1'' 20mm Small Color Crystal Faceted Optical Prism Beam Splitter Physics

These are beautiful on a windowsill and throw colours all around the room🌈

Great for giving abstract light effect

Lovely little item.

Smaller than I expected, and it rarely makes any interesting reflection even in direct sunlight. But it's cute, and interesting, and makes a nice addition to any flat surface.

Bought a few of these for an art piece and i absolutely love them. They are so beautiful to just look at and move around and watch the light and colours they produce. My favourite purchase of 2024

There was a slight chip in the top peak of the one that I bought. It gave the top of it a scratchy-sharp feeling, when moving a finger over it. I almost returned it and did start a return process, but ended up keeping it. ........... Quite a nice item otherwise.

Fascinating gift for my grand daughter who plays regularly with it and loves the generated light effects

That one was for me 😃 I couldn't resist the colour plays inside this mini cube and the different shapes when the light refracts through it. Very cute.

Klein aber fein.

I gave this to my son for his 4th birthday. He's had it for over 2 months now and still likes to carry it around and show it to people. It is both educational and beautiful. The crystal is very clear and when you shine a flashlight (or sunlight) through it on one of the correct sides, it beams colored spectrum light onto the surrounding walls/room. The crystal has 2 crisscrossing planes inside of it that form a 3-dimensional X within the cube. These provide the refracting capabilities and also why you have to shine the light in the correct direction through the crystal for it to show the spectrum. Overall, a neat gift to give to a child which can also be used to educate them on the light spectrum.

No matter how I view this Crystal construction it's mysterious and lovely. The colors depend on the angle of observation and available light being reflected and refracted through the various crystal assemblies. No one can pass it without a bit of surprise at all the amazing colors as they shift and change. It's small but it's powerful.

This thing is way more beautiful than it shows in the pics! Do not expect a traditional pure prism, this is not that. Each facet has filters that filter out and reflect a specific wavelength/color of light. Sometimes you can witness TIR or Total Internal Reflection too if you have the angle right, which is super cool to me as an optics nerd (Schmidt-Pechan vs Abbe Koenig prisms in binoculars, telescopes, etc) Its just a really pretty trinket, but not a traditional "rainbow" prism so dont expect that. I would buy again, I got the 25mm cube, thinking about getting the polyhedron now. It is so beautiful in sunlight and fun to play with different colors of lasers. But be careful in sunlight or with lasers! Wear eye protection! Some reflections can catch you off guard and are not necessarily what you would expect! Be careful. But its beautiful and packaged nicely. Only room for improvement would be if it came in a small velvet/microfiber sack or with a cloth to keep fingerprints off. Or a 3 pronged stand on which to hold it up, off centered. So cool to watch it in the light and turn it and see from different angles.
