FAQ

1. How do ashes turn into diamonds?

Answer: Turning ashes into diamonds is a remarkable process that transforms your loved one’s cremated remains into a genuine, lab-grown diamond.

Here’s how it works:
Cremation ashes contain carbon — the same element found in natural diamonds. Specialized labs extract this carbon, purify it, and then apply intense heat and pressure, replicating the natural diamond-growing environment. Over several months, this carbon crystalizes into a one-of-a-kind diamond you can wear or cherish forever.

2. How much does an ashes to diamond cost in 2025?

Answer: The cost of turning ashes to diamond in 2025 ranges from $1,400, depending on diamond size, color, and cut. Many top-rated companies offer starter kits and flexible payment plans so you can begin the process now and pay over time.

It’s not just a purchase — it’s a lasting connection.
