Raw Ruby (Red Corundum) and Carborundum Ring

A bold two-stone ring pairing raw ruby (Red Corundum), the red variety of corundum, with iridescent carborundum. The ruby keeps its natural granular crystal texture and vivid red tone, while the carborundum brings a darker metallic surface with flashes of blue, violet, green, and steel-like light.

Ruby (Red Corundum) has been treasured for centuries across Asia, the Middle East, and Europe, often admired for its intense color, durability, and association with status and vitality. As red corundum, ruby belongs to the same mineral family as sapphire, with its color caused by trace chromium.

Carborundum, by contrast, has a more modern story. It is the common name for crystalline silicon carbide, a material known for extreme hardness and industrial brilliance. Together, the two create a striking contrast: ancient gemstone energy beside futuristic metallic iridescence.

Ruby (Red Corundum) is often associated with vitality, courage, passion, and inner fire. Its deep red color gives the ring a strong, energizing feeling, often linked with confidence and emotional strength.

Carborundum is commonly connected with protection, resilience, transformation, and bold self-expression. In this ring, ruby brings warmth and intensity, while carborundum adds a darker, sharper, more futuristic edge. The overall feeling is powerful, unconventional, and magnetic — a piece for someone drawn to strength, contrast, and individuality.

Stone: Ruby (Red Corundum), Carborundum

Source: China; Carborundum is typically lab-created silicon carbide

Formation:
Ruby is the red variety of corundum, an aluminium oxide mineral coloured primarily by trace chromium. It forms under high-temperature geological conditions, commonly in metamorphic rocks and some igneous environments. Carborundum is the trade name commonly used for crystalline silicon carbide, a material produced under extremely high heat. Its dark metallic body and rainbow-like surface reflect its crystal structure and the way light interacts with it.

Ring material: Brass with silver-tone finish.
Alternative finishes and sterling silver versions may be available upon request, depending on the design.

Band: Adjustable open band

Size: One size — fits most (approx. US 5–10.5)
