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.

Saint Diamonds  –  How We Create Lab-Grown Diamonds from Ashes Or Hair – A Process

Phase 1 – Your Welcome Kit

Your journey begins the moment you receive the Saint Diamonds Welcome Kit  –  everything you need to start with confidence and care.

Inside you’ll find:

• A secure, sealed container for the ashes or hair
• Easy-to-follow instructions
• Physical samples of different diamond sizes
• A prepaid return shipping label

💙 A gentle, respectful way to send us what matters most.

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.

Phase 4 – Precision Cutting & Polishing

Once fully grown, each rough diamond is carefully studied. Our master cutters  –  with decades of experience and deep respect for its meaning  –  shape and polish it into the exact cut you’ve chosen, maximizing its fire, brilliance, and beauty.

✨ We don’t simply cut stones; we craft lasting legacies.

Phase 5 – Certification & Personal Touches

Your finished diamond is sent for independent certification, confirming it is 100% authentic and grown from the submitted ashes or hair.

You can also add personal touches such as:

• Laser-engraved messages or initials inside the stone
• Optional color enhancement (green, pink, or red, upon request)

📜 A verified, one-of-a-kind treasure.

Phase 6 – Setting into Jewelry

The final step transforms your diamond into a beautiful piece you can wear every day.

We include:

• Complimentary standard settings (rings, pendants, or earrings) for diamonds 0.75 ct and larger
• Fully custom designs by our in-house jewelers
• The option to incorporate your own jewelry or design

💍 A heartfelt tribute you can keep close to your heart  –  forever.

From Loss to Light

• Honor your loved one with a diamond as unique as their life.
