Triangular-Cut Diamond and Gold Pendant Setting

The image displays two distinct jewelry components: a loose triangular-cut diamond and a gold-toned pendant or bail. The diamond is a brilliant, triangular (trillion or trilliant) cut stone, exhibiting a light yellowish tint, suggesting a color grade typically in the G-J range. Its facets are visible, reflecting light unevenly due to the low-resolution image, but betraying no obvious chips or large inclusions. The size appears relatively small, suitable for a pendant or accent stone. The metallic component is a gold-colored pendant or bail, designed to hold a gemstone. It features a basket-like setting with a V-shaped or pointed prong structure, clearly intended to secure a triangular stone like the one shown. The metal exhibits a warm, polished yellow hue, consistent with gold or gold-plated material, and shows some reflections, indicating a smooth surface. There are no visible maker's marks or stamps on either component. The overall condition appears good, with no obvious signs of significant wear, tarnish, or damage. The pieces are distinct and separate, suggesting they are either awaiting assembly or have been disassembled. Given the components, it likely dates from the latter half of the 20th century to the present, as trillion cuts became more popular. The craftsmanship appears standard for commercial jewelry, offering a clean, functional setting for the stone.
