Ruby

Size: Approx 4mm(+/-0.5mm)
Hole size: Approx 0.6-0.8mm
Color: Pink Red

These are round cut beads of synthetic Ruby. Synthetic Ruby is created by artificially generating the crystal structure of Ruby. It was the first gemstone to be synthesized and has been in demand for a long time. The eye-catching vivid red-pink color is very beautiful. Another charm of these beads is their brilliance. Thanks to high-quality polishing and sharply finished edges, you can see a strong sparkle.
Another size has been appraised, and the result is "Synthetic Ruby".
