Quick answer: Your metal choice comes down to color, durability and upkeep. 14K gold (58.5% pure) is harder, more scratch-resistant and more affordable — the everyday workhorse. 18K gold (75% pure) is richer and warmer — the fine-jewelry standard, slightly softer. Platinum (~95% pure) is the densest, most durable and naturally white metal — no plating, ever — and the most expensive. White gold gives platinum's look for less but needs occasional rhodium re-plating. And whatever you choose at DelaFuente, it's solid gold or platinum — never plated over another metal.
14K vs. 18K gold vs. platinum — which should I choose?
The honest comparison:
| Metal | Purity | Character | Best for |
|---|---|---|---|
| 14K gold | 58.5% gold | Harder, more scratch-resistant, more affordable | Excellent everyday wear |
| 18K gold | 75% gold | Richer, warmer color; the fine-jewelry standard; slightly softer | A traditional, luxurious look |
| Platinum | ~95% pure | Densest and most durable; naturally white; hypoallergenic; most expensive | Maximum security and a forever-white metal |
There is no "best" — there's the best for your hands and your life. Hands-on job or gym life? 14K forgives more. Want the classic warmth of fine jewelry? 18K. Want to never think about plating and hold the stone in the most secure metal? Platinum.
Why isn't jewelry made of pure gold?
Pure gold — 24K — is too soft for daily jewelry: a 24K band would scratch, dent and lose stones within months. So jewelers alloy it: blending gold with harder metals for strength, which is exactly what the karat number tracks (18K = 75% gold, 14K = 58.5%).
The alloy also sets the colour. Yellow gold keeps gold's natural warmth; white gold swaps in white metals like palladium or nickel, then wears a bright rhodium plating for its mirror finish; rose gold owes its blush to a higher dose of copper, which also happens to make it the most durable of the three golds. Same gold, different recipes.
Solid gold vs. gold-plated vs. vermeil — what's the difference?
This is the question that protects your money, so here's the straight version:
- Solid gold — the metal is gold alloy all the way through. It can be polished, resized and repaired forever; it never "wears through."
- Gold vermeil — a thicker layer of gold over sterling silver. Better than plated, still a coating: it wears off with years of friction and can't be meaningfully repaired.
- Gold-plated / "gold-tone" — a microscopic film of gold over brass or steel. It wears through in months, can't be fixed, and often triggers skin reactions as the base metal emerges.
A piece meant for daily wear over decades — an engagement ring above all — should be solid metal, full stop. It's why everything DelaFuente makes is solid gold or platinum, never plated: a coating is a countdown, and we don't build heirlooms on countdowns.
White gold vs. platinum — which is better?
The look is nearly identical on day one; the difference is how they live:
- White gold costs less, weighs less, and wears its bright white as a rhodium finish that needs renewing every couple of years. Alloyed with nickel in some recipes (ask — ours can be nickel-free).
- Platinum is naturally white forever — no plating, nothing to renew. It's denser (you feel the difference), hypoallergenic, and when scratched it displaces metal rather than losing it, so prongs stay secure for decades. It costs more upfront and less in upkeep.
Budget-first: white gold. Forever-first: platinum. Both are honest choices when you know what you're choosing.
Does platinum scratch? (and what is patina?)
Yes — platinum scratches visibly faster than people expect, and that's not a flaw in your ring; it's the metal's nature. Here's the part that matters: when platinum scratches, the metal is pushed aside, not shaved off — over years the surface develops a soft, matte glow the trade calls patina, while the ring loses essentially none of its mass. Many people grow to love the patina (it reads as lived-in elegance); if you don't, a quick professional polish restores the mirror finish any time. Gold, by contrast, actually sheds a little metal with every scratch.
Why is my white gold ring turning yellow?
Because white gold isn't naturally bright white — it's a gold alloy finished with a thin plating of rhodium, and that plating slowly wears with friction and daily life. What you're seeing "turn yellow" is the warmer alloy beneath showing through. It's cosmetic, not damage: a jeweler re-plates it in about a day, inexpensively, typically every one to three years. (Chlorine and harsh chemicals speed the wear — one more reason rings come off for pools and cleaning.) If you'd rather never think about it, that's platinum's quiet argument.
Which metal is safe for sensitive skin or a nickel allergy?
Nickel — used in some white gold alloys — is the most common cause of jewelry skin reactions. If you've ever had a rash from costume jewelry, the safe choices are platinum (about 95% pure and naturally hypoallergenic), palladium-based white gold (nickel-free), or yellow and rose gold in higher karats. Tell us before we cast and we'll build your piece nickel-free — it costs little to nothing extra.
Why is my ring turning my finger green?
It almost never means "fake." The usual culprit is copper — present in most gold alloys, especially rose gold and lower karats — reacting with sweat, lotions or soap residue to leave a harmless greenish mark, easily washed off. Some skin chemistries react more than others, and humid days make it likelier. If it bothers you: higher karat gold, platinum, or a professional clean of the ring (built-up residue is often the real offender). Persistent irritation — as opposed to a colour mark — is more likely a nickel allergy, solved with nickel-free metals.
Which gold color should I choose — yellow, white or rose?
Taste first, always — but a few honest guides:
- Yellow gold flatters warm and olive skin tones, makes white diamonds pop by contrast, and forgives lower colour grades (a G–H diamond reads whiter against yellow). The most traditional, and back in full fashion.
- White gold / platinum reads modern and cool, disappears behind the stone (all eyes on the diamond), and keeps blue and pink stones true to their colour.
- Rose gold is the romantic: warm on every skin tone, beautiful with morganite and champagne diamonds, and the most durable gold alloy thanks to its copper.
And the quiet rule: match the metal to the life, not just the look — the prongs holding your stone care more about metal choice than the Instagram photo does.
