Semiprecious stones like amber or lapislazuli

unveiled this in the jade thread, though it really belongs here. I'm thinking the green bead is aventurine, but would appreciate help with the others?

And a follow up to show the banding in the carnelian beads in the previously posted bracelet.

Anyone know about the fluorescent qualities of semi-precious gemstones? I know treated jadeite is likely to glow under short wave or long wave UV light... I just shone mine on my beads... nothing glows except the pearls.

Really pretty rings! I love lapis and onyx and turquoise... diamonds always just kick everything up a notch!


Not a full list, but lot of well known gemstones are listed and I like how they have a lookalike chart, too.

Thank you for that link... since the pearls glow, I'm going assume they are cultured.
 
And yes, here are more beads. :p

This one was an impulse purchase because I stumbled across the auction only a few hours before it closed. I don't think I examined the pictures closely enough. The seller mentioned the gray links as a possible repair, but until I had it in hand, I didn't really notice the other flaws, and they aren't specifically described but they are visible in the seller photos.

Most of links are really stretched out and the clasps links look they were broken off and the end twists just looped through. There is an odd key ring style jump ring attached to the clasp loop on one end. It almost makes me wonder if the whole bracelet was broken and then put haphazardly back together, or if the clasp part even goes with the beads and might just be a franken-add later on.

I'm thinking about seeing if I can find a jeweler that won't charge too much to put in gold links for the gray and properly solder the clasp loops down.

I still like it, though. The beads are bigger; closer in size to my green nephrite beads. Sorry for the horrible lighting.

Im going to show 3 gems under UV light, the results are pretty neet! 1st & 2nd is tugtupite, usually red with white matrix-shows bright orange under UV, next is alexandrite, usually shows a bright red under the UV, the last is red spinel, burmese. These stones, 3, are all burmese & do show pretty well under the UV, mother nature showing her stuff.-stevie...

Hi!

Gold-filled jewelry is not actually an alloy of gold the way 10, 14, 18 karat gold is, but it is still pretty and usually brings down the cost while still achieving the look.

https://en.wikipedia.org/wiki/Gold-filled_jewelry

According to wikipedia...

Gold-filled jewelry is composed of a solid layer of gold, which must constitute at least 5% of the item's total weight, mechanically bonded to sterling silver or a base metal. The related terms "rolled gold plate" and "gold overlay" may be used if the layer of gold constitutes less than 5% of the item's weight.

In the United States, the quality of gold-filled is defined by the Federal Trade Commission (FTC). If the gold layer is 10 kt fineness, the minimum layer of karat gold in an item stamped GF must equal at least 1/10 the weight of the total item. If the gold layer is 12 kt or higher, the minimum layer of karat gold in an item stamped GF must equal at least 1/20 the weight of the total item. The most common stamps found on gold-filled jewelry are 1/20 12kt GF and 1/20 14kt GF.


hope that helps!
