Final answer:
The company's claims in the advertisement are likely to be pseudoscientific and not useful.
Step-by-step explanation:
The claims made by the company in the advertisement are likely to be pseudoscientific and not particularly useful. The statement that ions in their jewelry can balance energy and improve health lacks empirical evidence and scientific plausibility. The claim that nine out of ten people report significant improvement in how they feel is also not supported by sound evidence. It is important to critically evaluate such claims and rely on scientific evidence when considering health-related products.
