Sapphire — 5mm SPC Waterproof Flooring (GemCore Flooring)
Sapphire is a wide-format 5mm stone-composite SPC line, built on a 9″ × 72″/72.5″ board with a 20-mil wear layer under a Quartz Enhanced UV Coating and a pre-attached 1mm IXPE pad. It clicks together as a floating floor. The 6-color range runs light-to-medium beige and brown, with one rustic multi-tone shade. Sapphire is FloorScore certified and carries a warranty up to Lifetime Residential. Order any Sapphire color through our Santa Clara showroom.

Colors in the Sapphire collection
Sapphire’s 6 colors stay in a warm beige and brown palette — Anderson, Parkway, and Riverton lean lighter, Madison and Quinn run a shade deeper, and Mitchell is the collection’s rustic multi-tone brown for a room that wants more variation.
Best uses for Sapphire
- Wide open-concept rooms — the 9″-wide, 72″-long board shows fewer seams across a large room than a narrower plank.
- Kitchens & baths — the waterproof stone-composite core and pre-attached pad handle spills without extra underlayment.
- Busy households with kids or pets — a dry-sweep-and-damp-mop routine keeps grit from abrading the wear layer.
- Basements & below-grade rooms — the stone-composite core resists the humidity swings that affect solid wood; follow the install guide’s moisture-barrier requirement.
- Rental turnovers — the floating click install goes down without glue or long cure times between tenants.
Choosing a color from the Sapphire collection
Anderson, Parkway, and Riverton’s lighter beige tones open up a room with limited natural light, while Madison and Quinn’s deeper brown carries well in a sunlit space without washing out. Mitchell’s rustic multi-tone pattern is a good fit for a busy room where hiding everyday wear matters more than a uniform look. Order a sample or visit our Santa Clara showroom to check the color under your own lighting before ordering full cartons — dye lots can shift slightly between production runs.
