Algordanza diamond clarity

Instead of one large memorial diamond, up to four smaller family diamonds can also be made from the cremation ashes. In this way you enable several family members to always carry the memory of the loved one with them.

When ordering multiple memorial diamonds from the same carbon source, the cost is reduced by 10%, since processing only occurs once. Family packs of diamonds are only available in Brilliant cut.

Variations in diamond growth

Since a diamond actually grows over time, the diamond’s end carat size could be slightly smaller or slightly larger than requested. If the diamond is smaller, the price will be reduced, however if the diamond is larger, the price will not increase.

Superior technology

Algordanza HPHT presses are made in Germany and specifically engineered to make Memorial Diamonds.

In order for a lab grown diamond to understand how it should grow, a real diamond seed is needed to start the diamond synthesis. We use real diamonds to start the growth process.

The larger the cremation diamond should be, the longer it needs to stay in a controlled environment in order to properly grow, which is a major cost factor in time and energy.

Diamond colour facts

ALGORDANZA does not influence the colouration of their diamonds.

Due to the element boron ligated to our bodies naturally, ALGORDANZA cremation diamonds can be colourless (very little boron present) or be very dark blue (large amount of boron present).

If a cremation diamond is yellow, amber or black, then nitrogen and other impurities have been introduced into the carbon. Red, pink and green diamonds are yellow diamonds that have been bombarded with radiation to change their colour, also causing the diamond lattice to break down, making them weaker.

Colourless and blue diamonds are the most difficult to grow, Algordanza specializes in these very rare and precious memorial diamonds.

Rough diamonds cost less

Diamonds from ashes or hair that are rough (uncut) are simply polished to remove sharp edges, which reduces threir price compared to a cut diamond.

More unique

Rough diamonds are preferred by many clients because they reflect their loved one’s “Rough Edges”, both having been naturally formed. No two rough diamonds are the same and are therefore unique.
