What is 24k gold?
24k gold is the purest form of the precious metal, composed of 99.9% fine gold with no mixing with other metals or alloys.
What are the properties of this precious metal?
Pure gold stands out immediately at first glance due to its solar yellow color, which is very intense and deep, differing significantly from the softer shades of commonly used alloys. It is a noble material that does not oxidize, never tarnishes, and retains its luster, no matter the conditions.
- High density: A pure gold ring will feel particularly heavy in your hand.
- Malleability: Its molecular structure makes it very soft compared to other metals.
- Hypoallergenic: It is free of nickel or copper, so there is no possibility of a skin reaction.
To understand the nuances between gold and its carat, remember that the number 24 represents the top of the purity scale in jewelry.
Why is 24k gold rarely used in Western jewelry?
Although its purity is fascinating, the extreme malleability of 24k gold poses a major technical problem for creating jewelry intended for everyday wear. A ring made entirely of this metal quickly deforms upon contact with hard objects, and the prongs holding precious stones could open with the slightest pressure.
For a more durable piece, such as one of our engagement rings, it is preferable to choose a metal whose hardness has been reinforced. 24k gold is more suitable for investment pieces in the form of ingots or for certain ceremonial jewelry not worn daily.
How does it compare to other carats?
The main difference between alloys lies in the compromise between hardness and purity. While 9k or 10k gold is very hard but contains less than 50% gold, 18k prioritizes the preciousness of the material while remaining robust enough for everyday wear. It is often the metal of choice for custom creations or symbolic pieces such as gold wedding rings. Here's a quick comparison:
- 24k: 100% gold, too soft for jewelry, very intense yellow color.
- 18k: 75% gold, ideal for fine jewelry, optimal balance.
- 14k: 58.5% gold, harder and more affordable, paler yellow color.
- 10k: 41.7% gold, very durable but duller and more brittle.
Frequently Asked Questions about 24K Gold
The safest way is to check the hallmark stamped on the metal, which should indicate "999" or "24K". You can also consult our tips for identifying real gold jewelry using a few simple tricks.
Yes, because pure gold solders very well, but its softness sometimes makes repairs delicate if the structure is too deformed. In our workshop in Montreal, we always assess whether a transformation to a harder alloy would be more appropriate for the longevity of the piece.
Generally yes, because the price of a piece of jewelry depends directly on the quantity of fine gold it contains per gram. However, the complexity of the ring design work and the rarity of the set stones can make an 18k piece of jewelry more expensive than a simple piece made of pure gold.
