The Artemis's handle is short, white, and has a pink spike set in its pommel. The guard is grey with a short, light grey protrusion on either of its sides. The main blade has a vague arrowhead-like shape with ridges in its sides. It also has two diamond-shaped gaps in its center. The main blade is mostly gold and the entire blade as black edges. A vertical line also runs down the middle of the main blade.
When Saïx enters his berserker state, the lower section of the Artemis is unchanged, but the main blade is bisected down the middle and the tips of the two new blades slant to opposing sides. The two diamond-shaped gaps now become a thin, gold blade. An additional, white blade with yellow edges connects the two halves of the main blade to this new blade.
Its name refers to the Greek moon goddess, Artemis.
