Valley Gold Vein Marble can be a good choice for stairs, depending on your personal preferences and specific requirements. Here are some factors to consider:

1. Appearance: Valley Gold Vein Marble typically features a beautiful golden or beige color with natural veining patterns. This can add an elegant and luxurious look to your stairs.

2. Durability: Marble is a durable material, but it is softer than some other natural stones like granite. It can be prone to scratches and may require periodic sealing to protect against stains. However, for indoor stairs with normal foot traffic, it should hold up well over time.

3. Slip Resistance: Marble is generally quite smooth, and it can be slippery when wet. To ensure safety, you may need to enhance the slip resistance of the marble stairs by using nonslip mats or installing a textured finish on the surface.

4. Maintenance: Marble needs regular maintenance to keep its appearance. It should be cleaned with mild, pH-neutral cleaners and polished regularly to maintain its shine. It is important to avoid acidic or abrasive cleaners that can damage the marble.

Overall, Valley Gold Vein Marble can be a good option for stairs if you are willing to maintain it properly and address potential safety concerns. Consulting with a professional or marble supplier can help you make an informed decision based on your specific needs and preferences.
