TOPFUND Crystal Singing Bowl Review

Overview

TOPFUND makes frosted quartz crystal singing bowls — the translucent white kind — in sizes from 6 inches up to large practitioner bowls, sold individually by size and musical note (C through B, each labelled with its associated chakra) and in sets. Many are offered in both 432Hz and 440Hz tunings. TOPFUND says its bowls are made from pure quartz, fired at very high temperatures until they fuse into quartz glass.

On Amazon UK, the single bowls listed are mostly 6–10 inches, sold with a heavy-duty carrying case, a cowhide suede striker, and a silicone O-ring to sit the bowl on; some listings add a rubber mallet as well. This is an accessible way into sound cleansing rather than a sound-bath practitioner’s primary instrument — and for cleansing crystals, that’s the right place to start.

Tone and Sustain

Crystal bowls are known for a clear fundamental tone that sustains for a long time before fading — long enough to strike, let it ring out fully, and repeat two or three times without the session feeling rushed. That sustain is the part that matters for cleansing crystals with sound: the technique depends on letting the tone ring to silence between strikes.

Where crystal bowls are more modest is harmonic complexity. A metal Tibetan singing bowl produces several overtones on top of the fundamental, which is what gives it a rich, layered quality; a quartz bowl’s tone is cleaner and simpler by comparison — closer to a single note than a chord. If you’re after the acoustic experience for its own sake, that’s worth knowing. If you’re cleansing a shelf of crystals in the time it takes to make tea, it’s not a meaningful loss.

Choosing a Size and Note

For cleansing a small cluster of tumbled stones at home, the 6–10 inch bowls are the practical range. Smaller bowls sound higher and more focused; larger ones sound deeper and fill more of a room, and cost and weigh more.

Each bowl is sold by note, so you can choose one matched to a particular chakra if that’s part of your practice. For cleansing itself, the specific note matters less than letting the tone ring fully — choose the one that sounds right to you. Whether you pick 432Hz or 440Hz is likewise a matter of preference.

You don’t need to put crystals inside the bowl for it to work — the sound travels through the air regardless — but small tumbled pieces can sit inside if you want to concentrate the tone that way.

Handle With Care

The one thing to take seriously is fragility. A quartz crystal bowl is fused quartz glass, not metal, and TOPFUND’s own guidance is to handle it with the utmost care. Keep it on its O-ring, store it in its case, don’t strike it hard, and don’t let crystals knock against the rim. TOPFUND also advises playing a bowl at least ten inches from anyone’s head.

The Verdict

For sound-based crystal cleansing, the TOPFUND bowl gives you a properly tuned note and everything you need to start in one box, without paying for harmonic complexity you don’t need. Pair it with the selenite charging plate for the two-part cleanse-then-charge rhythm, and you have a complete, low-fuss crystal care setup.

Correction, October 2026: an earlier version of this page described three months of testing, said the bowl came without tuning information, and recommended buying a suede mallet separately. TOPFUND bowls are sold tuned to a named note with a suede striker included. See how we review.
