Troezo — Gold and Silversmithing

Troezo (Dzongkha: khro bzo or bro bzo, "ornament craft") is the traditional art of gold and silversmithing in Bhutan, classified as one of the Zorig Chusum, the thirteen traditional arts and crafts. Troezo encompasses the working of gold, silver, and copper into jewelry, ritual objects, ceremonial implements, and decorative items. The craft has historically served three interconnected spheres of Bhutanese life: Buddhist religious practice, which requires a wide range of consecrated metal objects; court and official ceremony, which demands regalia and insignia of rank; and personal adornment, which in Bhutan carries both aesthetic and social meaning.

Bhutanese goldsmiths and silversmiths are among the most technically accomplished metalworkers in the Himalayan region. Their repertoire includes hammering and raising (shaping metal by hammering it over forms), repoussé (pushing designs out from the back of a metal sheet), chasing (refining details from the front), engraving, filigree (creating lace-like patterns from fine wire), granulation, stone setting, and gilding. The combination of these techniques produces objects of remarkable intricacy and beauty.

Historical Background

Precious metalworking in the Himalayan region has deep roots, with Nepal's Newar goldsmiths and Tibetan metalworkers establishing traditions that influenced Bhutanese practice. Trade routes through the Himalayas brought gold, silver, turquoise, coral, and other materials into Bhutan, while Buddhist patronage — from monasteries, aristocratic families, and eventually the state — sustained a demand for high-quality metalwork.

The 17th century consolidation of Bhutan under Zhabdrung Ngawang Namgyal intensified demand for precious metalwork. The new dzong-based administration required official insignia, ceremonial objects, and gifts for religious and diplomatic occasions. Royal and aristocratic patronage supported workshops where master goldsmiths produced objects of the highest quality, some of which survive in temple treasuries and museum collections.

Certain regions of Bhutan became particularly associated with Troezo. The town of Trashi Yangtse in eastern Bhutan is renowned for its metalwork tradition, and silversmiths in the Bumthang valley have long been recognized for their skill. The craft was traditionally practiced by specific families and communities, with techniques passed down through generations.

Techniques

Hammering and Raising

The most fundamental metalworking technique, hammering (or raising), involves shaping a flat sheet of metal into a three-dimensional form by striking it over a stake or form with hammers of various shapes. Bhutanese smiths use this technique to create bowls, cups, butter lamp holders, and the basic forms of larger objects. The metal must be annealed (heated and slowly cooled) periodically during the hammering process to prevent it from becoming brittle and cracking.

Repoussé and Chasing

Repoussé is the technique of creating raised designs by pushing metal outward from the back of a sheet, using punches and hammers while the metal rests on a yielding surface (traditionally a bed of pitch or leather filled with sand). The complementary technique of chasing refines the design from the front, adding detail and definition. Together, these techniques produce the relief decoration found on ritual vessels, jewelry, and architectural ornaments.

Filigree

Filigree — the creation of delicate, lace-like patterns from fine gold or silver wire — is one of the most distinctive and demanding techniques in Bhutanese metalwork. Fine wire is drawn, twisted, coiled, and soldered into intricate designs that are then attached to a base or assembled into freestanding structures. Bhutanese filigree is applied to jewelry, decorative boxes, scabbards, and ritual objects, creating a texture of extraordinary delicacy.

Engraving and Inlay

Engraving involves cutting designs directly into the metal surface using sharp steel tools called gravers or burins. Bhutanese engraving ranges from simple inscriptions of mantras to elaborate decorative patterns. Inlay techniques — setting one metal into another (such as gold wire into a silver ground) — are used for decorative contrast on sword hilts, jewelry, and ritual implements.

Stone Setting

Bhutanese jewelry traditionally incorporates turquoise, coral, agate, and other semi-precious stones, set using bezel settings (a strip of metal wrapped around the stone) or prong settings. Turquoise holds particular cultural and spiritual significance in Bhutan and across the Himalayan world, symbolizing the sky and believed to offer protection. Coral, imported through trade networks from the Indian Ocean, represents life force and auspiciousness.

Principal Products

Jewelry

Bhutanese jewelry includes rings, earrings, necklaces, bracelets, brooches (koma, used to fasten the kira), pendants, and amulet boxes (gau). The koma — a pair of ornate brooches joined by a chain, used by women to secure their national dress at the shoulders — is perhaps the most characteristically Bhutanese piece of jewelry. Koma range from simple silver pieces to elaborate gold and turquoise creations, and their design and materials indicate the wearer's status and regional origin.

Gau (portable amulet boxes or prayer boxes) are another distinctive product. These hinged containers, typically oval or rectangular and made of silver or gold with repoussé decoration, are worn on a cord around the neck and contain sacred objects — small statues, consecrated pills, written mantras — that protect the wearer. The exterior is often adorned with Buddhist symbols, filigree, and set stones.

Ritual Objects

Troezo supplies many of the metal objects used in Buddhist ritual practice: offering bowls, butter lamp holders, incense burners, mandala offering plates, and ceremonial vessels. While cast bronze objects (produced through Lugzo) dominate in larger-scale ritual furnishings, smaller and more ornate pieces are often the work of goldsmiths and silversmiths using sheet metal techniques.

Swords and Daggers

Ceremonial swords (patang) carried by officials on formal occasions are among the most elaborate products of Troezo. The scabbards and hilts are covered with silver or gold sheet, decorated with repoussé, filigree, and engraving, and set with semi-precious stones. These swords are primarily objects of rank and ceremony rather than weapons, and their metalwork reflects the highest levels of the goldsmith's art.

Training

Troezo is taught at the Zorig Chusum Institute in Thimphu, where students learn the full range of techniques over a four-to-six-year programme. The curriculum covers metalworking fundamentals (hammering, annealing, soldering), decorative techniques (repoussé, filigree, engraving, stone setting), and the iconographic knowledge necessary for producing religiously correct ritual objects.

Family-based apprenticeship continues alongside institutional training, particularly in regions with strong metalworking traditions. Some techniques — notably filigree and the preparation of specific alloys — have traditionally been closely guarded family knowledge, transmitted only within lineages of practitioners.

Contemporary Practice

Gold and silversmithing continues to thrive in Bhutan, sustained by demand for jewelry, ritual objects, and ceremonial items. The growing tourist market has expanded demand for Bhutanese jewelry, while religious patronage ensures ongoing commissions for ritual metalwork. Contemporary Bhutanese goldsmiths work within the traditional framework while sometimes incorporating new materials and market-oriented designs.

Challenges include the high cost of precious metals, competition from machine-made imports, and the long training period required to master the craft. The Bhutanese government's support through the Zorig Chusum Institute and cultural preservation programmes helps maintain the viability of Troezo as both a living tradition and an economic livelihood.
