75% pure · 18/24 · hallmarked 75018K is three-quarters gold, stamped 750, and it is the usual standard for fine and designer jewellery — what the major international jewellery houses work in. A quarter of the metal is alloy, making it noticeably harder than 21K or 22K and far better at holding a polished edge.
That hardness is why gem-set pieces are usually 18K: prongs holding a diamond have to stay where they were bent, and softer gold lets stones work loose. It is also the karat that carries colour — a copper-heavy mix gives rose gold, palladium or nickel gives white gold.
Priced per gram it looks cheaper than 21K, but that is arithmetic, not a discount: you are buying a quarter less gold. Sold back, the shop pays on 75% of the weight — so compare 18K against 21K by gold content, never by the sticker.
The dominant retail karat in Thailand is 23K, so 18K is usually a deliberate choice here — bought for what it does better, not because it is what the shop happened to have.

Common questions about 18K gold in Thailand
- What is the 18K gold price today in Thailand?
- 18K gold price in Thailand is shown in THB in the table above and keeps moving while the page is open. The price is derived from the international spot ounce price (XAU/USD, from Swissquote and live PAXG/USD quotes), divided by 31.1035 grams per troy ounce, multiplied by the purity ratio (75%), and converted at the daily THB/USD FX rate.
- Does the Thailand gold price include making charges and VAT?
- No. The displayed price is the raw spot-equivalent gold value only. Jewellery shops add a making charge, which each shop sets, and their own margin.
- Why does 18K gold in Thailand differ from the global price?
- Global gold is priced in USD. The Thailand price shown here is the same global price converted to THB at the daily FX rate, then divided to a per-gram value at the 18K purity ratio. There is no real price difference — just unit and currency conversion.
- Where do I buy 18K gold in Thailand?
- Gold is sold in Thailand at local gold souks and licensed goldsmiths. Always check the hallmark stamp to confirm karat, and obtain a documented receipt. The spot price shown here is your reference for evaluating the shop's price before making charges.
- How often is the Thailand gold price updated?
- The spot price is refreshed from Swissquote at least every five minutes and moves with live PAXG/USD quotes while the page is open. The THB/USD exchange rate is the day's mid-market rate from the open-source currency-api feed. The price you see is the global spot price converted to the local currency.
