I've been struggling with this stupid quartz for ages. Spent 30 minutes trying to polish one facet only for it to scratch at the very end. gently caress this I'm buying a new 1200 lap for quartzes

I don't cut quartz for this reason, tried it once and was like "nope, never again!"

It's a random piece of synthetic "sky blue" quartz I got that actually looks just white in person. My 1200 lap scratches the poo poo out of it and tbh its pretty scratchy on harder stones too. Sometimes the facets barely look better than my 600 lap, I thought it just wasn't broken in but I've used it on multiple stones at this point and it still sucks
Ever hear of 'shitrine'? It's a particular batch if synthetic citrine that went around the market for a bit which was famous for being almost impossible to polish. You could identify it because heating it turned it blue (due to cobalt doping for...some reason?)
Point is some quartz, and especially some synthetic quartz, is just that way inherently.
Your time is really too valuable to fight with uncooperative material anyway. Or with synthetic quartz in general. If you want to do some quartz richly colored natural amethyst is still inexpensive but the end result with precision cutting has a great multiplier on value. Or if you want something weirder, some nice lavender quartz with that opalescent translucency also rarely fails to hit.

Yeah, but this particular 1200 does that on like CZ and corundums too I'd actually love to get my hands on some rose de France amethyst or a pretty rose quartz, but since I've moved to europe I haven't really looked at what online rough vendors are around. Was hoping to hit up a gemshow or two at least but yay covid

Birds do not want you to know any more than you already do.

What's a reasonable price for a 16" 3mm domed omega sterling silver necklace? The one I got back in the 90s finally broke, and I need a replacement.

I see prices from $30-$90 on Amazon. I would prefer to shop at an actual jewelry store, but the good local one just closed so I'll need to drive a while or order online. I would also prefer not to buy from Amazon but I'm not sure where to look online either.

Any ideas?

It's not in great shape and I think multiple links are near failure, but here!

Sun was shining so I took a photo of the rutilated quartz and gold pendant I got for my wife from a local jeweller a couple of years ago. It's about an inch and a half long but I need to get the mounts adjusted as it tends to hang to the side when worn.

Sorry I totally spaced on this! I'd say amazon is an okay bet. If you can get to a local place that's great, but they'll be ordering it in from somewhere else.

I wound up with the $27 Amazon option just to see, and it's probably OK? At least for now, for what I use it for. I do wish I knew what was actually going on with the huge price spread, though!

Got a new 1200 lap and I'm about to start polishing attempt #3 on this lovely loving quartz. I don't think I could give it a better starting point so if this doesn't work I'm gona give up lol

My guess is just different companies having different profit margins, you'll probably be fine!

I got a 1200 lightning lap topper, it's definitely leaving a much smoother finish than my metal 1200 so fingers crossed lol
