Choosing the Right Metal for Your Ring
The metal of your half eternity ring does far more than set the colour — it determines durability, maintenance requirements, hypoallergenic properties, and long-term value. Platinum and gold are the two dominant choices, but they behave very differently over time. Here's what you need to know.
Platinum: The Essentials
Platinum is a naturally white, dense metal with a purity of 95% in most jewelry (marked as Pt950). It's heavier than gold and naturally hypoallergenic, making it an excellent choice for those with sensitive skin.
Pros
- Durability: Platinum doesn't lose metal when scratched — it displaces, developing a natural satin patina called a "patina of wear." Many wearers love this evolved look.
- Stone security: Its density and strength makes it excellent for holding stones securely over decades.
- Hypoallergenic: Suitable for nearly all skin types, including those allergic to nickel.
- Colour permanence: Never needs rhodium plating to maintain its white appearance.
Cons
- Price: Platinum is more expensive per gram than gold, and its greater density means a ring uses more metal by weight.
- Patina: If you prefer a mirror-bright finish always, platinum will require more frequent polishing.
Gold: The Essentials
Gold jewelry is alloyed with other metals to increase hardness, since pure gold (24k) is too soft for everyday wear. The most common purities for fine jewelry are 18k (75% gold) and 14k (58.5% gold).
White Gold
White gold is yellow gold alloyed with metals such as palladium or nickel, then plated with rhodium for a bright white finish. Over time, the rhodium plating wears away, revealing a slightly warm or yellowish tint. Re-plating every one to two years restores the finish.
Yellow Gold
The most traditional metal, yellow gold pairs beautifully with warm-toned gemstones and vintage aesthetics. 18k yellow gold offers a rich colour; 14k is slightly more durable for active wearers.
Rose Gold
A blend of gold and copper alloy, rose gold has a romantic warm tone. It's very durable due to the strength of copper. However, it's not suitable for those with copper allergies.

|---|---|---|---|
| Colour maintenance | Natural — no plating needed | Requires rhodium re-plating | Stable — no plating needed |
| Durability | Excellent | Very good | Good |
| Hypoallergenic | Yes | Often (check nickel content) | Generally yes |
| Weight | Heavy | Medium | Medium |
| Price | Highest | Mid-range | Mid-range |
| Resale value | High | Good | Good |
Which Metal Is Right for Your Half Eternity Ring?
Choose Platinum If:
- You have sensitive skin or known metal allergies
- You want a "buy it once" ring with minimal maintenance
- You prefer a softer, satin-like finish that evolves over time
- You're setting the ring with high-value diamonds and want maximum stone security
Choose Gold If:
- Budget is a key consideration
- You want a warm yellow or rose tone
- You prefer a lighter ring on the hand
- You don't mind occasional rhodium replating for white gold
The Bottom Line
Both platinum and gold are excellent choices for half eternity rings — the decision comes down to personal preferences around colour, maintenance, and budget. Platinum offers superior longevity with minimal upkeep; white gold offers a similar look at a lower entry price. Neither choice is wrong; both can last a lifetime with proper care.
