I could not say for sure because of the angle and the lighting of the photo i can't see very clearly the detail, but i think it could be a bright ceramic border tile, because they come in many new ways that sometimes surprise us that is true, but you should visit this link: , i think it must be the same material, its good to use it because it reflects the ambiance color, i hope this information helps you

The tiles are a glass mosaic tile. The are 5/8" X 5/8" glass and brushed aluminum. The trim at the top is a 1/2" X 5/8" brushed aluminium to match the accents in the tile.

We carry a few glass mosaic tiles in our 'Glimmer' collection that are similar to this called 'Cloud White" and "Mixed Cloud White" that will give you a look like this one. I would get a few samples and put them in the space to get an idea of how they will look. If we can answer any questions feel free to contact us. We would love to help.
