Introduction  –  How are diamonds cut

You’ve seen the sparkle. You’ve felt the emotion when someone opens that little box.

But have you ever wondered how a dull, greasy-looking pebble turns into a gem that literally bends light and stops hearts?

That transformation is called the diamond cutting process  –  one of the most skillful, high-stakes crafts on earth. One tiny mistake can destroy tens of thousands of dollars in seconds.

Whether it’s a mined diamond or a cutting-edge lab-grown diamond (like the ones we create at Saint Diamonds), every flawless stone you admire went through the same intense journey.

Today, I’m pulling back the curtain  –  step by step  –  so you can choose your next diamond with total confidence.

How Are Diamonds Cut – The 5 Traditional Stages of the Diamond Cutting Process in 2025

Even with modern technology, master cutters follow these five sacred stages:

  1. Planning  –  4K 3D scanners and AI software map the rough diamond’s inclusions and crystal structure. The goal? Maximize carat weight while achieving perfect proportions.
  2. Cleaving or Sawing  –  A laser or diamond-coated saw splits the stone along its grain. This is the point of no return.
  3. Bruting  –  The diamond is rounded into a cone shape by spinning it against another diamond. Old-school cutters did this by hand; today it’s robotic precision.
  4. Blocking  –  Eight main facets on the crown and eight on the pavilion are created, plus the table and culet  –  18 facets total.
  5. Brillianteering (Polishing)  –  The final 40 facets are added and polished to mirror perfection. This is where fire and scintillation are born.

A single 1-carat round brilliant can take 12 – 30 hours of polishing alone.

Phase 2 – Extracting the Carbon

When your package arrives, we carefully isolate the carbon from the cremated remains or hair.

Even though only a small amount of carbon is present in ashes, our specialists use a precise, gentle process to purify it  –  this pure carbon is the foundation of your loved one’s diamond.

🧬 This is where science begins turning memories into something eternal.

Phase 3 – Growing the Diamond

We recreate the extreme heat and pressure found deep inside the Earth.

Your purified carbon is placed with a tiny diamond seed, and over several months it slowly crystallizes, layer by layer, into a genuine diamond grown from your loved one.

💎 Every diamond is completely unique  –  just like the person it memorializes.
