Algordanza diamond clarity

Algordanza developed a very high-quality purification process to extract pure carbon from cremation ashes in 2003 and has been constantly improving it ever since. Our processing creates carbon that is 99.99% pure which grows beautiful colourless to blue diamonds.

Colourless and blue memorial diamonds are the most difficult to grow, Algordanza specializes in these very rare and precious cremation diamonds. When ordering multiple memorial diamonds from the same carbon source, the cost is reduced by 10% for every diamond after the first, since processing only occurs once.

More than 80% of all Algordanza diamonds have a clarity value of VS1 or above.

Algordanza offers six cuts for cremation diamonds; Radiant, Princess, Heart, Asscher, Brilliant and Emerald. Having a memorial diamond cut costs more than leaving it rough (uncut) all cuts cost the same except for the heart cut.

The heart cut costs £500 GBP more due to its complexity and cannot be made on small diamonds because the cut needs a larger surface area.

Superior technology

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.

Algordanza also has the most sophisticated HPHT presses made in Germany.

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.

3 diamonds from ashes - due to boron, cremation diamonds are dark blue to colourless

Diamond colour facts

Due to the element boron ligated to our bodies naturally, ALGORDANZA cremation diamonds can be perfectly 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 impurities have been introduced into the carbon accidentally through poor processing or intentionally into the diamond grid. Such processing is less expensive because less time and poorer quality chemicals are used. Red, pink and green diamonds cost slightly more than yellow diamonds, since they are yellow diamonds that have been bombarded with radiation to change their colour, also causing the diamond lattice to break down, making them weaker.

ALGORDANZA does not influence the colouration of their 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 or uncut 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.
