Obi Stones by Alvaro Coronado, jewelry designer
Obi Stones are easily inserted into your Obi Ring and Obi Pendant thanks to an ingenious martial arts jewelry design by Shotokan martial artist and jewelry designer, Alvaro Coronado. The brilliance of Obi Stones shouts with celebration of your hard work and dedication. The beauty and rich colors of the Obi Stones will tell your story. Each color is deeply rooted in martial arts meaning, indicated in the Obi Stones chart below. Like karate, judo, and all martial arts, the Obi Stones are rich in history and tied to geographic regions of the world and are more clearly defined on our Generation Keepsake Stones chart.

Obi is Japanese for the belt on a karate uniform known as a Gi. Whether student or master, your obi (belt) color signifies your rank and skill level. Through the provisionally-patented jewelry design of Alvaro Coronado, you can now start creating the same significance in a beautifully crafted martial arts piece of jewelry, clearly admired by others, but more importantly, worn with pride and honor. Start by hand-picking Obi Stones from the order chart below to equal that of your belt rank and easily insert in an Obi Ring or Pendant. The Obi stones come in an array of colors and fit both the Coronado’s Obi Ring and Coronado’s Unisex Obi Pendant. The possibilities and combinations are endless since the power of interchanging Obi Stones is yours.

Obi Stones are offered in a variety of gemstones and quality. No matter what your budget, Alvaro Coronado has made it possible to begin creating your Obi Ring or Obi Pendant. Choose from an imitation birthstone or a diamond. True to your art, with time and discipline, you can grow into the semi-precious and precious Obi Stones. All Obi Stones are worthy of honoring your achievement and marking your progress from white belt to black belt and beyond.
