HDCRYSTALGIFTS Color Cube Prism 20mm K9 Optical Crystal Glass Polyhedron RGB Dispersion Prism for Physics,Photography,Desktop Decoration

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

Lovely little item.

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

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.

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.

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.

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

My son loves this crystal. He puts it on his window sill to catch the sunlight and loves watching the rainbow lights appear on his wall. He keeps it in a box with all his precious treasures. I love it too!

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.

Exactly what I was looking for. This trichromatic cube is on the smaller side, but still demonstrated light refraction of different colors of light as you rotate the cube. My students were mesmerized. It was absolutely worth the cost. Now I want a 2nd one to show the secondary light refraction!

Made of glass this prism is precious! I have it on a table and it always surprises me with a colorful display. Obviously not a toy for small children but a joy to have in my home!

Nice crystal!
