Frequently Asked Questions

We stock investment-grade physical gold and silver:

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

We also buy gold jewellery and gold scrap. If there's a specific product you're after, just ask — we can source most mainstream bullion.

Bullion is physical gold or silver valued primarily by its metal content and purity rather than by 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 — slightly heavier than the everyday (avoirdupois) ounce of 28.35 grams.

Most of the bars and coins we sell qualify as Investment Precious Metals (IPM), which have been exempt from GST in Singapore since October 2012. To qualify, metal must meet minimum purity standards (gold 99.5%, silver 99.9%, platinum 99%), be tradeable internationally and be priced based on the metal's spot value. Singapore also has no capital gains tax, so qualifying investment bullion can be bought and sold without GST or capital gains tax.

Authenticity is central to what we do. Items at our store are verified using a Sigma Metalytics PMV Pro, which confirms a piece is solid, genuine metal without damaging it. When you buy from us, your bullion is checked before it reaches you; when you sell to us, we authenticate on the spot so you have full confidence in every transaction.

Gold and silver trade on live global markets, so quoted prices move throughout 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, usually quoted in US dollars per troy ounce. It's set continuously by major markets in London, New York and Asia, and 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.

Physical metal carries a small premium over spot to cover refining, minting, transport, insurance and handling. Premiums vary by product, brand, size and availability — larger bars generally carry a lower premium per ounce than small bars or coins. The premium is simply the cost of owning real, tangible metal in your hand rather than a paper claim.

We accept PayNow, bank transfer and credit card.

Credit card payments (Visa / Mastercard / Amex) are subject to additional processing fees, in-store and online:

• Domestic (Visa / Mastercard / Amex) — 2.9%
• International — 3.9%
• WeChat — 1.5%

For anti-money-laundering reasons, payment should come from an account in your own name that matches your order. Third-party payments — from another person, company or trust that isn't the account holder — can't be accepted. If you're buying through a company or trust, the payment should come from that entity's account.

Payment is completed at checkout using your preferred method, right after your price locks. Because your price is only held for 10 minutes against a moving market, prompt payment keeps your locked price valid.

Yes. We run an active buyback program and regularly purchase investment-grade gold and silver — bars and coins — regardless of where you originally bought them. We also buy gold jewellery and scrap. Our buyback prices are based on the live spot price with no hidden fees, and we aim to pay more than the larger dealers on comparable items.

Let us know 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 payment is made promptly by bank transfer to an account in your name. Jewellery and scrap are assessed for weight and purity before we confirm the final price.

Yes. As a Regulated Dealer we're required to verify identity on buyback transactions, so we'll 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.

You can receive your payment through either PayNow or bank transfer within 2 business days. Please contact us if you would like to sell your bars or jewellery.

Every order is packed in a fitted sleeve for protection, with a care card explaining how to look after your metal and a QR code linking to our community channels. It's presentation you'll be proud to keep — or to give.

We reward loyalty through membership tiers and store credit, so the more you buy over time, the more value you unlock on future orders.

Absolutely. Our referral program rewards you with store credit when someone you refer makes a purchase. Reach out for your referral details.

Yes. Big Bullion operates as a Regulated Dealer under Singapore's regime for precious stones and precious metals dealers. That means we maintain proper anti-money-laundering (AML) and know-your-customer (KYC) procedures and keep records as required by law.

Customer due diligence protects everyone. Identity verification helps prevent money laundering, terrorism financing and fraud, and it's a legal requirement for Regulated Dealers in Singapore. We handle your personal data in line with Singapore's Personal Data Protection Act (PDPA) and use it only for compliance and completing your transaction.

Yes. Any identification or personal details you provide are collected, used and stored strictly for compliance and to fulfil your order or buyback, in accordance with the PDPA. We don't share your information for marketing without your consent.
