A real diamond

A Semper Fides diamond has the same physical, chemical and optical properties as a mined diamond.

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

Frequently asked questions

Is a pet memorial diamond a real diamond?

Yes. A Semper Fides diamond has the same physical, chemical and optical properties as a mined diamond.

What do you need from me to make the diamond?

We only need 250 g of ashes, and the rest stays with your family. If you have less than 250 g of ashes, 11 g of fur can be used instead. If you hand in 250 g or less, all of it is used; any extra ashes handed in beyond 250 g are not returned. If our analysis finds too little carbon, we can first add your pet's fur, or a fabric item or soft toy made of cotton or another natural fibre (purely synthetic items can't be used), to top it up, for HKD 990, charged once. If that is not possible, we propose a Stailas diamond, made with a personal item of your pet (see "What is a Stailas memorial diamond?"). If you prefer neither, you can cancel the order: the ashes are returned at no cost, and we refund 90% of your deposit, less any shipping costs already incurred.

What is a Stailas memorial diamond?

Fur or a personal item of your pet (Stailas) is only a fallback when the ashes do not contain enough carbon. For a Stailas memorial diamond we ask for a personal item that once belonged to your pet. Carbon is extracted from the item and added to the carbon from the available ashes. Please contact us to find out more.

Can I combine ashes and fur?

Yes. The price includes one source (ashes or fur). Adding a second source costs HKD 990, charged once.

How long does it take to create a diamond?

Production usually takes 4 to 9 months, depending on the size of the diamond and the number of orders being processed in Switzerland at the time. Jewellery mounting adds extra time.

What are the steps, from the first visit to collecting the diamond?

First, book a free 40-minute consultation at our North Point showroom; there is no need to decide on the day. Second, hand in 250 g of your pet's ashes (or 11 g of fur if there are fewer ashes), confirm your order and pay a 50% deposit. Third, we send the ashes to our Swiss laboratory in two separate parcels, as a safeguard. Fourth, the diamond is made in 4 to 9 months. Fifth, you collect it at the showroom by appointment and pay the remaining 50%.

How do my pet's ashes get to Switzerland?

We send the ashes to our Swiss laboratory in two separate parcels, as a safeguard. One tracking code covers both parcels.

Is a pet diamond made from fur only cheaper?

No. The HKD 4,090 reduction for hair-only diamonds applies to memorial diamonds for people only. A pet memorial diamond made from fur is priced as listed, from HKD 18,830 for a 0.25 ct raw diamond.

Can I cancel my order?

Yes. You can cancel your order at any time before production starts, and we understand that plans can change. Production starts when we begin processing your ashes or fur. The refund is 90% of your 50% deposit (a 10% administration charge applies), minus any shipping costs already incurred. Before shipping costs, that is 45% of the order price.

How do I collect my diamond?

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

Can I return my diamond?

Because each diamond is made to order for you, there is no return period once you have received it. If you have any questions before production starts, we are glad to talk them through.

Where is a pet memorial diamond made?

Semper Fides has its own chemical laboratory and growth machines in Switzerland, where your pet’s memorial diamond is made.

How much does a pet memorial diamond cost?

Prices start at HKD 18,830 for a 0.25 ct raw diamond. The price depends on the size and whether the diamond is raw or cut and polished. Special cuts (Emerald, Asscher, Princess, Radiant, Heart, Oval) add HKD 3,150, and brilliant cut is included. The price includes shipping of the ashes (or fur) to Switzerland and of the finished diamond back to Hong Kong. You collect your diamond in person at our North Point showroom by appointment.

Will my pet’s diamond look different from others?

Each diamond is unique. At times, fine inclusions from your pet’s remains may be seen in the diamond.

What happens at the free consultation?

It is a free 40-minute consultation to explain the process. It is pressure-free. English consultations are available by advance booking. Showroom visits are by appointment: Mon-Fri 10:00-17:00, Sat 10:00-12:30.

How does payment work?

You pay a 50% deposit when you order, and the remaining 50% when you receive the diamond.
