步驟 1: Plan the facets

Wash and dry your rock. Using a pencil, divide the surface into geometric facets — triangles and irregular polygons that look like the flat surfaces of a cut gemstone. Draw lines from a central point outward for a realistic crystal structure.

步驟 2: Paint the base shades

Fill each facet with a different shade of purple, blue, or lavender. Facets that would catch light should be lighter colors, while those in shadow should be darker. This creates the illusion of a three-dimensional gem.

步驟 3: Define the edges

Using your fine detail brush and white paint, carefully trace along the pencil lines where facets meet. These white lines represent the sharp edges where light catches on a real crystal. Keep lines straight and crisp.

步驟 4: Add light reflections

On the lightest facets, add a bright white highlight — a small, elongated shape that represents the light source reflection. Add subtle white or light blue streaks on adjacent facets to show light scattering through the crystal.

步驟 5: Add depth shadows and seal

Deepen the darkest facets with a touch of dark purple or black along their edges. Add a subtle shadow beneath the crystal at the rock base using dark paint. Once fully dry, apply clear sealant for a glossy, gem-like finish.

步驟 6: Final touches

Review your gem for color balance. Adjust any facets that need more contrast. Add tiny sparkle dots with white paint near the brightest highlight. Apply a second coat of sealant for extra shine that mimics a polished gemstone.

步驟 7: 添加 RoxGeo 代碼

在你的石頭底部或背面寫上 ROXGEO.COM,接著加上斜線和你石頭的唯一代碼(例如 ROXGEO.COM/ABC123)。這樣尋找者就能直接訪問你石頭的個人資料頁面並記錄他們的發現。如果石頭太小無法寫下完整地址,可以寫 #ROX,接著是沒有空格的代碼(例如 #ROXABC123)——這樣簡短,容易在 Google 上搜尋,並直接引導到你石頭的旅程頁面。使用細尖的永久性標記筆或壓克力畫筆,並用透明清漆封住,這樣代碼在雨水、陽光和冒險中都能保持可讀。
