Why Choose Raremonds for Natural Diamonds in Singapore?
Singapore has a sophisticated jewellery market with several established natural-diamond specialists. However, requirements become much more complex when a client needs a rare coloured diamond, unusual cut, precisely matched pair, exact millimeter dimensions, or a bespoke high-jewellery layout.
Raremonds is built around 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 the natural coloured diamond market and participation in major global trade shows provides clients with specialist knowledge when sourcing rare and exceptional stones.
This is particularly important for coloured diamonds because colour, tone, saturation, undertones, shape, rarity, and origin can all affect a stone’s appearance and desirability.
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 such as Fancy Light, Fancy, Fancy Vivid, and Fancy Deep, depending on availability.
Evaluation Beyond the Certificate
A diamond grading report provides essential information, but visual characteristics also matter when selecting an exceptional stone.
Raremonds inspects diamonds under loupe and microscope, evaluating:
- Fluorescence haze
- Bow-tie effect
- Uneven colour distribution
- Saturation consistency
- Overall visual performance
This additional inspection helps clients evaluate the diamond beyond basic certificate specifications.
Precision-Matched Natural Diamonds
Finding one natural diamond is different from sourcing several diamonds that look consistent together.
Raremonds specializes in precision-matched pairs and layouts for:
- Earrings
- Bracelets
- Rings
- Multi-stone jewellery
- High-jewellery designs
Matching considers colour, saturation, tone, dimensions, proportions, and overall appearance. Where appropriate, recut-to-match capabilities can help achieve greater consistency.
Special-Cut and Designer Diamonds
Raremonds specializes in sourcing distinctive cuts that may not be readily available through conventional diamond inventories.
These include:
- Old Mine Cuts
- Old European Cuts
- Rose Cuts
- Half-Moons
- Trapezoids
- Baguettes
- Shields
- Hexagons
- Cadillacs
- Kites
- Epaulets
- Trilliants
- Briolettes
For jewellery designers working with exact measurements or unusual layouts, specialist sourcing can be especially valuable.
Argyle and Ultra-Rare Diamonds
Raremonds also specializes in Argyle and ultra-rare natural diamonds.
For collectors and high-jewellery designers, rare natural coloured stones with documented provenance can provide a distinctive option for exceptional jewellery projects.
Ethical and Traceable Sourcing
Raremonds places strong emphasis on sourcing and traceability.
GIA Origin Certification is available where applicable, along with non-Russian provenance documentation for clients who require additional information for compliance requirements in markets such as Singapore, the EU, and the USA.
Bespoke Diamond Sourcing
Standard diamond inventory cannot always meet a designer’s exact requirements.
A client may need a particular:
- Colour
- Shape
- Carat range
- Intensity
- Saturation
- Millimeter measurement
- Proportion
- Matching combination
Raremonds provides custom sourcing, precision matching, custom cutting, calibrated layouts, and made-to-spec diamond programs built around individual design requirements.
