How do bespoke payment terms work?

We operate on a transparent, two-part collaborative partnership. We require a 50% initial deposit to secure your specific certified diamond and begin crafting in our Auckland studio. The remaining 50% balance is only due upon the successful completion and final quality-check of your ring.

What if the ring is the wrong size after the proposal?

This is incredibly common and entirely stress-free. MOHSTEN provides a complimentary initial ring resizing for all of our signature bespoke engagement rings within the first few months of purchase to guarantee a flawless, comfortable fit.

Lab-grown vs. natural diamonds: What is the difference?

Physically, chemically, and optically, they are completely identical. Lab-grown diamonds allow you to maximize your budget for a larger carat size or clarity, while natural diamonds are finite, Earth-mined treasures curated for their traditional rarity.

How can I maximize my diamond budget?

We recommend prioritizing Cut grade and elongated shapes. Selecting an Excellent or Ideal cut maximizes brilliance and fire, making the stone look visually larger. Shapes like oval, emerald, or marquise cuts also create a larger visual footprint on the hand.

How do I know the final ring will match my concept?
We eliminate all guesswork before touching the precious metal. Once your design concept is locked in, our studio translates it into a hyper-realistic, 3D CAD model, providing a true-to-scale digital preview from every angle with unlimited revisions.

What happens if the settings loosen or the metal dulls?
To protect your investment, every MOHSTEN engagement ring includes three complimentary structural check-ups and professional workshop cleanings throughout its first five years to inspect claws, tighten stones, and restore original brilliance.

How do I know I’m paying for actual sparkle?
Our philosophy is simple: do not pay a premium for microscopic perfection you cannot see in real-world light. We focus on choosing "eye-clean" diamonds with elite cut precision, directing your budget entirely toward the stone's actual fire and beauty.
