Buying Guide
What should you consider when choosing crystal or acrylic engraving blocks?
- Material: K9 crystal provides superior clarity and depth for inner engraving, while acrylic offers lightweight, budget-friendly options with a floating-display effect.
- Engraving method: Inner laser engraving is ideal for high-detail 3D designs; surface engraving works with both K9 and acrylic blocks but differs in depth and finish.
- Size selection: Smaller cubes are excellent for intricate motifs; larger blocks support portraits and multi-element designs.
- Display and gift context: For keepsakes, consider block sets that can be grouped or displayed together; for awards, opt for uniform sizes with clear edge quality.
- Quantity and plan: Bulk packs reduce per-block cost but require storage and consistent engraving setup.
