Jewel Sword
From Castlevania: Symphony of the Night Wiki
When you kill an enemy with the Jewel Sword, there is a chance for the Jewel Sword to spawn a random Gem. If a Gem is spawned, the ratio of which Gems will spawn is as follows:
Item | Ratio
+------
Zircon | 3073 Aquamarine | 768 Turquoise | 208 Onyx | 32 Garnet | 8 Opal | 5 Diamond | 2
The Jewel Sword also has a special attack that spawns a random number (TODO: How many?) of $1 coins you can pick up.
