Ok, depending on what you’re tile looks like I might be able to help. I’m Kingston.
As long as you’re not in a screaming rush, I should be able to find some time to come by, probably have to be a weekend tho.

Here are some photos - the sheen is not too clear as it needs to catch the light but hopefully theres an idea on the last two photos.

Its only about 5cm long but is more apparent than the photos may show.

Its also right in the middle of the floor which is very annoying!
