Silver Mementos

Please enter a valid date

Celebrate the most important event in your life with your personal Solar System. 

Your Memento will be the most precise and accurate depiction of the Solar System commemorating the personal date of your choosing. 

The latest NASA data and algorithms are used to compute precisely the positions of the planets and their orbital paths.

Made to order. Please allow 8 - 16 business days for the production.

We believe our designs are the best on the market because we have combined scientific data with an artistic dimension to make beautiful yet accurate renderings. We use the latest NASA data and algorithms to compute precisely the positions of the planets and dwarf planets, as well as their orbital paths. We have tested our output extensively against results available on JPL's systems because we strive for the best quality and accuracy. 

We then process the numbers in a 3d projection to generate a depiction of the Solar System that is unique to the date you requested. No two different dates produce the same design, that's why SpaceTime Coordinates products are so distinctive and personal. We generate the graphics uniquely and carefully for each order we receive to make sure that your STC item represents *your* special place in space and time.

Material Finishes

We use Lost-Wax Printing and Casting. This means we first 3D print your model in wax and then cast it the traditional way.

Raw Sterling Silver is mechanically polished so may show print lines and have a rougher surface texture.
Polished Sterling Silver is lightly hand polished to achieve a smooth finish but still can have some surface texture.
Premium Sterling Silver is highly hand polished to a "wet" sheen and looks very shiny.

How it's 3D printed

3D Printed Sterling Silver products are made using a three-step process. The products are created with a lost-wax casting process using a high-resolution 3D wax printer. The 3D printed wax model is put in a container and liquid plaster is poured around it to create a mold. After the plaster sets, the wax is melted out and molten silver is poured into the plaster mold. The plaster is then pulled away to reveal the silver and the finished product is polished for a smooth surface.


All Silver will tarnish over time.
