I found this last summer in a 1880-1890 dump looks like it might have been in a tin of some sort when I dug into it. The tin was just powder I broke the amber piece when I hit it with the shovel but all the rest are intact.
Sorry I should clarify...by amber I ment the color not fossilized tree sap. It is actually citrine (yellow Quartz) The braclet is amethyst, the neckless apears to be lapis
Have you had a jeweler check them? Some costume jewelery can be worth quite a bit of money. As a matter of fact some of it can be worth thousands. Check for carat markings on the catches, jump rings and any solid piece large enough to mark. (10K, 14K) If there are none it could still gold but it would have to be checked.
Some of the stones look like they could be real. Plastic jewelery has been around for over 2000 years.
The pink stone bracelet looks like tourmaline in (possibly) rose gold. Clean it with a tooth brush and tooth paste and it should shine right up. Patina on jewelery is called dirt. Jewelery should be clean and shiny.
Big jewelery in the in thing right now and gold is over $1000 an ounce. Could be some good stuff there. You guessed it....I am a certified jeweler/horologist. Should have finished my GIA certification and may yet.[]
My bet is that they were thrown out by accident, my guess is that the original occupants of the house died and someone very hastily cleaned out the stuff. There also might have been a fire at this house and things got thrown out during the clean out???
