Onyx is a black volcanic gem that is commonly worn in jewelry. The value of onyx is determined by the quality and size of the stone. Onyx stones can sell for tens or hundreds of dollars.
In order to determine how much black onyx is worth, the size of the onyx, overall condition, and purity needs to be determined. However, a small ring with a black onyx piece in it can be worth anywhere from $300.00 to over ten thousand.

The cost of onyx varies, depending on where you buy it. Black onyx may cost more, as the demand is higher in the U.S. Mexican onyx can be really cheap, but also depending on where you buy it. For example, I have bought onyx for as little as $3 (authentic Mexican onyx from St. Xavier Chapel in Tucson, AZ), yet have also purchased Black Onyx set in pure platinum for as much as $500+.

Broadly speaking, not much. Will vary due to several factors, eg: whether it's free of cracks, whether it's true silicate onyx or the far more common carbonate called onyx, quality of color and pattern. More than a few bucks per pound would be most unusual.
The value of a 10k gold ring with a black onyx stone can vary based on factors such as the weight of the gold, the size and quality of the onyx, and the design of the ring. Generally, the gold content in a 10k ring makes it less expensive than higher karat gold, usually worth around $20 to $40 per gram for the gold alone. The onyx stone, depending on its size and craftsmanship, might add an additional $20 to $100 or more. Overall, the ring's worth could range from approximately $100 to $300, depending on these variables.
