Just received them, had done the magnetic charge test , was successful but I feel like taking them to antique shop to check them out but they float in salt water test even with this weight, I am thinking either to resell them or keep them sometime for investment, do you think amber will go higher? ?

Those are some ginormous beads! My mom has a true heirloom chunky round bead amber necklace from our Lithuanian great, great grandmother & its beads (also opaque) are nowhere near that big - also a deep orange color. Wondering about how this is strung - looks like just on a a piece of string...?

Actually it is just strong plastic string to hold the beeds together, I bout it in an auction from a person in San franchise couldn't believe that I got them, if I wanted to put them for sale, how much each necklace will be, the 1st necklace is 160g and 27 beeds each is 25mm, the 2nd one is 290gm of graduated beeds the smallest is 25mm and biggest is 42mm, I tried to search comparables, but can't find, can anyone tell at least an estimate? ?

Can Anyone help how much I should sell each for, somebody is interested, thanks

If you can sell them for 10% more than you paid you will be doing well.

Well any time you can make 10% on an investment in a few months you are doing well.
Besides you have said you are not sure of the quality, nor if they are pressed or not.
Put them up for auction....see what someone will pay?
If you think they are worth so much more, why would a dealer sell them to you so chaeply?

I couldn't leave this for uncertainty, I want to put a final comment so people can learn as I did,

First I want to send many thanks to all of you especially Jemdandy, I have learned a lot from your comment, was really honest positive and very informative.

2nd, for these unique two baltic amber necklaces, it turns out that they are copal necklaces not as I bought them, I have contacted a really good russian amber dealer and sent him the photos, he told me that he thinks that it is copal and told the only test would show the difference between amber and copal not ultraviolet test not salt water floating test, but is the hot needle test smell, and here it goes, I did it and compared the smell of genuine amber, and it very difficult, it is copal, I hope other people would learn from this like me, thanks all.

I guess the lesson is...if it seems too good to be true.....you better know more than the seller!
Thanks for the added info.

It is absolutely true, but sometimes it is hard, when you buy what you like and it turns out fake, when I got these results I said to myself well I better go and check the other pieces I recently purchased from ebay, and guess what, only two pieces are genuine amber from total 7pieces, the rest even all look amber, float in salt water test, somehow have some magnetic charge, all copal the same awful smell with hot needle, but the good thing about ebay, I can return things, look at these pictures all fake amber

These are the real ones

Consider it college tuition....
And that's one of the problems with buying things you can't touch and hold>
Love that string of beads.....

Thank you for all the info.
