The red-hued lightsaber blades generated by such crystals were often nicknamed 'bloodshine blades'. Most synthetic crystals were red, a result of the forging process, and often times the initiate's intentional manipulations, as most individuals who utilized synthetic crystals were Darksiders. Also, their common usage by Sith and other Darksiders after this discovery caused synthetic crystals to become something of a staple among such groups, and their use among Jedi was strongly discouraged.
As a result of their artificial origins, synthetic crystals created more powerful lightsaber blades and could be more easily augmented. Though synthetic crystals were ordinarily unsuitable for use in lightsabers, the Sith discovered that they could create synth-crystals that were energized, magnetized, and modified with the power of the dark side of the Force in special furnaces, causing the crystal to glow in harmonic vibration.
