Which stone is more valuable onyx or topaz?

Answer 1

Definitely topaz, onyx is much more abundant and is usually dyed (which is an accepted practice), if the topaz is natural, its worth much more. There are different types of topaz and colors as well. Some topaz can be very cheap like mystic or blue topaz which are both heavily treated and mass produced. But blue topaz can be natural too, in that case it would have some worth. The most valued topaz is natural imperial topaz. Sorry it may seem confusing why some topaz have more value and others do not; it all depends on whether it is natural or man-made/heavily treated--with the natural topaz having the most value and the man-made/heavily treated topaz very cheap. A lot of times you can tell the value of a gem by how well it is cut (but that's a whole other topic).

Answer 2

The value of a stone is determined by multiple factors such as its quality, size, color, and demand in the market. Generally, topaz is considered more valuable than onyx due to its greater rarity and popularity. However, the specific value of each stone can vary depending on these factors and individual market conditions.
