All that glimmers doesn’t have to be gold to create a classic glimmering surface. Mica, pearl and seashell are rich alternatives that play with light while they evoke a calming organic mood. Ideal for spas or any sanctuary-like space, these natural materials are extremely luxurious and understated. The soft glimmer of the materials adds visual interest while most remain neutral in color. Unique products, such as a sandstone tile treated with metallic foil and a jaw-dropping stone slab with dichroic inclusions, offer other alternatives to achieve a subtle play of light.
