The Diamond is generally the most valuable jewel that can be found in the Castlevania games. It is often found embedded in a ring, which is sometimes called the Diamond Ring, and is associated with the Holy attribute, healing and Defense.
Appearances and characteristics
Its first appearance was in Symphony of the Night, where it is referred to as a "Highly Valuable Ring". It could be sold to the Master Librarian for 20,000 Gold, having the highest value of any other jewel ring, being more valuable than an Opal (5,000 G). The Diamond is extremely rarely dropped by the Jewel Sword (if ever).
The Diamond is also the most valuable gem in Harmony of Dissonance. It is worth 1,000 G (which is considerably less in proportion to other gems appearing in other games), which is more valuable than a Ruby (600 G).
The Diamond in Order of Ecclesia is an item that by itself does nothing. It is needed for Laura's "A Heartwarming Accessory" quest. If the player brings Laura a Diamond and an Onyx, she will make available the Diamond Ring (greater Light offensive power), Diamond Pins (greater defense against Light), Onyx Ring, and Onyx Pins at Jacob's shop.
Other Diamond items
Because Diamond is the hardest natural substance known to exist, any piece of equipment that is made of it tends to give more defense than any other of that type of equipment that is not supernaturally enhanced. The Diamond Plate is the most durable non-enchanted armor found in whatever game it is found in. Charlotte Aulin has a "diamond set" that maximizes her Defense. It consists of the Diamond Corset (+32) for the body, Diamond Shoes (+6) for the legs, Diamond Tiara (+10) for the head, and the Diamond Brooch (+5) for the Accessory.
