Turning Ashes Into Diamonds

It seems almost like a miracle, right? All of a sudden, your loved one’s human body is transformed into a beautiful diamond ring or pair of diamond earrings.

Your loved one’s ashes go through a distinct and delicate process using the following steps:

Purifying the Carbon

First, the body’s carbon must be isolated and purified. During the cremation process, just about 96% of the carbon is burned off, but the remaining carbon must be purified.

Once complete, the isolated carbon is a powdery substance that must then be refined to create pure carbon. The process can take weeks and is how the diamond starts.Diamond Growth

In order to ‘grow’ the diamond, there must be heat and pressure.

With the help of experienced scientists and top-quality machinery, the purified carbon sits in 2,500 degrees Fahrenheit temperatures and under 850,000 pounds per square inch of pressure. This is when the diamond grows into a raw and unique diamond.

The process starts slow and the longer the diamond is allowed to sit, the larger it grows.

Cutting the Diamond

At this point, you get to choose the diamond’s cut. A few options include:

  • Round
  • Emerald
  • Radiant
  • Pear
  • Princess

The cut determines the diamond’s shine and brilliance, just like you would buy a diamond in the store. You can see the various cuts each company offers right on their website.

Diamond Coloring

If you prefer to personalize the diamond in your loved one’s favorite color or you have a preference, you can choose the color in this stage.

You can opt for a clear diamond or choose a variety of colors during the irritation treatment. Because each diamond is unique, no two diamonds will look identical, no matter their similarities.

Diamond Grading

Once complete, each diamond receives a grading report, much like you receive when you buy an engagement ring. The grading details the most important Cs – cut, clarity, color, and carat and can be used for your appraisal and valuation when insuring the diamond.

Eterneva wasn’t even the first company to start the process – there have been many others already taking part in the process of creating cremation diamonds, which is a very real process.

The grading report includes details on the cut, carat, color, and clarity of the diamond. You receive a copy of the report to keep for your own records.
