The vast majority of gold jewelry sold in Senegal is 18 karat — and most people have no idea what it's really worth. The result: they accept an offer at random, without knowing whether it's fair.

What "18 karat" means: 75% pure gold
The karat measures the purity of gold. Pure gold is 24 karat — that is, 99.9% gold. But pure gold is too soft to make sturdy jewelry: it's therefore mixed with other metals (copper, silver, etc.) to form a resistant alloy.
18-karat gold contains 75% pure gold and 25% other metals. That's what the "750" hallmark (for 750‰) indicates, often found inside rings and on chain clasps. To understand how these mixes are composed, read our article on the different types of gold alloys.
For reference, here are the purities of the main karats:
- 24 karat: 99.9% gold (pure gold).
- 21 karat: 87.5% gold.
- 18 karat: 75% gold.
- 14 karat: 58.3% gold.
How to calculate the 18-karat gold price per gram
This is where it all becomes concrete. The buyback value of an 18K piece rests on three elements:
- The exact weight of the piece, weighed to the gram (and to the tenth of a gram) on a precise scale.
- The purity: 75% for 18 karat.
- Today's rate, which sets the value of a gram of pure gold.
The formula is simple: weight × 75% × today's price per gram of pure gold = the value of your 18-karat gold. In other words, a gram of 18K gold is worth three quarters of a gram of pure gold. To get an amount in FCFA — the 18-karat gold price per gram in CFA — you just apply this calculation to the current rate shown on our prices page.
Try it now: take the approximate weight of your ring, multiply it by 75%, then by today's price per gram of pure gold. In a few seconds you'll get a realistic range of what your piece is worth. We never make up a price: everything starts from the world rate of the day, public and verifiable.
Why 18-karat gold is the most common in Senegal
If you're looking for the price per gram of 18-karat gold in Senegal, it's probably because most of the jewelry around you is precisely 18K. That's no accident:
- A good balance. With 75% gold, 18 karat offers a beautiful golden color while staying sturdy enough for everyday use.
- Durability. More durable than 24K (too soft), it's perfect for rings, wedding bands and chains worn every day.
- Value. It keeps a high gold content, and therefore a real resale value.
That's why most wedding bands, engagement rings and everyday jewelry in Senegal are 18 karat.
The mistake to avoid: confusing purchase price and buyback price
Here's mistake number one: believing that the buyback price of your 18K ring matches what you paid for it in the jewelry shop. These are two different things. In the shop, you pay for the gold + the craftsmanship + the brand + the merchant's margin. At resale, only the gold actually contained matters — that is, 75% of the weight, valued at today's rate.
Also be wary of "eyeball" estimates, without a scale, and of any price quoted without taking the karat into account. A serious buyer tests and weighs in front of you, then explains the calculation. To dig deeper, see our guide to selling your 18-karat gold jewelry.
