Celtic-Style Cruciform Cross Pendant Necklace

This is a detailed costume jewelry necklace featuring a large, ornate cross pendant with Celtic-inspired design elements. The piece is constructed from a yellow gold-toned metal and features a central rectangular emerald-cut light blue stone, likely glass or crystal. The cross is further accented by smaller round blue stones at each of the four terminals and a vertical arrangement of clear rhinestones along the arms. The design incorporates a nimbed or circular element surrounding the intersection of the arms, reminiscent of a Celtic high cross structure, detailed with openwork and textured stamping. The metal shows a bright finish with some darker patina or tarnish in the recessed areas, which highlights the decorative scrollwork and beaded borders. The pendant is suspended from a double-strand rope chain, also in a matching gold tone. No specific hallmark is immediately visible in the frontal view, but the craftsmanship suggests mid-to-late 20th-century costume jewelry manufacturing, possibly in the style of designer brands like Trifari or Sarah Coventry. The overall condition appears good with all stones intact, though there is minor surface wear consistent with age and occasional use.
