Hi all. New here, been tumbling for a year, so, still new. Labradorite finds in a salted bucket.
My question: would labradorite be hard enough to tumble with amethysts? TIA!

Welcome from Missouri. Lots of tumblers that probably have the answer to your question. I haven't tumbled Labradorite. Just finishing up some amethyst and it was very hard.

I would not mix labradorite, a feldspar, with amethyst, a quartz. Labradorite is a hardness of 6-6.5 as where amethyst is 7. And a difference of 1 is significant.

Hi all. New here, been tumbling for a year, so, still new. Labradorite finds in a salted bucket. My question: would labradorite be hard enough to tumble with amethysts? TIA! Labradorite is typically too soft to mix with Amethyst, but the hardest Labradorite & the softest Amethyst could work together in a tumbler...... In general, any rock/mineral that has a hardness of 7 or higher can damage Labradorite. Any rock/mineral that has a hardness of less than 6 can be damaged by Labradorite. Safe to tumble with Labradorite: this is not a comprehensive list by any means.... there are over 6000 known minerals and new ones are discovered every year. Amazonite 6-6½ Andesine 6-6½ Anorthoclase 6-6½ Benitoite 6-6½ Bixbyite 6-6½ Bytownite 6-6½ Chondroite 6-6½ Helvite 6-6½ Hyalophane 6-6½ Labradorite 6-6½ Marcasite 6-6½ Microcline 6-6½ Nephrite 6-6½ Norbergite 6-6½ Oligoclase 6-6½ Petalite 6-6½ Prehnite 6-6½ Pyrite 6-6½ Rutile 6-6½ Sanidine 6-6½ Smaragdite 6-6½ Sugilite 6-6½ Tantalite 6-6½ Xonotlite 6-6½ Zoisite 6-6½ Somewhat safe to tumble with Labradorite: meaning in the hardest form of these, they may scratch Labradorite. Axinite 6½-7 Chalcedony 6½-7 Chrysoprase 6½-7 Diaspore 6½-7 Ferro-Axinite 6½-7 Gadolinite 6½-7 Grossular 6½-7 Hiddenite 6½-7 Jadeite 6½-7 Jasper 6½-7 Kornerupine 6½-7 Kunzite 6½-7 Mangan-Axinite 6½-7 Peridot 6½-7 Pollucite 6½-7 Serendibite 6½-7 Sinhalite 6½-7 Spodumene 6½-7 Tanzanite 6½-7 Thorianite 6½-7 Tinzenite 6½-7 Magnesio-Axinite 6½ Nambulite 6½ Vesuvianite 6½ Cassiterite 6-7 Clinozoisite 6-7 Epidote 6-7 Hancockite 6-7 Pyrolusite 6-7 Sogdianite 6-7 Most of these I've never even heard of before! |

While hardness would probably be a big issue, a more important one IMO is that Labradorite has perfect cleavage in two directions that intersect at approximately 90 degrees. Amethyst quartz is not only much harder but has no cleavage planes. Labradorite would likely end up as little broken chunks in a rotary tumbler especially.
