What is jewelry gold
The 96.5% Thai standard for ornaments — purity, weight, and the cost of being shaped
Definition
Jewelry gold — ทองรูปพรรณ in Thai — is gold that has been worked into ornamental form: necklaces, rings, bracelets, pendants, earrings. Thailand standardises on 96.5%-pure gold for both jewelry and bullion, which means the gold content is directly comparable between forms. The word รูปพรรณ comes from Pali-Sanskrit roots meaning shape and form — distinguishing it from ทองคำแท่ง (bar gold), which is not worked. Jewelry is priced by gold weight plus a workmanship fee for the shaping.
Fineness of the gold
The 96.5% figure means 96.5 parts of every 100 by weight is pure gold; the remaining 3.5% is an alloy of copper, silver, or zinc added to harden the metal. Pure 99.99% gold is too soft for daily-wear jewelry — it scratches and deforms easily. International markets often use 18-karat (75%) or 22-karat (91.6%) for jewelry, but Thailand uses the same 96.5% standard for both ornaments and bar gold. That single-standard simplification lets buyers compare prices directly between forms — something most other markets can't offer.
Thai weight units
Gold weight in Thailand is measured in baht and saleung, not grams: 1 baht = 4 saleung = 8 fueang. For jewelry, 1 baht weighs 15.16 grams; for bar gold, 1 baht weighs slightly more at 15.244 grams (the official standards differ marginally). A 1-saleung (¼-baht) jewelry piece weighs about 3.79 grams — a common size for small rings and pendants. Larger pieces, like thick chains or heavy bangles, are usually 1 baht or more; the largest commonly traded sizes are 5–10 baht.
What you pay at purchase
The price displayed on a jewelry piece combines: (gold value at the published 96.5% reference rate) + (workmanship fee) + (dealer margin). For a 1-baht jewelry piece in May 2025, the gold value was roughly ฿62,000, with the standard ฿800 workmanship fee plus ฿100–300 dealer margin, totalling around ฿63,000–฿63,200 at the shop. Prices are generally not negotiable for retail purchases — only larger quantities or bespoke commissions tend to leave room for discussion.
What you recover on resale
When you sell jewelry back, the dealer pays the published bar buy-back reference price of the day — the value of the 96.5%-pure gold only, not the workmanship. The dealer melts your piece back into raw stock; the design is irrelevant to them. For a 1-baht jewelry piece at a ฿62,000 buy-back price, you receive ฿62,000, losing the ฿800 workmanship paid at purchase. Some shops deduct another ฿50–200 for testing and verification, depending on condition.
When jewelry is worth it, and when it isn't
Jewelry is worth it when you actually want to wear or gift the piece — the workmanship is the cost of having an object, not just metal. Jewelry is not worth it when the goal is saving or speculating on gold prices — the workmanship is a sunk cost unrecoverable on resale. For pure gold savings, bar gold delivers better net returns every time, especially over short 1–5 year holds where price appreciation hasn't had time to offset the workmanship loss.
