Right then, let’s get straight to it, no messing about. You’re asking “how many grams in an ounce” because you’re thinking of selling gold, and that’s a smart question. Knowing the answer is your first line of defence against getting a raw deal. Here in Hull, at Big Gold Jewellery & Bullion, we believe in absolute transparency, so let’s clear this up properly.

There are two types of ounces you need to know about, and only one matters for gold: the troy ounce. A standard (avoirdupois) ounce, like you’d measure sugar in, is 28.35 grams. But when it comes to precious metals like gold, silver, and platinum, the world uses the troy ounce, which is precisely 31.1035 grams. This difference is crucial, and it’s where many folks get caught out by less scrupulous buyers.

Why the Troy Ounce Matters for Your Gold in Hull

Imagine you’ve got a beautiful gold chain, maybe an old ring, or even some scrap gold. You’ve weighed it at home, and your kitchen scales say it’s one ounce. If a buyer then offers you a price based on 28.35 grams, but the global gold market (which always uses troy ounces) values it at 31.1035 grams, you’re instantly losing out on nearly three grams of gold value. That’s a significant chunk of change, especially with today’s gold prices.

This isn’t just a technicality; it’s a common trick used to pay you less without you even realising it. At Big Gold Jewellery & Bullion, we’re part of ‘The Big Gold Revolution’ in Hull – a movement for fair, honest, and transparent gold dealing. We educate every customer because we believe knowing the facts is the best way to protect your hard-earned assets.

Understanding Gold Purity: Carats and Fineness

Beyond weight, the purity of your gold is the next big factor in its value. Gold purity is measured in carats (or karats in some places) or by fineness. Pure gold is 24 carat (24K) or 999.9 fineness. Most jewellery isn’t pure gold because it’s too soft; it’s an alloy mixed with other metals to make it more durable.

• 24K Gold: 99.9% pure gold (999 fineness)
• 22K Gold: 91.6% pure gold (916 fineness – common in Indian and Middle Eastern jewellery)
• 18K Gold: 75% pure gold (750 fineness – a popular choice for fine jewellery)
• 14K Gold: 58.5% pure gold (585 fineness)
• 9K Gold: 37.5% pure gold (375 fineness – common in UK jewellery)

When you bring your gold to us at 51 Jameson Street, Hull, we’ll accurately test its purity right in front of you. We use non-destructive methods to determine the exact caratage, ensuring you get a precise valuation for the actual gold content.

The Live Gold Market: Why Today’s Price Matters (and Shifts!)

Here’s another crucial bit of information: the price of gold isn’t static. It’s a global commodity, and its value shifts by the split second based on international markets, economic news, and geopolitical events. The ‘spot price’ of gold, which is the benchmark for all transactions, is constantly updating.

What this means for you is that the price you see online right now might be different in five minutes, let alone tomorrow. To secure the best possible value for your gold, you need to act on the live, real-time market rate. We display our live per-gram prices clearly, linked directly to the global index, so you always know you’re getting a fair and current offer.

This isn’t about pressure; it’s about being informed. If you want to lock in today’s per-gram spot rate, visiting us for an immediate, real-time valuation is the only way. The market waits for no one, and neither should your gold sale.

Practical Tips to Protect Yourself When Selling Gold in 2026

Now you know the basics, here are some actionable tips to ensure you get the best deal for your gold, whether you sell to us or anyone else:

• Always Ask for the Per-Gram Price: Don’t settle for a lump sum offer. Insist on knowing the price per gram for each specific caratage (e.g., £X per gram for 9K, £Y per gram for 18K). This allows you to compare offers accurately.
• Confirm They Use Troy Ounces: If they talk about ounces, clarify immediately if they mean troy ounces (31.1035g) or standard ounces (28.35g). If they use standard ounces for gold, walk away.
• Verify Purity Testing: Watch how they test your gold. A reputable dealer will be transparent about their methods and show you the results.
• Check the Live Spot Price: Before you leave home, do a quick search for the current ‘gold spot price’ (usually quoted per troy ounce). This gives you a benchmark to compare against their offer. Remember, dealers need to make a small margin, but their per-gram price should be clearly related to the live spot rate.
• Read Reviews and Ask Locals: In Hull, word travels fast. Ask around, check online reviews. A good reputation for honesty and fairness is invaluable.
• Get Multiple Quotes (If You Have Time): If you’re not in a hurry, getting a couple of quotes can help you gauge the market. Just remember, the market price can shift between quotes.
