30" Natural Stone Sphere Fountain Kit
A commanding 30-inch solid stone sphere, smoothed by the hands of artists, with water bubbling from the top and sheeting over every curve. Choose black granite, crystal-swirled black flower granite, or golden yellow onyx.
At 30 inches across and well over half a ton, this is Blue Thumb's statement sphere. Water rises through the drilled center, bubbles from the crown, and glides evenly over the polished stone before disappearing into the buried basin beneath a bed of pebbles. Its "transitional" styling suits contemporary and traditional landscapes alike.
Black Granite offers a deep, uniform black. Black Flower Granite has a marbled look, with crystal swirling through the black stone. Yellow Onyx shows golden, amber, cream, and honey tones with a striking natural translucency. Each sphere is cut from natural stone, so color and pattern vary from piece to piece.
Genuine granite or onyx, polished to showcase the stone's character.
A large-scale focal point for estates, entries, and commercial landscapes.
Keeps the basin topped off when connected to irrigation or a supply line.
MuckBuster® and Algae D-Solve® help keep the water clear from day one.
Water recirculates from a hidden basin — no open pond to maintain.

Will my sphere look exactly like the photos?
These are natural stones, so color, veining, and pattern vary from piece to piece. Call us if you'd like help with stone selection.
How is a sphere this heavy delivered and installed?
At 1,250–1,450 lbs, the sphere ships by freight and requires equipment to place. Plan site access before ordering, and call us for a freight quote.
Do I need a pond?
No. The sphere sits over a buried 52" Altum basin that stores and recirculates the water, hidden under the included pebbles.
Can I add lighting?
Yes. Fountain spotlights make a dramatic nighttime upgrade. Lighting is not included in the kit.
What about winter?
In freezing climates, remove the pump and drain exposed plumbing before a hard freeze. Call us and we'll help you plan for your climate.
