* Beauty: Refers to the quality of being aesthetically pleasing or appealing to the senses.
* Rich: In this context, "rich" doesn't necessarily mean wealthy in money. Instead, it intensifies the degree of beauty. It suggests the beauty is abundant, intense, or full of qualities that make it exceptionally beautiful.
* Rare: Means not common or frequently encountered. It implies that the beauty being described is unusual and special.
So, when something is described as "beauty rich and rare," it is being praised as being exceptionally beautiful and also unique or precious because such beauty is not often found.
