Why Choose Raremonds for Natural Diamonds in Vietnam?

Vietnam’s diamond market offers several established jewellery companies and diamond suppliers, but requirements become considerably more complex when a client needs a rare coloured diamond, unusual cut, precision-matched pair, specific millimeter dimensions, or a bespoke high-jewellery layout.

Raremonds specializes in exactly these 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 international trade shows provides clients with specialist knowledge when sourcing unusual and rare natural diamonds.

Natural Coloured Diamonds Across the Full Spectrum

Raremonds specializes in natural coloured diamonds including:

  • Yellow
  • Pink
  • Blue
  • Green
  • Violet
  • Orange
  • Argyle

The company works across intensity ranges including Fancy Light, Fancy, Fancy Vivid, and Fancy Deep, depending on stone availability.

For coloured diamonds, factors such as colour distribution, saturation, tone, undertones, shape, rarity, and origin can significantly influence appearance and desirability. Specialist evaluation is therefore particularly important.

Evaluation Beyond the Certificate

A grading report provides essential information about a diamond, but specialist inspection can reveal additional visual characteristics.

Raremonds inspects diamonds under loupe and microscope, assessing:

  • Fluorescence haze
  • Bow-tie effect
  • Uneven colour distribution
  • Saturation consistency
  • Overall visual performance

This helps clients evaluate diamonds beyond simply comparing certificate specifications.

Precision Matching for Jewellery

Finding one beautiful natural diamond is very different from sourcing a group of diamonds that look consistent together.

Raremonds specializes in precision-matched pairs and layouts, considering:

  • Colour
  • Tone
  • Saturation
  • Dimensions
  • Proportions
  • Overall appearance

This is particularly valuable for earrings, bracelets, rings, multi-stone jewellery, and high-jewellery designs.

Where required, recut-to-match capabilities can help improve symmetry and consistency.

Special-Cut and Designer Diamonds

Raremonds sources special cuts that can be difficult to find through conventional diamond inventories, including:

  • Old Mine Cuts
  • Old European Cuts
  • Rose Cuts
  • Half-Moons
  • Trapezoids
  • Baguettes
  • Shields
  • Hexagons
  • Cadillacs
  • Kites
  • Epaulets
  • Trilliants
  • Briolettes

These stones can be particularly valuable for designers developing distinctive or highly technical jewellery layouts.

Argyle and Ultra-Rare Diamonds

Raremonds also specializes in Argyle and ultra-rare natural diamonds.

For collectors and high-jewellery designers, access to rare natural stones with documented provenance can be especially important when developing exceptional jewellery pieces.

Ethical and Traceable Sourcing

Provenance and sourcing documentation are increasingly important for international diamond buyers.

Raremonds provides GIA Origin Certification where available and non-Russian provenance documentation for clients requiring additional compliance information for markets such as the EU and USA.

This gives buyers greater transparency around natural diamond sourcing.

Bespoke Diamond Sourcing

Standard inventory does not always satisfy a jewellery designer’s exact requirements.

A project may require:

  • Specific colour
  • Exact millimeter measurements
  • Particular shape
  • Specific intensity
  • Matching stones
  • Precise proportions
  • Defined carat range
  • Calibrated layouts

Raremonds provides custom sourcing, matching, custom cutting, calibrated layouts, and made-to-spec diamond programs based on these requirements.

Bespoke Jewellery Manufacturing

Raremonds also provides bespoke jewellery manufacturing for private clients, collectors, boutique brands, designers, and trade professionals.

Services include:

  • Custom jewellery manufacturing
  • High-jewellery production
  • White-label manufacturing
  • Design-to-production execution
  • Bespoke diamond jewellery

This allows international clients to work with one specialist partner for natural diamond sourcing and jewellery production.
