Slab Yard Diagnostic Protocol
Quartzite is widely mislabeled in the trade — slabs sold as quartzite are sometimes dolomitic marble (e.g., Super White) or hybrid marble/quartzite layers (e.g., Fantasy Brown). Before you commit, run two quick tests from your Stone ID Kit to confirm the slab is genuine quartzite.

Potential Translucency
Some slabs of this quartzite may exhibit natural translucency and can be backlit for dramatic effect. Verify translucency on your specific slab before planning a backlit installation.

Resin Fill — UV Yellowing Risk
Cristallo Gold is typically filled with polyester resin during processing to stabilize micro-fractures and enhance appearance. This resin can yellow over time when exposed to direct sunlight or UV light. This yellowing is irreversible and most noticeable on white, light-colored, and blue stones. For areas with direct sun exposure (near windows, outdoor kitchens, sunrooms), discuss UV-stable epoxy resin options with your fabricator, or consider placement away from prolonged direct sunlight. Ask your supplier whether the slab uses polyester or UV-stable epoxy resin.

Care Instructions
Maintenance recommendations for Cristallo Gold
🧹 Daily Cleaning
- Wipe surfaces with a soft, damp cloth or microfiber towel
- Use a pH-neutral stone cleaner — never use acidic or abrasive products
💧 Sealing Schedule
- Sealer type: Yes (impregnator)
- Seal every 1–2 years for normal residential use
- Test with water drops — if absorption occurs within 10 minutes, it's time to reseal
- Always clean the surface thoroughly before applying sealer
- Allow sealer to cure fully before using the surface (typically 24 hours)
⚠️ Warning Signs — Time to Call a Pro
- Dull spots or rings where liquids have sat on the surface
- Visible cracks, chips, or separating seams
- Discoloration or staining that won't clean away
- Surface feels rough or gritty in areas that were previously smooth
- Grout deterioration around the stone edges
