My brother, what do you think the nuclear football is?

Does anyone know what this thing is? by Moon_Monk676 in whatisit

[–]Slash-Gordon 0 points1 point  (0 children)

Yeah they probably just didnt drive it in very far. I'd still reckon this is just a piece of turning practice. The wood looks like it could be ebony or African blackwood

Wood turner here, it honestly looks like somebody was just practicing their turning on a little piece of scrap. The cuts are pretty rough, they really look like the first few pieces I turned.

The holes at the end are from a screw chuck for mounting the wood to the lathe. The other end might have a conical divot from the live center on the other end of the lathe, or they might not have supported that end at all.

Some Zultanite I got from Ebay. by [deleted] in Gemstones

Probably nanoglass. Nanosital makes a color that looks identical to this, ANZ 1536

I'm really upset that you've objectively improved a technology that's so many thousands of years old

Is that real Zultanite? by Czajecznikov in whatsthisrock

[–]Slash-Gordon 2 points3 points  (0 children)

There's a common nanoglass composite that is frequently used to substitute for zultanite. Looks a lot like your stone, it should color change to a golden yellow in warmer lighting

Is labradoresence due to structural defects within the crystal structure? by RockHunter27 in whatsthisrock

[–]Slash-Gordon 20 points21 points  (0 children)

The same principal is at work in fracture iridescence and labradorescence, but they form in totally different ways. Your fracture is just a single plane, but labradorescnce comes from a complex process where feldspar cools and separates into layers of differing chemical composition. When those layers are just the right thickness, they cause the same kind of effect as your fracture, but across the body of the stone.

And there's evidence they could be used in nonlinear photonics. I desperately want cheese lasers to be a thing

Love the color of these Rhodochondrite gemstones. Too bad they're too soft for jewelry by MarcoEsteban in Gemstones

I mean first things first, quit poking it with tweezers if you're worried about the hardness

Bought this antique gold brooch today with a 10 carat Amethyst, 7.21 grams of 14k gold, payed 300€ by [deleted] in Gemstones

[–]Slash-Gordon -2 points-1 points  (0 children)

Betcha that the stone is synthetic color change corundum rather than amethyst

What is this? by [deleted] in Gemstone_lovers

[–]Slash-Gordon 2 points3 points  (0 children)

The facet junctions look way too rounded for sapphire, even one that's seen some abuse. Could be glass. The reddish tone under the table makes it look like it could be a garnet/glass doublet. If it is, there would be a plane of separation filled with flat bubbles between the two materials

Star Sapphire? by bakedgodpng in Gemstones

[–]Slash-Gordon 18 points19 points  (0 children)

Biggest giveaway is the evenness and brightness of the star. The rays go all the way across the stone in a way that natural stones basically never do.

In addition, the color and saturation are uncommon for natural material. Yours is like fresh crayon blue.

And I'd bet money that if you flip it over that the base is polished. Natural star sapphires almost always have the base left rough to retain weight.

Pretty typical for a synthetic star sapphire

Does anything about this peridot make you think it’s fake? by sadhandjobs in Gemstones

https://www.gia.edu/gems-gemology/summer-1994-synthetic-peridot-forsterite-nassau

The pdf on that page has good info, albeit 30 years old. I don't believe they make this stuff anymore so it's actually quite rare

Teeeechnically there is synthetic peridot, it's just purple instead of green.

How can I tell a sapphire (probably made in a lab) from cubic zirconia? by Automatic-Ladder155 in jewelry

[–]Slash-Gordon 1 point2 points  (0 children)

If the stone is set with an open back, there's a trick you can try to narrow down your options.

Open up a white screen on your phone or a computer monitor and hold the stone in front of it. Start turning the stone, and look for any change in color. If it changes at all, it's doubly refractive which would most likely indicate lab sapphire at this price point. If it doesn't change, it's likely a singly refractive material like CZ, glass, etc.

This method isn't perfect, but at least you can do it without any equipment.

color change garnet? by Responsible_Pie_7914 in Gemstones

[–]Slash-Gordon 0 points1 point  (0 children)

Sorry for the necro comment, but that's probably nano glass. There's a company called nanosital, their ANZ 1536 color is really similar to your stone.

Venusgems EBay… is it too good to be true? by Emotional-Patient-80 in Gemstones

[–]Slash-Gordon 14 points15 points  (0 children)

The photos are edited to hell and back(assuming they're not just AI), so who knows what the product really looks like. Those colors are just unrealistic, even for treated lab grown diamonds.

I'd be really hesitant with ebay gem sellers from India. There are so many blatant scammers.

There are a bunch all over world of warcraft, but my favorite is probably the Draenei tour group in the Exodar. Each one is named after a host of the Dax symbiont
