Gold is not just a metal; it is a measure of meaning. At PureJewels, we honour both craftsmanship and culture, and understanding gold purity is a key part of choosing jewellery that reflects your values and story.
One of the lesser-known but fascinating purities is 900 gold. So what does it mean? And how does it compare to other carats?
What Does 900 Gold Mean?
900 gold refers to a gold alloy that is 90% pure gold, with the remaining 10% made up of alloying metals such as copper or silver. This equates to 21.6 carat gold, sitting just below 22ct (916) gold in purity.
The hallmark “900” is less commonly seen in the UK but is used in various parts of the world, including parts of the Middle East, Southeast Asia, and South America, particularly in older or traditional jewellery.
Is 900 Gold Real?
Yes, 900 gold is very much real and highly valuable. With 90% gold content, it has a rich yellow hue, slightly paler than 22ct (916) gold, and offers a balance of luxury and strength.
While not commonly hallmarked in the UK, it may still appear in imported or bespoke jewellery pieces, especially from heritage-rich regions where high-purity gold is preferred.
Key Features of 900 (21.6ct) Gold
- Gold Purity: 90%
- Carat Equivalent: 21.6ct
- Tone: Deep, warm yellow – similar to 22ct gold
- Durability: Slightly more durable than 22ct due to slightly higher alloy content
- Common Use: High-value gold jewellery, traditional or cultural designs
900 vs 916 vs 750 Gold – A Comparison
| Gold Type | Purity | Carat | Colour Depth | Durability | Typical Use |
|---|---|---|---|---|---|
| 900 | 90% | 21.6ct | Rich yellow | Moderate-High | Heritage/cultural pieces |
| 916 | 91.6% | 22ct | Deeper yellow | Moderate | Bridal, ceremonial jewellery |
| 750 | 75% | 18ct | Elegant warm tone | High | Engagement rings, fine jewellery |
At PureJewels, we specialise in 22ct (916) and 18ct (750) gold — chosen for their excellence, cultural resonance, and hallmark-backed authenticity.
Is 900 Gold Good Quality?
Absolutely. With a purity of 90%, 900 gold is considered high-quality gold. It combines much of the opulence of 22ct gold with slightly improved resistance to scratching or bending. However, it is not typically used for jewellery settings that involve diamonds or complex stonework, where 18ct is preferred for strength.
Should You Choose 900 Gold?
Choose 900 gold if you:
- Appreciate the warm, traditional look of high-purity gold
- Want a piece with substantial intrinsic value
- Are interested in heritage jewellery from regions like the Middle East, India, or Southeast Asia
Choose 750 (18ct) gold if you:
- Prefer a modern finish or diamond-studded design
- Want a piece that’s more resistant to wear
- Seek versatility and strength in everyday luxury
Final Thoughts: 900 Gold in Perspective
Though not commonly hallmarked in the UK, 900 gold carries global significance. It reflects heritage, refinement, and tradition, ideal for jewellery that tells a story across generations.
At PureJewels, we celebrate every shade of gold, curating pieces in 22ct and 18ct that honour both aesthetics and authenticity. Whether you’re investing in a family heirloom or beginning a new chapter, we invite you to explore gold that speaks with meaning.
