What is the amount of ashes required?

1. Natural Diamonds

2. What is the amount of cremated ashes required to create a memorial diamond

3. What if there isn’t enough ash?

In this post, we will be focusing on the amount of cremated ashes required to create a memorial diamond and what alternatives you may seek when there isn’t enough ashes.  


1) Natural Diamonds

Carbon is one of the most important chemical elements in the universe, taking on many forms and appearances, the most valuable being the diamond. Others include a myriad of organic and inorganic substances, but pure carbon on its own, has three major forms of appearances- coal, graphite and diamonds.


The majority of diamonds found in commercial mines and deposits were formed in the Earth’s mantle. Through violent volcanic eruptions, they were brought to surface in large chunks of diamond-containing rocks called xenoliths. However, before these eruptions could even bring anything to the surface, the diamond would have had to be created in a “diamond stability zone”.  A temperature of over 1000 degree Celsius and very high pressure is required and this case, these conditions can only be found deep beneath the Earth’s surface[1].

2) Amount of cremated ashes needed to create a memorial diamond

At Algordanza, a common question we get is "How are memorial diamonds made?" there are 5 steps to creating a memorial diamond. In the second step of creating a memorial diamond, carbon extraction occurs. How much carbon is actually needed from one’s ashes in order to create a memorial diamond? To make any size memorial diamond of up to 1 carat in size, Algordanza would normally request at least 500g of the cremated ashes, split into 2 separate air tight bags.  

3) What if there is not enough ash?

Regardless of size of diamond requested, 500 grams of cremated ashes are still required. In certain situations where there’s simply not enough ashes available, Algordanza is still able to conduct a composition analysis to check if there is enough carbon content to proceed with your order or not. In the case where there is not enough carbon, ashes will be returned at no cost and the order will be cancelled[2].


But what if you want to proceed with your order, despite not having enough ash? Well, in 2008, Algordanza established the novel approach, “Stailas” to help clients who would still like to proceed with the manufacturing of the memorial diamond.


Only natural materials that are combustible can be used to produce the diamond
in case there is not enough ash.


Algordanza  has made it a point to ensure the memorial diamond service is available in these situations as well. From experiences in Japan, a special type of diamond we call “Stailas”- The shining star in a revitalizing of precious memories was developed.


Under these special needs areas, personal articles (that are made up of natural materials that are combustible) that once belonged to the deceased will be requested (i.e. clothing, plush toys, shoes or journals). The carbon extracted from these articles will be then mixed with the available carbon from the ashes. Rest assured though, for the outcome of the “Stailas” diamond would be of the same quality as all our memorial diamonds.
