Rupee Shard

For The Legend of Zelda: A Link to the Past & Four Swords on the Game Boy Advance (GBA).

In the Chambers of Insight

The yellow Rupees that sometimes appear after you open a chest or defeat an enemy are Rupee Shards. If you collect four of them, they combine to form a giant Rupee worth a total of 500 Rupees.

The game says four shards make a Rupee worth 500, while the Player's Guide says eight.

From the official guide

If you collect eight Rupee Shards, they'll turn into a special gem that is worth 500 Rupees. After a player collects eight, more Rupee Shards will show up in the dungeon.
