We work exclusively with lab-grown diamonds, not because they are “new,” but because they are measurable, consistent, and controllable.

Every Leonids diamond meets the same internal standard:

• Color: D–E
• Clarity: VVS
• Certification: IGI
  

Every Leonids diamond is paired with an IGI certification, documenting its characteristics and origin.

Lab-grown diamonds allow us to control quality at scale. Instead of compromising clarity or color to hit price points, we let customers allocate budget where it matters most: size, cut, and visual presence.

This is the foundation of our Carat Freedom philosophy.

Same optical properties. Higher clarity. Clear documentation.

Precious metals carry impact long after they leave the workshop. That’s why material choice matters as much as craftsmanship.

We work with:

• 14K gold for durability and daily resilience
  
• 18K gold for richer tone and refined weight
  

All gold used is solid, never plated or filled.
We primarily use recycled gold, which meets the same metallurgical standards while reducing environmental impact.

Platinum is chosen when permanence matters.

It is:

• Naturally white
• Exceptionally dense
• Resistant to metal loss over time
  

Unlike white gold, platinum does not rely on surface coatings. When scratched, it displaces rather than wears away, keeping prongs and settings secure for decades.

This makes it ideal for engagement rings and pieces designed for long-term wear.

Silver is often treated as a lower tier material. We don’t agree.

Our 925 sterling silver is selected and engineered specifically for fine jewelry applications, not mass-market accessories.

We evaluate silver pieces for:

• Structural thickness
• Balance on the body
• Long-term setting security

Silver requires more engineering discipline than gold, not less. When done correctly, it becomes a material that allows everyday diamond jewelry without excess weight or cost.
