The Saint Diamonds team have carefully reviewed the information available online about the Eterneva company, and we are more than happy to share that with you today!
According to the website, Eterneva celebrates special people & pets by turning ashes or hair into diamonds. Their experiential Diamond Journey helps grievers heal.
We have explored the most popular questions about Eterneva, and we have the answers ready for you. Now let’s begin!
1. Can Eterneva Make Diamonds from Hair?
Yes, Eterneva can create diamonds using either human hair or pet fur. The process mirrors that of turning ashes into diamonds:
- Carbon extraction: Hair is pulverized, purified (removing impurities), and turned into carbon powder in a graphite crucible
- Diamond formation: The purified carbon is placed in a high-pressure, high-temperature (HPHT) or lab-grown system that mimics Earth’s mantle conditions to crystallize the carbon into diamond
- Cutting and polishing: The resulting raw diamond is inspected for inclusions, precisely cut and polished by master cutters
- Quality: These lab-grown diamonds are chemically and visually equivalent to mined diamonds and are graded with the same grading systems, as authorities no longer differentiate between synthetic and natural diamonds
2. Who Owns Eterneva?
Eterneva was co-founded by Adelle Archer and Garrett Ozar in 2016 (or early 2017) in Austin, Texas. Both serve as Co‑CEOs today, with Garrett taking on Chief Strategy responsibilities.
Background & Origin:
- Adelle Archer created the first diamond in memory of her mentor, Tracey Kaufman, who passed away from pancreatic cancer. This deeply personal experience inspired the foundation of the company.
- Garrett Ozar joined as co-founder—Adelle Archer had previously worked with him at BigCommerce.
- Their “why”: Adelle Archer envisioned a more meaningful, joyful way to memorialize lives than traditional funeral rituals.
3. Are Eterneva Diamonds Real?
Absolutely — Eterneva produces real, authentic diamonds, grown from carbon extracted from ashes or hair. These memorial diamonds are not novelty items — they follow the same physical, chemical, and optical properties as natural diamonds.
Certification and Traceability:
- Each diamond comes with GIA or IGI certification, providing industry-standard grading for carat, cut, color, and clarity.
- Eterneva also offers its own memorial-specific grading report, indicating that the diamond contains personal carbon (making it traceable).
- They guarantee minimum clarity of SI2 or better and offer free regrowth if standards aren’t met.
4. How Long Does It Take to Make a Diamond Out Of Someone’s Ashes?
The timeline throughout the entire process typically ranges between 7 to 12 months:
- Carbon purification: Takes up to 2 months.
- Diamond growth: Up to 3 months.
- Cutting and polishing: Up to 1 month.
- Additional time for coloration, settings, and shipping: coloration (1–3 months depending on color), setting (~1 month), and hand‑delivery or FedEx shipping adds time.
- Overall, the journey commonly spans 7–12 months, with larger or colored diamonds taking longer.
5. How Do They Compress Ashes Into a Diamond?
Eterneva uses cutting-edge lab technology to replicate natural diamond formation:
- HPHT (High Pressure/High Temperature): Mimics Earth’s mantle using up to ~825,000 psi and ~2,500 °F (or pressures of 6–8 GPa and 2,200–2,500 °C).
- Growth cell with diamond seed: Carbon is placed with a seed crystal and metal alloy; under extreme heat and pressure, carbon crystallizes into diamond starting at the seed.
- CVD (Chemical Vapor Deposition): Eterneva also developed a proprietary method to use CVD for memorial diamonds—converting carbon to methane gas for layer-by-layer growth in CVD machines, customized for single orders.
After growth, rigorous inspection, hand‑cutting, polishing, optional coloration, grading, engraving, and possible jewelry setting follow.
6. How Much Of Someone’s Ashes Do You Need To Make a Diamond?
- Ashes: About ½ cup of cremated remains—most adult ashes yield 8–10 cups, so half a cup is enough.
7. How Much Does a Diamond From Eterneva Cost?
Pricing varies significantly based on size and color:
- Starting cost: Around $2,999 to $3,499 for small (.1 ct) colorless, blue, or yellow diamonds.
- Common sizes:
- 0.5 ct: ~$7,699
- 1 ct: ~$15,000
- 2 ct: ~$24,500
- 3 ct: ~$42,000
- Upper range: Custom larger diamonds can cost up to $75,000.
- Final pricing depends on the chosen carat, color, and complexity of the project.
