I think the white mineral is scolectite. It gets sold at a lot of mineral shows because it comes from India cheaply with other zeolites. But it is fancy and fun. I have a few. https://en.wikipedia.org/wiki/Scolecite
Just received these photos from my neighbor who came to visit me on the Easter holidays. The first item is a Judean lamp. The second seems to be a Byzantine mosaic ( 120 cm x 80 cm). He said the mosaic has been very recently unearthed. I just liked to share them on this dear lovely site. Thanks for watching. `
I would guess the first was a sea urchin fossil of some sort, and the geode is quartz crystals inside. Geodes can have several different shades of quartz, amethyst, rose, or crystal clear. Natural or artificial radiation can produce smoky quartz. Hard to tell some rocks and minerals from photos, but it sparks an interest.
Pretty sure the first is brain coral. The second could have many different colors inside. You can break it if you like and check it out. Or saw it open smoothly if you have the right kind of saw.
Ignore that poster. He is a troll who got his feelings hurt because he kept posting fake coins and some of them got posted to a fake coin reports website. You will probably get some help later when more members are online.
Jewelry making depends on your skill, but almost Anything can be made into jewelry, although rather expensive tools and training may be needed. I see a lot of stuff on craigslist and etsy, I would never want, but a younger person or culture might love. There are several jewelry making sites on google and utube with practical help. I mainly do faceting, and I purchase the metal work from Rio Grande supplies to add my gemstones to when finished, Jim
Hopefully the Ancient guys will let me continue this thread a little, with my minerals ( crystals). I was faceting a very nice African garnet with IF characteristics, no inclusions or defect, large enough for a 10+ mm stone. I had done the pavilion , the ice cream cone bottom part, the girdle which sets the size and is use to orient where the crown, the top part. Then you have to transfer the stone upside down by attaching the pavilion side to another dop (stick), separating it on the first joint and then on. I decided to take photos, but didn't think of it until I had done the bottom and transferred it. So here is the crown with the first facets in place. Hard to focus properly with one hand, The top is rough. The bottom of the brass dop is 1/4". Here the second level of facets are in and the table ( flat top ) is set and each group is them polished. The finished stone 10.02mm across. Nice color and internals. Then as I mentioned in the previous post, I used commercial jewelry supply for the metallic parts. And this would be the type of advert. photo if I was going to sell it, but they grow on you like ancient coins, hard to let go. Jim forgot its 4.135 ct, finished
What a fun hobby! Nice job on that garnet Being a gem cutter, are you familiar with John Dyer? He's like a rock star in gem cutting. I met him at a Tucson show a few years back. Man... I wanted everything he cut. I've not done any faceting but I have a bunch of Ethiopian opal rough (from that same gem show, it was one of the first years that Welo opals were flooding the market). One of these days I'll try some free-form carving. Have you done any opals?
Some of that Ethiopian opal rough: One of them after initial removal of matrix: (I never finished it ) Some gorgeous spessartite garnet rough from the same show. I'm going to leave it rough.
Nice gemstones Jim and Tif, I enjoy seeing them and learning how they are facetted. I am sure many other people in our community will too.
I am rocking on record store day in the Virgin Islands. Got another guitar pick for the collection. This one is from Tommy August and the Rum Syndicate. Also some fossilized coral for fun. Rocks rock.
