Are kidney stones dark in color?

I passed a small kidney stone last week, and it was quite dark in color. Is that normal? Are kidney stones usually dark in color, or does it depend on the type?

They can be dark yellow, brown, or even black sometimes. I have thyroid issues so I keep getting regular blood tests and health checkups to make sure all my levels are okay. Please consult a doctor and get an ultrasound done to be sure.

Yes, some of them can be very dark brown or rough-looking. Honestly, please don't wait like I did; I ignored a mild back pain for weeks and suffered so much later. Get a checkup done immediately before the pain gets severe.

I completely understand how scary it is to wonder about these details, I also used to Google everything and panic. But yes, stones can be dark brown, yellow, or even black depending on what they are made of. Please take a deep breath and let a doctor examine you, it will ease your mind.

They sure are, mine was a dark, tiny brownish crystal. Depending on whether they are calcium oxalates or uric acid, the color changes. Just focus on drinking plenty of water and if the doctor gave medicines, take them on time.

Yes beta, they can be dark yellow or muddy brown. I tried many home remedies like drinking plenty of lemon water and coconut water which helped me pass a small one. But remember, if the stone is big, home remedies won't magically melt it, you must see a doctor.
