3D Crystal Arc – A Beautiful Keepsake

3D Crystal Arc - A Beautiful Keepsake

3D Crystal Arc is the perfect way to preserve those special memories. It is a gorgeous keepsake that will surely catch the attention of everyone who sees it.

The sonic crystal has non-symmorphic lattice symmetry without mirror, inversion or roto-inversion symmetries and bosonic time-reversal symmetry. The gapless topological surface consists of a chiral nodal plane spanning the Brillouin zone.


If you want to give a gift that will be cherished by the recipient for a long time, then consider getting them a 3D Crystal Arc. This beautiful paperweight is made from a high-quality crystal that can be engraved with an image or text to make it even more unique. It’s a perfect gift for anyone who has been through hard times and has overcome them.

Molecularly, Arc interacts with more than 30 validated interaction partners and has been implicated in the regulation of intra-cellular signaling and plasticity through its interaction with clathrin adaptor protein AP2, dynamin 2, and endophilin. These interactions promote clathrin-mediated endocytosis of AMPA-type glutamate receptors and decrease synaptic strength during LTD.

Crystal structure analysis revealed that the Arc CT domain has strong structural homology to the Gag capsid (CA) domain of HIV and Rous Sarcoma virus. Like Gag CA, the Arc CT domain is composed of two globular domains, termed the N-lobe and C-lobe, which self-assemble to form a capsid shell.


We offer a wide range of personalization options that include etching a message or even an image into our crystal products. Our team takes care of every detail, from start to finish, so you can rest assured that the personalized gift you order will leave a lasting impression on its recipient.

Whether it’s the day your loved one got married, had a baby, or achieved some other milestone, commemorate their special moment with this stunning 3D photo crystal. They’ll be proud to display this keepsake on a mantle or bookshelf, and it will serve as a reminder of their best memories.

Under its grille, Arc hides 11 high-performance drivers—including two built to aim upward for Dolby Atmos and overhead sound. This unique design allows you to create a huge audio soundscape without the need for multiple speakers and components. Fine-tuned by Oscar-winning sound engineers, Arc delivers clear dialogue so you can follow the action. Setup is simple with just two cables and step-by-step guidance in the Sonos app.


We provide two engraving options for our custom crystal awards – a 3D image or a flat logo. The engraved images can take many forms, including an organizational icon, an organic figure, or a geometric design. This customization allows for a unique and personalized award that is sure to impress the recipient.

Recent structural analysis of the Arc CT domain reveals 3D homology with the Gag capsid (CA) domains of HIV and Rous sarcoma virus. Moreover, ligand binding to the Arc CA N-lobe triggers a conformational change that inhibits temperature-induced oligomerization. In addition, a recent study has shown that Arc interacts with various effector proteins to regulate synaptic plasticity and intercellular communication. For example, ligand interaction with Arc increases clathrin-mediated endocytosis of AMPA receptor GluA1 subunits and promotes decreases in synaptic strength during LTD and synaptic downscaling. Moreover, ligand binding to Arc has also been shown to activate the histone acetylases TIP60 and CREB. This mechanism is critical for regulating neuronal activity and plasticity.


Circular arc crystal paperweight with The Eiffel Tower etched inside. Custom logo or text can be engraved as well. Packaged in a satin lined presentation box.

Featuring eleven precisely engineered internal speakers, including two dedicated height channels, Arc fires sound in all directions—returning every whisper and explosion with dramatic clarity, detail, and depth. Fine-tuned by Oscar-winning sound engineers, Arc also makes it easier to hear dialogue when characters speak and the action intensifies.

With a variety of sizes available, you can choose the one that fits your space best. And with our shipping protection, you can rest assured that your gift will arrive safely at its destination.
