Its first appearance was in Castlevania: Symphony of the Night as a "Fairly Valuable Ring". It could be sold to the Master Librarian for 1,500 Gold, which is more valuable than a Aquamarine (800 G) and less valuable than Onyx (3,000 G). Turquoise is rarely dropped by the Jewel Sword.
Turquoise is also second least valuable Jewel in Castlevania: Lament of Innocence (800 Gold), which is twice as much Zircon, but less than an Opal. Using a Turquoise with the Jewel Crush randomly switches the sub-weapon that you have equipped. You do not have an opportunity to change back to the old sub-weapon. This helps "protect travelers" in that it gives a chance that you may get an item you need when you are far from a place where you could get it.
