However, you could use a descriptive phrase to convey the meaning, such as:
* Jiwe la jade (literally "stone of jade")
* Lulu ya jade (literally "pearl of jade")
These phrases are more literal translations and might not be commonly used. You could also use a Swahili word for a similar stone, like zumaradi (emerald), if the context allows it.
Ultimately, the best way to express "jade" in Swahili would depend on the specific situation and the desired level of formality.
