How much does an Algordanza diamond cost?

From roughly 3,500 Swiss francs (about $3,900) for a 0.3 carat rough stone, rising with carat and cutting. Payment plans start around $100 a month.

Why are Algordanza diamonds blue?

The boron naturally present in a person's remains enters the diamond lattice and tints it blue. Algordanza doesn't treat the color, so the depth of blue is unique to the person and can't be predicted exactly.

Where are the diamonds made?

In Algordanza's own facility in Switzerland, with ashes transported by secure courier and the finished diamond returned the same way.

Algordanza Review: Swiss Memorial Diamonds

Algordanza has grown memorial diamonds in Switzerland since 2004, known for naturally blue-tinted stones and Swiss-made precision. Here is what to expect and what it costs.

Who Algordanza is

Algordanza is the most established European name in memorial diamonds, with the ashes couriered securely to its Swiss facility and a US arm handling American families. It is also the only maker in the category running entirely on renewable energy, which matters to some families choosing cremation for environmental reasons.

The signature blue

Algordanza does not color-treat its stones. The boron naturally present in a person's remains tints each diamond a shade of blue that cannot be predicted in advance, so the color that emerges is genuinely the person's own. Families either love this or prefer a maker who controls the color; it is the defining choice about Algordanza.

What it costs

Prices start around 3,500 Swiss francs (roughly $3,900) for a 0.3 carat rough, uncut stone, with cut stones and larger carats costing more, up to a 1 carat brilliant at luxury-jewelry money. Six cuts are offered, payment plans start near $100 a month, and rough stones offer a saving for families who like the unpolished, as-grown look.

Our verdict

The craftsman's choice: Swiss process, renewable energy, and a blue that is authentically your person's own chemistry. Prices sit near Eterneva's, so the decision is really about whether the natural blue and European handling appeal more than the American experience-led approach.
