Create a realistic image of a humanoid character with a muscular build and skin that resembles blue diamond, reflecting light with a crystalline texture. The character should have black and gold accents on the shoulders and waist, resembling armor or clothing. The face is angular, green like tinted glass, with sharp, defined features that give it a stern expression. The jaw is segmented, suggesting it's also made of a crystalline structure. Include black boots and a harness across the torso, which adds to the character's heroic stature.
