacture.

This particular example of the glass is especially large and features a lively color with strong blues and mauves. Square cut and faceted, the 15 mm by 15 mm saphiret is set in a two-part articulated earring of vermeil silver. Suspended from a later date 10k yellow gold ear wire with globe, the pendant is oriented in a lozenge or rhombus form which is well suited to catch the light so important for the color-changing characteristic. Most Saphiret was set in metal, so especially prized here in gilded silver.
