New Zealand has a well-established jewellery market, with Auckland, Wellington, and Christchurch home to specialist jewellers, diamond wholesalers, and bespoke jewellery businesses. Buyers can source certified natural diamonds for engagement rings, fine jewellery, high jewellery, and custom designs.
For jewellers, designers, collectors, and private clients, choosing the right supplier involves more than comparing price. Certification, sourcing, provenance, diamond quality, matching capabilities, and bespoke services are all important.

Why Choose Raremonds for Natural Diamonds in New Zealand?
New Zealand buyers have access to established local jewellers and diamond businesses, but sourcing a truly exceptional natural diamond can become more complicated when the requirement involves rare colour, unusual cuts, exact measurements, matched pairs, or bespoke high-jewellery layouts.
Raremonds focuses specifically on these specialist requirements.
15+ Years of Natural Coloured Diamond Expertise
Raremonds brings more than 15 years of expertise in natural fancy coloured diamonds, led by Parth Shah.
His experience in natural coloured diamonds and participation in major international diamond trade shows gives clients access to specialist knowledge when sourcing rare and unusual stones.
This is particularly important with coloured diamonds because two stones with similar grades can have very different visual appeal depending on colour distribution, saturation, tone, undertones, and shape.
A Full Spectrum of Natural Coloured Diamonds
Raremonds specializes in natural coloured diamonds including:
- Yellow
- Pink
- Blue
- Green
- Violet
- Orange
- Argyle
The brand works across intensity ranges including Fancy Light, Fancy, Fancy Vivid, and Fancy Deep, depending on availability.
Diamond Evaluation Beyond the Certificate
A laboratory report provides essential information about a diamond, but visual inspection can reveal additional characteristics that influence how a stone looks.
Raremonds personally evaluates diamonds under loupe and microscope, checking details such as:
- Fluorescence haze
- Bow-tie effect
- Uneven colour distribution
- Saturation consistency
- Overall visual performance
This specialist inspection helps clients evaluate diamonds beyond simply reading a grading report.
Precision-Matched Natural Diamonds
For jewellery designers, finding one natural diamond is often easier than finding several diamonds that look consistent together.
Raremonds specializes in precision-matched pairs and layouts, considering:
- Colour
- Tone
- Saturation
- Dimensions
- Proportions
- Overall appearance
These services are particularly useful for earrings, bracelets, rings, multi-stone designs, and high-jewellery projects.
Where appropriate, the company can also explore recut-to-match options to improve consistency between stones.
Special-Cut and Designer Diamonds
Raremonds sources special cuts that may be difficult to find through standard diamond inventories.
These include:
- Old Mine Cuts
- Old European Cuts
- Rose Cuts
- Half-Moons
- Trapezoids
- Baguettes
- Shields
- Hexagons
- Cadillacs
- Kites
- Epaulets
- Trilliants
- Briolettes
For designers working with exact millimeter measurements or unconventional jewellery layouts, specialist sourcing can be particularly valuable.
Argyle and Ultra-Rare Diamonds
Australia and New Zealand have a strong connection to the history of Argyle diamonds, particularly rare pink diamonds.
Raremonds specializes in Argyle and ultra-rare natural diamonds, providing access to exceptional stones when available, along with provenance-focused documentation where applicable.
Ethical and Traceable Sourcing
For buyers in New Zealand and the wider Asia-Pacific market, responsible sourcing and provenance can be important considerations.
Raremonds offers GIA Origin Certification where available and non-Russian provenance documentation for clients who require additional sourcing and compliance information.
Bespoke Diamond Sourcing
A specific jewellery design may require a diamond that cannot be found in standard online inventory.
Raremonds can work around requirements for:
- Exact millimeter measurements
- Specific colour
- Particular shape
- Carat range
- Intensity
- Saturation
- Matching stones
- Specific proportions
The company provides custom sourcing, custom cutting, precision matching, calibrated layouts, and made-to-spec diamond programs.
