Crafted in \u003cstrong\u003e18k gold\u003c\/strong\u003e, the pendant is built around a stepped square motif, architectural in spirit and meticulously balanced.\u003c\/div\u003e\n\u003cdiv\u003eAt its center lies a \u003cstrong\u003eblack onyx baguette-cut element\u003c\/strong\u003e, its deep, velvety tone anchoring the design. Flanking the onyx are panels of luminous \u003cstrong\u003emother-of-pearl\u003c\/strong\u003e, whose soft iridescence introduces light and subtle color play—an elegant counterpoint to the darkness of the onyx.
