The Solemn Sapphires are unique gems. Any Hedgehog affected by the Chaos Emeralds or any powerful gem can be affected by the Solemn Sapphires. However their full power is used on both Ice and Water Elementals. It allows them to transform into a new transformation. The Solemn Sapphires can be used with the Chaos Emeralds, Master Emerald, Doomsday Diamonds and/or Gems of Sorrow enabling the being to turn into a very powerful form. The gems it powers up a being with depends on the form the being turns into. But using all of them together will make a very powerful form, but it is very hard to turn into due to the fact that it is very difficult to collect all the gems at once.
