The Top 6 Cremation Diamond Companies Turning Ashes into Diamonds

An In-Depth Review of the Top 6 Cremation Diamond Companies

Choosing to transform the ashes of a loved one into a diamond is a significant and deeply personal decision. It is a way to create a lasting, beautiful memorial that can be kept close and cherished forever. This choice requires placing immense trust in the company that will handle this sensitive process. This guide offers a detailed review of the top six cremation diamond companies in the industry. We will explore their history, processes, pricing, and what makes each one unique, providing you with the information needed to select the right partner for creating your memorial diamond.

Part 1: Understanding the Cremation Diamond Process

Before we review the specific companies, it is important to understand the science behind creating a diamond from ashes. A cremation diamond is a real, laboratory-grown diamond. It is physically and chemically identical to a natural diamond mined from the earth. The key difference is its origin: the carbon used to create it comes from the cremated remains of a loved one.

The process involves several key stages:

1. Carbon Verification and Extraction: The journey begins with the cremated ashes. Companies typically require about one pound (or 500 grams) of ashes. The first step in the lab is to analyze the ashes to verify the carbon content. Then, through a series of chemical and heat-based processes, the carbon is separated from all other elements present in the ashes.

2. Purification: To create a high-quality diamond, the extracted carbon must be incredibly pure. The carbon is heated to extreme temperatures in a vacuum environment. This process removes any remaining impurities. The goal is to achieve carbon that is 99.99% pure. This purified carbon is then converted into graphite.

3. Diamond Synthesis (HPHT): The purified graphite is placed into the core of a High-Pressure, High-Temperature (HPHT) press. This machine replicates the conditions deep within the Earth where natural diamonds form. The graphite is subjected to immense pressure (over 800,000 pounds per square inch) and extreme heat (over 2,200 degrees Fahrenheit).

4. Crystallization: Inside the HPHT press, the carbon atoms from the graphite rearrange themselves into the crystal lattice structure of a diamond. This process can take several weeks to many months. The duration of the process determines the final size of the diamond. The unique chemical signature of the individual's ashes, such as the presence of elements like boron, can influence the diamond's final color, often resulting in natural blue or yellow hues.

5. Cutting and Polishing: Once the growth phase is complete, a rough diamond is harvested from the press. This raw stone is then given to a skilled diamond cutter. The cutter analyzes the rough diamond and carefully cuts and polishes facets into it. This final step is what gives the diamond its brilliance, fire, and shape.

Every reputable company will provide a certificate of authenticity, guaranteeing the diamond's origin and detailing its characteristics (the 4Cs: Carat, Color, Cut, and Clarity). Many also offer independent certification from gemological institutes like the GIA or IGI.

Part 3: How to Choose the Right Company for You

Choosing a cremation diamond company is a personal decision. There is no single "best" company for everyone. The right choice depends on your priorities. Consider the following factors:

• Your Budget: Prices vary significantly between companies. Determine your budget first. Companies like EverDear and Heart In Diamond offer more affordable options, while Eterneva and Algordanza are in the premium range.
• Your Desire for Involvement: If you want to be part of the creation journey and receive regular, personal updates, a company like Eterneva is an excellent fit. If you prefer a more straightforward, hands-off process, other companies may be more suitable.
• The Importance of Certification: If independent, third-party verification is crucial for your peace of mind, look for companies that offer GIA or IGI certification. If a company's internal certificate and notarized process are sufficient, a provider like Algordanza might be ideal.
• Company Reputation and History: If you value a long track record and the security of an established business, a pioneer like LifeGem is a strong contender.
• Personal Values: Consider what resonates with you. Is it Swiss precision? A celebratory American spirit? An affordable and accessible approach? Your personal connection to the company's story and mission can be a deciding factor.

Read reviews, speak with representatives from your top choices, and ask detailed questions. A reputable company will be patient, transparent, and compassionate in its communications with you.

FAQs: Cremation Diamonds

How much ash is needed to make a diamond? Most companies require about 1 pound or 500 grams of cremated ashes. Some, like EverDear, can work with as little as 100 grams. The average adult cremation produces 5 to 10 pounds of ashes, so there is more than enough.

How long does it take to turn ashes into a diamond? The process typically takes between 6 to 12 months. The exact timeline depends on the company, the size, and the color of the diamond. Colorless diamonds and larger diamonds require a longer growth period.

Are cremation diamonds real diamonds? Yes, they are 100% real diamonds. They have the same chemical composition (carbon), crystal structure, and physical properties (hardness, brilliance) as diamonds mined from the earth. Gemological labs classify them as laboratory-grown diamonds.

Can you guarantee the final size and color? Companies can target a specific size range and color, but the final result has some natural variation. The unique chemical composition of the ashes can slightly influence the outcome. Reputable companies will explain these potential variations to you.

Can you make a diamond from the ashes of a pet? Yes. The process is the same for pet ashes as it is for human ashes. All the companies listed here offer services to create memorial diamonds for beloved pets.

What happens to the ashes that are not used? All reputable companies will return any unused ashes to the family along with the finished diamond.

Is the process guaranteed? What if something goes wrong? Leading companies have strict quality control and tracking systems. They guarantee the process and the authenticity of the diamond. Ask about their specific policies and guarantees if a diamond does not meet the expected quality standards.
