Stone Guide

At North & Line, we work with exceptional lab-created stones chosen for their beauty, durability and ethical sourcing.

Our collection focuses on premium moissanite and lab grown diamonds, allowing you to choose the stone that best reflects your priorities.


MOISSANITE

Moissanite is a lab-created gemstone renowned for its exceptional brilliance and durability.


WHY WE USE IT

  • Colour grade: D–F
  • Clarity: VVS1
  • Cut: Excellent
  • Hardness: 9.25 on the Mohs scale
  • Ethically created

Moissanite has more fire (rainbow sparkle) than a diamond, creating a bright, luminous look in all lighting conditions.

It is extremely durable, making it perfect for everyday wear.

Centre stones 0.5ct and above can be provided with GRA certification upon request.

Moissanite is an ideal choice for those who value brilliance, longevity and considered luxury.


LAB GROWN DIAMONDS

Lab grown diamonds are chemically, physically and optically identical to mined diamonds.

They are created using advanced technology that replicates the natural diamond growing process — without the environmental or ethical concerns associated with mining.


WHY CHOOSE LAB GROWN

  • Identical composition to natural diamonds
  • Excellent durability (10 on the Mohs scale)
  • Available in a range of carat weights and specifications
  • Lower environmental impact

Lab grown diamonds are graded using the same 4Cs as natural diamonds: cut, colour, clarity and carat weight.


WHAT’S THE DIFFERENCE?


Moissanite

Lab Grown Diamond

More fire (rainbow sparkle)

More traditional white brilliance

Slightly softer (9.25)

Hardest gemstone (10)

More accessible price point

Higher price point

Distinct gemstone

Real diamond (lab-created)


Both options are designed to last a lifetime.


OUR PHILOSOPHY

We believe modern fine jewellery should be:

  • Ethically considered
  • Beautifully made
  • Transparently described
  • Designed for real life

Every North & Line ring is made to order in your chosen metal and stone size — crafted with intention and built to endure.

 

WHY WE SPECIALISE IN MOISSANITE

At North & Line, we intentionally focus on premium moissanite for the majority of our collection.

We believe modern luxury should be intelligent, ethical and beautifully considered.

Moissanite offers exceptional brilliance, outstanding durability and a more accessible price point — without compromising on impact. It allows you to choose a larger carat weight or elevate your setting while maintaining long-term wearability.

For many of our clients, it represents a smarter way to invest in design.

Lab grown diamonds remain available for those who prefer a traditional diamond composition — but moissanite is where contemporary brilliance meets confident luxury.
