Syzygium samarangense (syn. Eugenia javanica) is a species in the Myrtaceae. Common names include wax apple, love apple, bell fruit, jambu air ("water guava" in Malay), water apple and rose apple.
The fruit has a crunchy texture, which is sweet and very juicy, and it has nothing similar to an apple except for its color. The color of its juice is purple. The fruit's pith is like cotton. To eat, the core is removed and the fruit is served uncut, in order to preserve the unique bell shape presentation.
In South East Asia, the black ones are nicknamed "Black Pearl" or "Black Diamond," while the very pale greenish white ones are called "Pearl." They are among the highest priced ones in fruit markets.
