Which Jewellery Does Not Lose Value? ## 11 November 2024 **[18-carat Gold and Tahitian Pearl](https://www.poemotu.com/perles-de-tahiti/fr/): A Sustainable Investment** In the jewellery world, not all [**jewels**](https://www.poemotu.com/perles-de-tahiti/fr/) are equal in terms of value over time. Some lose their luster or appeal, while others, due to the rarity of the materials and the quality of craftsmanship, retain or even increase their value. So, **which jewel does not lose value?** At [**Poemotu**](https://www.poemotu.com/perles-de-tahiti/fr/), we believe the combination of **18-carat gold** (750/000) and **Tahitian pearl** embodies the perfect answer to this question.

But why this particular alloy? In jewellery, gold comes in different carats, indicating the percentage of pure gold in the alloy. - **24 carats** **(99.9% pure gold)**: Pure gold is too malleable for most jewels worn daily. Although it retains its intrinsic value, it is rarely used in jewellery due to its fragility. - **18 carats (75% pure gold)**: 18-carat gold, or 750/000 by European standards, is one of the most coveted alloys for [**high-end jewellery**](https://www.poemotu.com/perles-de-tahiti/fr/).

Choosing **18-carat gold** is opting for a precious, durable, and resistant material, suitable for jewels passed down through generations.
