The 18kge marking on rings means the piece is made of 18-karat gold (75% pure gold) mixed with other metals (25%) for added strength and durability. The "ge" typically indicates the manufacturer or country of origin.
Hallmarks are small stamps on jewelry that indicate metal composition, manufacturer, and sometimes country of origin. For gold, the karat number shows purity level (24k being pure gold). The letter or letters after the number often identify the manufacturer or assay office.
| Marking | Meaning | Gold content |
|---|---|---|
| 18k | 18-karat gold | 75% |
| 18kge | 18-karat gold with manufacturer mark "ge" | 75% |
| 14k | 14-karat gold | 58.3% |
| 925 | Sterling silver (92.5% pure silver) | 92.5% |
Pure gold (24k) is too soft for everyday wear. Mixing it with other metals creates an alloy that's more durable while maintaining gold's appearance. The 18kge marking specifically indicates this balance between purity and strength.
For example, an 18kge wedding band would contain 75% gold and 25% other metals like copper or zinc, making it suitable for daily wear while retaining the look of gold.
Many people confuse the manufacturer mark ("ge" in this case) with a purity indicator. Unlike the karat number, which shows gold content, the letters after usually identify the maker or assay office.
Another misunderstanding is assuming all rings with similar markings come from the same place. The "ge" mark could represent different manufacturers in different countries, though it often traces back to German or European origins.
When researching what does wearing a black ring mean, you might encounter various interpretations, but understanding the physical markings on rings provides a concrete starting point for authentication and valuation.
I once helped a client authenticate a vintage ring by researching its hallmarks. The 18kge marking led us to identify it as likely European, dating from the early 20th century - a detail that increased its value.
