How Much Is 18K Gold Worth in Canada?

How Much Is 18K Gold Worth in Canada? (A Simple Pricing Guide)

Gold prices move every day — so instead of giving you a number that changes tomorrow, this guide shows you exactly how to calculate 18K gold value in Canada, the smart way.

We’ll keep it simple, clear, and confidence-building.

1) The 2 Values You Should Know (Retail vs “Gold Value”)

When people ask “How much is 18K gold worth?” they usually mean one of these:

A) Gold Value (Melt Value)
This is the value of the gold content based on weight and purity.

B) Retail Value (Jewellery Price)
This includes gold value plus design, craftsmanship, finishing, brand, and sometimes stones.

Luxury tip: Fine jewellery can be priced above melt value — that’s normal. The key is knowing what portion is gold value and what portion is premium.

2) What “18K” Means (and Why You’ll See “750”)

18K gold is 75% pure gold. You’ll often see it stamped as:

-18K / 18KT / 18ct

-750 (meaning 750 parts per 1000 are gold)

In Canada, the Competition Bureau’s guidance notes they accept 750 as a quality mark for gold (and 925 for silver).

3) The Formula to Calculate 18K Gold Value (in CAD)

Gold spot price is typically quoted per troy ounce, not per gram.

Step 1 — Convert spot price (per troy ounce) to price per gram
A troy ounce = 31.1035 grams.

So:
Price per gram (24K) = Spot price per troy ounce ÷ 31.1035

Step 2 — Adjust for 18K purity
18K is 75% pure, so multiply by 0.75.

So:
18K value per gram = (Spot ÷ 31.1035) × 0.75

Step 3 — Multiply by weight (grams)
Total 18K gold value = 18K value per gram × grams

4) A Realistic Example (Simple)

Let’s say (example only) the 24K spot price is CAD $X per troy ounce.

-24K per gram = X ÷ 31.1035

-18K per gram = (X ÷ 31.1035) × 0.75

-If your item weighs 10g, total gold value = 18K per gram × 10

That’s it — now you can estimate value in seconds.

If you prefer tools, several Canadian gold buyers provide calculators and daily pricing pages you can compare against (helpful for a reality check).

5) Why “What You Get Paid” Can Be Less Than Your Calculation

If you’re selling gold jewellery, many buyers pay a percentage of melt value to cover refining and business costs.

Some Canadian buyers publicly explain their pricing approach (percent of spot or commissions), and you’ll see this vary by business and item type.

Luxury tip: If you ever sell, get 2–3 quotes, and bring any documentation you have.

6) Smart Buying Tips (So Your 18K Purchase Holds Value Better)

If you want your purchase to be both beautiful and value-smart:

-Choose 18K/750 clearly stamped pieces

-Prefer timeless designs (minimal styles age better)

-Heavier, solid construction often retains value better than ultra-hollow pieces

-Keep receipts and product details (useful for insurance/resale)

-Buy from a seller who is transparent about karat and quality marks

Final Thought

Knowing how 18K gold value is calculated gives you real confidence — whether you’re buying, gifting, or comparing prices. And if you’re choosing jewellery for both elegance and long-term meaning, 18K (750) remains one of the strongest, most balanced choices in fine jewellery.
