About The Company

Heart In Diamond is based out of the UK. However, the company’s reach extends worldwide- with team members in Europe, Asia, Australia and North America.

The company was founded in 2005. It employs skilled engineers who work tirelessly in the lab, producing diamonds from natural carbon found in cremation ashes or locks of hair.

The guiding principles of the company emphasize respect, personal service, quality and affordability.

Heart In Diamond prides itself on using the most eco-friendly, cutting-edge techniques to create quality cremation diamonds without harming the environment.

And their diamonds are authentic enough to stand up to the most discerning of tastes.

The Process

There are several steps to the ordering and creation of your personalized cremation diamond.

All of these steps together take 70-120 days, starting from the time the lab receives your sample until your diamond is delivered.

Ordering Process

First, you will explore various options for the cut, color and carat size of your diamond on the “Create Your Own Diamond” section of the website.

Once this step is complete, you will fill out an online enquiry form and a representative in your area will contact you.

They will email you an official order form and also send you a “Personal Collection Kit”.

Your sample will be sent in a zip-lock carbon collection bag. A half-cup volume of hair or a two-thirds-cup volume of ashes are necessary to grow a diamond.

Sending the ashes

After sending in your official order form, you will be assigned an ID number that allows you to track the process.

When your diamond is ready, it will be hand-delivered to you by courier.

Diamond Creation

Once it arrives in the lab, your sample will be immediately analyzed. They will determine its chemical composition in order to extract the right amount of carbon.

The extracted carbon is then added to a diamond foundation…and slowly a diamond begins to grow.

Diamond Growth

The carbon mixture will then be placed in a High Pressure Temperature machine.

The machine replicates the conditions of natural diamond growth deep in the earth’s crust.

That means temperatures above 2000 °C, and pressure of over 60,000 atmospheres.

Polish and Cut

When it’s finished growing, the diamond is then carefully polished and cut in accordance with the specifications of your order.

They’ll make sure your diamond sparkles both inside and out, just like the person you loved.

Finally, the diamond goes through a tough grading process in order to get a Certificate of Authenticity.


One of the nicest things about this company is their willingness to work with clients on convenient payment plans.

Even better, these plans are available at a 0% interest rate, which is pretty unbeatable.

They offer three plans:

  • A 5% deposit with 6 equal monthly payments
  • A 25% deposit with 12 equal monthly payments
  • A 25% deposit with 24 equal monthly payments

Depending on your plan and the kind of diamond you choose, your monthly payments could be as low as $23 a month.

The overall cost of the diamonds range from $750 for an orange-yellow mini to $17,295 for a 1-carat white diamond.

There are a multitude of pricing options in between those two extremes.

Diamonds come in orange-yellow, yellow-green, deep red and white. Orange-yellow is the most inexpensive, while white is the priciest.

There are also a variety of carat options, ranging from Mini to 2-carat, with a range of seven other options in between.

These prices compare very favorably with other companies, and are significantly less than traditional burial and funeral costs.

Also worth noting: the cost of lab-grown diamonds is 30% less than natural diamonds.

Jewelry Ideas
