Made from them

Your companion’s ashes or fur become the diamond. Each one is unique, and fine inclusions from the remains may sometimes be seen. They are part of what makes it yours.

Made in Switzerland

Created in a laboratory in Domat/Ems, Switzerland, dedicated to pet memorial diamonds. Algordanza has made memorial diamonds since 2004.

Words from families

“It feels like I’m losing part of my soul when Max left me. I spent my last 10 years being him and he is my best friend, my son, my partner... Thank you for the amazing service and the stunning memorial diamond. After I received the memorial diamond, I inlaid “him” into a necklace. I couldn’t be any happier while wearing him to walk around the places he loved.”

Crystal Cheung

“Algordanza created a beautiful diamond of my cat. She was with me for 8 years and she is my best friend in my life. And now this memorial diamond becomes a great companion to me and feels like she is always with me.”

Emily Li

Your finished diamond is collected in person at our North Point showroom by appointment, so we do not offer delivery.
