As the saying goes: gold has a price but jade is invaluable. This "invaluable" does not mean that any jade must be more precious than gold, but means that in the jade business, there is no fixed standard for the seller to quote the price of a piece of jade material or a trinket, and there is great elasticity in between. If someone quotes a high price, and you like it, then buy it. If you like it, it's worth it; if you don't like it, even if the price plummets, you won't pay for it, thinking it's not worth it. Another meaning is that the factors determining the price of jade are multifaceted. For example, a piece of Myanmar emerald or Hetian white jade, due to differences in jade quality, carving skills and age, etc., the prices can be worlds apart.
