Question about vintage Italian gold

I'm a new member, and I hope that members may be able to give me some ideas. I collect Italian gold jewelry, from the 1980s and 90s, in a particular style. I comb US and European Ebay, always on the lookout for pieces. Occasionally, some nice pieces will turn up on Italian sites, that deal in used jewelry, but unfortunately, Italian law does not permit shipping to the US, although Ebay is an exception to this law. I can search in Italian, French, German, Greek, and Spanish (and no, I don't speak all these languages!) So, my searching is pretty thorough, I think. It's becoming more and more difficult to find pieces in this style. And it's not just style, but also the quality of manufacturing, how the piece is finished, and other small details. I'm interested mainly in necklaces and bracelets, in 18k yellow gold (although I'd look at 14k too), with a rolo link chain, some type of stone, precious or semi-precious, and some whimsical design feature, like hearts, stars, moons, or beads. I'm very sorry that I have to post links, but I will learn how to post images to this site! Here are just a few examples of the type of pieces I'm always looking for:

I know that these designs were mostly produced in the 1990s, and I used to know which manufacturers in Italy produced these designs, but, because they were available at the time, I didn't keep a list. I know this is a long shot, but I was the highest bidder on one of the pieces pictured, and was sniped in literally the final second of the auction (even the seller couldn't believe it happened), so it's becoming harder and harder to find these pieces.

If anyone had any ideas, I would love to hear them, and thanks!
I should add, that there are a few pieces of this type on Ebay currently. However, they tend to be heavier (and more expensive than what I'm looking for.) In 1996, I bought an Italian gold necklace in Toronto. I lost it (and I *never* lose jewelry), and I had it copied. The jeweler did a very nice job, but the same details weren't there, which is why buying the vintage stuff is so important.
