A striking example of Mexican Modernist jewelry, this vintage sterling silver convertible brooch and pendant necklace is signed Miguel and attributed to distinguished Taxco jewelry designer Miguel García Martínez, celebrated for his imaginative mixed-metal compositions and sculptural designs.

Boldly geometric and beautifully balanced, this exceptional piece combines the warmth of gold-toned metalwork with cool sterling silver, vivid turquoise accents, and a dramatic black stone (piedra negra) background to create a captivating sunburst-inspired composition.

The circular centerpiece features a brilliant turquoise-blue cabochon surrounded by concentric silver-toned borders. Six radiating gold-toned geometric bands extend outward across the contrasting dark surface, creating a dynamic architectural pattern.

Positioned between these radiating elements are six smaller silver circular medallions, each accented with a miniature turquoise-blue center and delicate engraved starburst detailing.

The interplay of warm metallic tones, brilliant blue accents, and deep black stone creates a wonderfully dramatic visual effect, reminiscent of celestial imagery and the bold geometric abstraction associated with Mexican Mid-Century Modern design.

Measuring approximately 1.9 inches in diameter, this substantial piece offers remarkable versatility. Its convertible construction allows it to be worn as an eye-catching brooch on a jacket, coat, or scarf, or suspended from the included 20-inch chain as a distinctive statement necklace.

The reverse is marked TAXCO 925 MIGUEL 058, identifying its Mexican origin, sterling silver content, and the Miguel signature associated with García Martínez.

About the Designer — Miguel García Martínez

Miguel García Martínez was an accomplished Mexican jewelry designer associated with Rancho Alegre, an important Taxco workshop established in 1956.

As a principal designer for Rancho Alegre, García Martínez contributed to the artistic evolution of Mexican studio jewelry during the mid-to-late 20th century.

His designs often embraced sculptural compositions, traditional Mexican imagery, and imaginative combinations of sterling silver, copper, turquoise, and contrasting dark materials.

His work reflects the rich artistic heritage of Taxco, where generations of talented silversmiths helped establish the region as an internationally recognized center of modern Mexican jewelry design.

Examples attributed to García Martínez are preserved in the Museum of International Folk Art in Santa Fe, New Mexico, including a convertible brooch and pendant with a closely related Miguel hallmark.
