Frequently Asked Questions

We stock investment-grade physical gold and silver:

• Gold and silver bars in a range of sizes. They come from LBMA-recognised refiners such as PAMP Suisse, Argor-Heraeus, Perth Mint and Heraeus.
• Bullion coins from major sovereign mints, such as the US Mint and others.

We also buy gold jewellery and gold scrap. Jewellery has to be gold, so we do not buy silver jewellery. If there's a particular product you're after, just ask, because we can source most mainstream bullion.

Bullion is physical gold or silver valued for its metal content and purity rather than for any collectible or artistic value. Prices are quoted per troy ounce ("oz"), the international standard for precious metals. One troy ounce is about 31.10 grams, a little heavier than the everyday avoirdupois ounce of 28.35 grams.

Singapore's GST is 9%, and has been since 1 January 2024. Metal that counts as an Investment Precious Metal is exempt, so a qualifying bar costs you the price on the ticket and nothing more. A bar qualifies when it is at least 99.5% pure for gold, 99.9% for silver or 99% for platinum, when its refiner is on the Good Delivery list of the London Bullion Market Association, current or former, and when the bar itself carries a mark giving the refiner and the purity. A bar made to be worn or displayed does not qualify, so a hole for a chain, or a shape such as an animal or a heart, is taxed. Coins are exempt only when they are on the IRAS list, and that list is not the same for gold as it is for silver, so we check a coin before we sell it. We are not GST-registered, so for now no GST is added to anything we sell, including jewellery and gold scrap. We will say so plainly if that changes. Every bar we sell qualifies. If you have a question about your own tax position, that one is for IRAS rather than for us.

We check every piece at our store on a Sigma Metalytics PMV Pro, which confirms it is solid, genuine metal without marking or damaging it. So when you buy from us, your bullion has been checked before it reaches you, and when you sell to us we authenticate it while you wait.

Gold and silver trade on live global markets. Quoted prices move through the day with the spot price and currency rates. Your price only becomes locked for 10 minutes once you confirm your order at the checkout page.

The spot price is the current global market price for immediate settlement of gold or silver. It is usually quoted in US dollars per troy ounce. Major markets in London, New York and Asia set it continuously. It moves with supply, demand and currency rates.

Spot prices update only while the major metals exchanges are open. Over weekends and certain public holidays the markets close, so the spot price stays unchanged until trading resumes.

Spot is the price of the metal itself on the market. Refining it, minting it, moving it, insuring it and handling it all cost money, and that is what the premium over our ask price covers. It varies by product, brand, size and availability, and a larger bar usually carries a lower premium per ounce than a small bar or a coin. So the premium is what it costs to have the metal in your hand.

Pay by bank transfer, in any currency we are taking payment in, or by PayNow. Tap Copy on any field to paste it straight into your banking app. Please pay from an account in your own name. The same Standard Chartered account also takes Canadian dollars, Swiss francs, Chinese yuan, British pounds, Hong Kong dollars, Japanese yen and New Zealand dollars by SWIFT transfer, so get in touch before sending one of those and we'll confirm the amount with you.

Online you can pay by card, Google Pay, PayNow or bank transfer. In store you can pay by card, PayNow, bank transfer, cash or trade in metal as part payment.

Paying by Visa, Mastercard or Amex carries an extra processing fee, in store and online:

• Domestic (Visa / Mastercard / Amex): 2.9%
• International: 3.9%

For anti-money-laundering reasons, payment should come from an account in your own name that matches your order. We can't accept a payment from anyone else, whether that is another person, a company or a trust. If you're buying through a company or a trust, the payment should come from that entity's account.

You pay at checkout, right after your price locks. Your price is held for 10 minutes against a moving market, so paying promptly keeps it valid.

Yes. We run an active buyback program, and we buy investment-grade gold and silver bars and coins wherever you originally bought them. We buy gold jewellery and scrap too, though jewellery has to be gold, so we do not buy silver jewellery. Our buyback prices come off the live spot price, and we aim to pay more than the larger dealers on comparable items.

Tell us what you'd like to sell and we'll quote you a price based on the current spot. Once you accept, your price is locked, we authenticate your items in person, and we pay you into an account in your own name. Below S$20,000 that goes out by PayNow or bank transfer straight away, and anything larger within two to five business days. Jewellery and scrap are weighed and tested for purity before we confirm the final price.

Yes. As a Regulated Dealer we must verify identity on buyback transactions. So we will ask for a copy of your NRIC or passport. This keeps every transaction compliant with Singapore's anti-money-laundering and record-keeping rules, and protects both sides against fraud.

Below S$20,000 we pay you by PayNow or bank transfer straight away. Anything larger goes out within two to five business days. Either way the money goes to an account in your own name, and never into somebody else's. Get in touch if you would like to sell us your bars or jewellery.

Every order is packed in a fitted sleeve to protect it, with a care card explaining how to look after your metal and a QR code linking to our community channels. It arrives in a state you would be happy to keep, or to give.

We reward loyalty through client tiers and store credit, so the more you buy over time, the better your prices and service get.
