10-14" 2-Note 432Hz Perfect Pitch Perfect Fifth Empyrean Fusion Crystal Singing Bowl Set Crystal Vibes #set684
Two Empyrean Gemstone Fusion bowls chosen to sound a perfect fifth together — a 14" G in ruby and a 10" D in carnelian, both at 432Hz perfect pitch. Each is crafted from 99.99% high-purity quartz sand, hand-polished to a flawless finish that eliminates friction, then infused with finely crushed gemstone through a specialized fusion process. Free from scraping noise and responsive to the lightest touch, they sing with remarkable clarity, sustain, and harmonic depth.

What a Perfect Fifth Is
A perfect fifth is the interval between two notes whose frequencies sit in a 3:2 ratio — the simplest relationship in music after the octave. The G bowl rings at 193 Hz and the D at 289 Hz, landing almost exactly on it. Their overtones line up rather than collide, which is why a fifth sounds open and settled instead of tense. Nothing in it asks to resolve, so the two bowls can ring together for a long stretch under a sound bath, a meditation, or savasana.
The pair also does something neither bowl does alone. Play them together and a low third voice appears beneath both, roughly an octave below the G — created by the way the ear responds to two strong tones at once. It's what makes a well-matched pair feel physically larger than two instruments.
Ruby — 14" G Note
Ruby is a stone of intense energy and life force, infusing the body with vitality and reconnecting you with your zest for life after periods of exhaustion, stagnation, or burnout. Working with it feels like a direct charge from the Earth — grounding yet invigorating, enhancing the flow of chi and leaving you more present and engaged. Sanskrit texts call ruby ratnaraj, king of precious stones; warriors across several cultures embedded rubies beneath the skin before battle for protection and courage. It is associated with the root chakra, and it's the stone in the larger, lower-pitched of these two bowls.
Carnelian — 10" D Note
Carnelian pulses with life force, igniting motivation and driving ambition forward. Its bold orange and red tones reflect its power to awaken the sacral and root chakras — like a cup of spiritual espresso when you feel stagnant or uninspired. It's the stone for taking bold steps and overcoming inertia, replacing procrastination with progress and fueling courage against self-doubt. Carnelian has been worked for over four thousand years: Egyptians called it the setting sun and placed it in tombs for protection, Mesopotamian warriors carried it for courage, and Romans cut it into signet rings because hot wax releases cleanly from its surface.
Why These Two Together
Ruby and carnelian are the two great vitality stones of the lower chakras — ruby at the root, carnelian at the sacral. Ruby supplies the charge; carnelian moves it. Pairing them in the most stable interval in music gives you a set that activates without agitating: the sound stays open and settled while the stones work at the level of drive, courage, and life force.
