Buying Guide: Trillion Cut Side Stones
- Stone type matters: Moissanite often delivers more fire than diamonds for the same carat weight, while cubic zirconia provides a cost-effective, sparkly alternative. Know which suits your budget and desired sparkle.
- Cut quality: Trillion cuts emphasize triangles and sharp edges. Look for precise symmetry and uniform facets for maximum brilliance, especially in loose stones or settings.
- Center vs. side stones: Decide if trillion sides are the focal highlight or if a larger center stone will drive the overall look. Side stones should complement the center without overpowering it.
- Metal and finish: Two-tone or rhodium-plated finishes can influence perceived color and wear. Hypoallergenic materials help prevent irritation for sensitive wearers.
- Durability and care: Moissanite and CZ offer different hardness and care requirements. Consider wear patterns, cleaning needs, and potential maintenance for longevity.
- Intended use: For engagements, prioritize ring stability and security of side stones. For DIY projects, ensure the stones’ sizes match your planned settings and mounting.
