Why Choose Raremonds for Natural Diamonds in Spain?
Spain offers buyers access to a number of established diamond distributors and luxury jewellery houses. However, requirements become more complex when a client needs a rare coloured diamond, an unusual cut, perfectly matched stones, or diamonds manufactured to exact dimensions.
This is where Raremonds takes a specialist approach.
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 the natural coloured diamond market and participation in major international trade shows provides specialist insight into sourcing rare and exceptional stones.
A Full Spectrum of Natural Coloured Diamonds
Raremonds specializes in a broad range of natural coloured diamonds, including:
- Yellow
- Pink
- Blue
- Green
- Violet
- Orange
- Argyle
Diamonds can be sourced across intensity ranges such as Fancy Light, Fancy, Fancy Vivid, and Fancy Deep, depending on availability.
Evaluation Beyond the Certificate
Certification is important, but a grading report does not capture every visual characteristic that affects a diamond’s appearance.
Raremonds personally inspects stones under loupe and microscope, evaluating:
- Fluorescence haze
- Bow-tie effect
- Uneven colour distribution
- Saturation consistency
- Overall visual performance
This additional level of inspection helps clients make better-informed purchasing decisions.
Precision-Matched Natural Diamonds
For jewellery designers, finding one diamond is only the beginning. Creating a consistent pair or multi-stone layout can be significantly more difficult.
Raremonds specializes in matching diamonds for:
- Earrings
- Bracelets
- Rings
- Multi-stone jewellery
- High-jewellery layouts
The process considers colour, saturation, tone, dimensions, proportions, and overall appearance. Recut-to-match capabilities can also be used where appropriate.
Special-Cut and Designer Diamonds
Raremonds sources distinctive cuts that may not be readily available through standard inventory, including:
- Old Mine Cuts
- Old European Cuts
- Rose Cuts
- Half-Moons
- Trapezoids
- Baguettes
- Shields
- Hexagons
- Cadillacs
- Kites
- Epaulets
- Trilliants
- Briolettes
These diamonds are particularly useful for designers working with architectural jewellery, vintage-inspired designs, or precise high-jewellery layouts.
Ethical and Traceable Sourcing
For European buyers, provenance and compliance are increasingly important considerations.
Raremonds provides GIA Origin Certification where available and non-Russian provenance documentation for clients requiring additional sourcing and compliance information.
This creates greater transparency around the natural diamonds being sourced.
Bespoke Diamond Sourcing
Standard online inventory cannot always satisfy a designer’s exact requirements. A project may require a specific:
- Colour
- Shape
- Carat weight
- Intensity
- Millimeter measurement
- Saturation
- Proportion
- Matching combination
Raremonds offers custom sourcing, matching, custom cutting, calibrated layouts, and made-to-spec diamond programs designed around these requirements.
Bespoke Jewellery Manufacturing
Raremonds also provides bespoke jewellery manufacturing for private collectors, jewellery designers, boutique trade professionals, and luxury brands.
Services include:
- Custom jewellery manufacturing
- High-jewellery production
- White-label jewellery
- Design-to-production execution
- Bespoke diamond jewellery
This makes Raremonds a suitable partner for clients looking for both specialist diamonds and finished jewellery production.
