Materials Needed

Large, flat round rock (at least 10 cm diameter)
Golden yellow and orange acrylic paint
White acrylic paint (for base coat)
Fine detail brush (size 0 or 00)
Medium round brush
Compass or circular stencil
Toothpicks and dotting tools
Pencil (for sketching)
Clear sealant spray

Step-by-Step Instructions

1

Step 1: Prepare and prime the rock

Wash and dry the rock thoroughly. Paint the entire surface with two coats of white acrylic paint, letting each coat dry fully. A smooth, round rock at least 10 cm across gives you the best canvas for intricate mandala detail work.

Step 2: Sketch the mandala grid

Using a compass and pencil, draw a small circle at the center of the rock. Add concentric circles at equal intervals outward. Divide the rock into 8 or 16 equal segments with radiating pencil lines to create your symmetrical mandala grid.

Step 3: Paint the golden base color

Fill the entire top surface with two coats of deep golden yellow paint, working carefully within the pencil guidelines. This warm solar base will make your finished mandala glow with the energy of the sun. Let dry completely before continuing.

Step 4: Paint the inner sun core

Using bright orange paint and a fine brush, paint a bold circle at the very center. Add short radiating flame-like strokes around it to create the burning core. Place a precise bright white dot at the absolute center using a dotting tool dipped in white paint.

Step 5: Build the first ring of petals

Paint symmetrical teardrop-shaped petals around the central core, following your grid lines. Each petal should be evenly spaced and identical in size. Use a medium brush for the body of each petal and your fine brush to refine the pointed tips to a crisp finish.

Step 6: Layer outer rings with geometric detail

Add progressively larger and more elaborate rings outward: chevron bands, triangular points, and small dot clusters between each major petal layer. Check symmetry after each ring by rotating the rock and comparing opposite sections carefully.

7

Step 7: Add stippling and dot-work details

Load a toothpick or fine dotting tool with white or orange paint and add rows of uniformly sized dots along the border of each completed ring. This stippling technique creates beautiful texture and is the hallmark of traditional mandala stone art.

8

Step 8: Outline, refine and seal

Once all paint layers are fully dry, use a fine brush with slightly diluted black or dark brown paint to outline key shapes for clarity and contrast. Apply two coats of clear sealant spray, allowing full drying between coats. Your sun mandala rock is complete.

Step 9: Add RoxGeo Code

On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.

Helpful Tips

Use a compass for perfect circles - freehand circles look less professional in mandala work.
Always work from the center outward, completing each ring fully before starting the next.
A mandala compass dotting tool set makes spacing dots uniformly much easier and faster.
Test your dotting tool pressure on a spare rock before applying to the design.
The painting looks busier than expected in progress - trust the grid and it will come together beautifully.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
