14K gold, 18K gold or platinum?
Segal makes most designs in yellow, white and rose gold, in 14K or 18K, and in platinum. Here's what those choices change day to day.
| 14K gold | 18K gold | Platinum | |
|---|---|---|---|
| Pure metal content | 58.5% gold | 75% gold | About 95% platinum |
| Scratch resistance | Best of the golds | Softer | Scratches, but metal moves rather than wears away |
| Colour | Lighter yellow | Richer, deeper yellow | Naturally white, grey patina over time |
| Weight | Light | Slightly heavier | Much heavier, feels substantial |
| Relative price | Lowest | Higher | Highest |
What karat really changes
Karat is the share of pure gold. More gold means a richer colour but a softer metal. 14K is harder and cheaper, which is why it's the most common choice in the US. 18K looks warmer, especially in yellow gold, and suits someone who is gentle with their hands.
Yellow, white or rose
The colour comes from the other metals in the alloy. Yellow is classic and makes warm-toned stones glow. White makes white diamonds look whiter but needs re-plating. Rose gets its colour from copper, suits warm skin tones and romantic designs, and is slightly harder than yellow.
When platinum is worth it
Platinum is dense, naturally white and very secure for holding stones. When it scratches, the metal is displaced rather than lost, so prongs last longer. It costs more and feels heavier. It's worth it for a large or valuable centre stone, or for sensitive skin. For most rings, 14K gold is the sensible default.

Questions people ask
Why does white gold turn yellowish?
White gold is gold alloyed with white metals and usually plated with rhodium for a bright white finish. The plating wears over time and needs renewing every year or two. Platinum is naturally white and needs no plating.
Is 18K gold too soft for an engagement ring?
It is softer than 14K and scratches more easily, but plenty of people wear it daily. If you work with your hands, 14K is the practical choice.
Which metal is best for sensitive skin?
Platinum is the most hypoallergenic. Segal also advertises nickel-free gold, which removes the most common cause of reactions to white gold.
