100% natural ruby & sapphire beads!

Both ruby and sapphire are varieties of corundum, one of the hardest gemstones after diamond, with a Mohs hardness of 9 and notable density that gives these beads a satisfying weight in hand. The strands feature a natural mix of red ruby and blue sapphire, often appearing as purples where the colors meet. Durable, vibrant, and timeless, they bring elegance and substance to any jewelry design.

Ruby is the birthstone of July, and Sapphire is the birthstone of September.

Recommendations

For beads 4mm and smaller, it is recommended to start with stringing wires no larger than .013inch / .33mm. This will ensure a proper fit and in most cases allow for feeding of the wire tip back through the beads for a clean finish.

Elastic cords can be used with beads 4mm and larger, but it will not fit through most beads smaller than 4mm. It's recommended to use 0.5mm elastic cord.

These recommendations are intended to help guide you for a successful project. With time and experience you'll discover what works best for your designs.
