Source Natural Diamonds That Perform Beyond The Certificate

Why serious jewellers find diamond sourcing frustrating

A GIA certificate tells you what a diamond grades. It doesn’t tell you how it performs. Most sourcing problems happen in the gap between the two.

Stones that disappoint visually

Fluorescence haze, bow-tie effect in ovals and pears, uneven colour distribution none of these appear on a certificate. You only discover them when it arrives.

Matched pairs that don't match

Sourcing truly matched stones for earrings or layouts same tone, saturation, proportions requires expertise most suppliers either don’t have or won’t invest in.

Short inflated margins.

Multiple intermediaries between mine and jeweller mean markups at every step and no real transparency on what you’re actually paying for or where the stone came from.

Delayed custom execution.

Unusual ratios, calibrated sizes, recut requirements, specific colour intensities standard suppliers can’t accommodate custom specifications without long delays.

Three collections. One standard of eye.

Natural coloured, white, and special-cut diamonds – Explore each collection, or tell us exactly what you need.

Round Brilliants — 0.18ct to 20ct+

All qualities from Triple Excellent (3EX) to Good. Clarities IF to I. GIA, IGI, HRD certified and non-certified options.

Hearts & Arrows Diamonds

Pinpoint optical symmetry verified under magnification. The pinnacle of cutting precision in round brilliants.

Fancy Shapes

Oval, Pear, Marquise, Cushion, Princess, Emerald, Radiant, Asscher, Heart. Guidance on ratio, symmetry, and bow-tie avoidance.

GIA Origin Certification

Mine-to-market traceability. Non-Russian provenance confirmed. For EU and US buyers with sanctions compliance requirements.

Non-Certified Parcels for Manufacturing

Oval, Pear, Marquise, Cushion, Princess, Emerald, Radiant, Asscher, Heart. Guidance on ratio, symmetry, and bow-tie avoidance.

Visual verification beyond what GIA measures

Every stone is inspected under loupe and microscope to assess fluorescence impact, light leakage, and actual visual performance not just paper grades. A D IF with a strong bow-tie is not a stone we’d recommend. A G VS2 that faces up brilliantly, is.

Full colour spectrum

Yellow, Pink, Blue, Green, Violet, Orange, Argyle. From commercially available to ultra-rare intensities.

Full intensity range

Fancy Light through Fancy Vivid and Fancy Deep. Expertise in evaluating how intensity, tone, and saturation interact — and how shape affects colour appearance.

Precision-matched pairs & layouts

Matching coloured stones for earrings, bracelets, and high jewellery sets. Consistent tone, saturation, and proportions across every stone.

Argyle & ultra-rare stones

Argyle pinks, violets, blues. Stones whose rarity is unaffected by the lab-grown market. Natural provenance, certified and documented.

Expertise you cannot read off a price list

Coloured diamond pricing has no fixed benchmark like Rapaport. Evaluation requires understanding how brown or grey undertones affect desirability, how shape choice concentrates or dilutes colour, and how intensity grades at the margins are priced. This is 15 years of Parth Shah’s specialisation.

Heritage cuts

Old Mine Cuts, Old European Cuts, Rose Cuts. Valued for character and period authenticity, not modern proportion standards.

Geometric & designer cuts

Half-moons, Trapezoids, Baguettes, Shields, Hexagons, Cadillacs, Kites, Epaulets, Trilliants, Briolettes and more.

Calibrated sets for designer jewellery

Precision-matched in symmetry and exact measurements for seamless integration into bespoke and high jewellery designs.

Matching complexity most suppliers won't attempt

Special cuts don’t follow standard proportion tables. Matching a set of half-moons or calibrating trapezoids to exact measurements requires judgement that no certificate provides. We specialise in this complexity because it’s where most suppliers give up.

About Raremonds

Every middleman adds a percentage, inflating your final cost. By the time a stone reaches your bench, you’ve paid premium margins that eat into your profits.

Finding a single stone is easy; sourcing 20 perfectly matched parcels or unique accent layouts for custom high-jewelry takes weeks of frustrating back-and-forth. Many online listings don’t actually own the stones they list. You pitch a diamond to a client, only to find out it was sold days ago by someone else.

What separates us
from every other supplier

Not marketing claims. Specific, verifiable things that matter to a trade buyer who has been let down before.

Expert Guidance

From sourcing the finest stones to bringing them unscathed to the client, we are trusted guides in every facet of the industry, ensuring our clients receive tailored service with every transaction.

Exclusive Collection

Explore and choose from curated collections that feature gems that are a testament to luxury. Our limited-edition collections showcase exquisite diamonds that are the epitome of sophistication.

Ethically sourced. Fully traceable.

GIA Origin Certification available. Non-Russian provenance confirmed. For buyers in the EU and USA navigating diamond sanctions compliance, we provide the traceability documentation your clients and regulators require.

What the trade says about working with us.

From jewellers and designers who have sourced through Raremonds across multiple markets.

Parth’s ability to source and match coloured diamonds at the right prices with full transparency at every stage is unlike any other supplier I’ve worked with. He’s not selling diamonds, he’s solving problems.

— Fine Jeweller, New York, USA

Raremonds custom layout was precise to the last stone, with consistent tone and matching saturation delivered right on schedule. They are now our absolute go-to for anything that is technically complex.

— Jewellery Designer, Sydney, Australia

What sets Raremonds apart is that Parth looks at every stone himself. I’ve received diamonds from other suppliers that matched the cert but not my expectations. That doesn’t happen here.

— Independent Jeweller, London, UK

I come to Raremonds for coloured diamonds specifically. The depth of knowledge on colour behaviour, pricing, and matching is something I haven’t found anywhere else at this price level.

No minimum. We work with everything from a single stone for a bespoke commission to large calibrated parcels for jewellery manufacturing. Tell us your requirement and we'll work with it, whatever the scale.

For standard requirements we respond with options within 24–48 hours. Complex matching, bespoke recut specifications, or hard-to-find colour intensities may take 3–5 business days depending on availability in our global network. We'll always give you a timeline upfront.

Yes. We supply calibrated, non-certified melee and parcel lots for jewellery manufacturing — with consistent colour, clarity, and size grading applied to your specified tolerances. Each parcel goes through our in-house QC process before dispatch.

Yes. GIA Origin Certification is available for stones where EU and US diamond sanction compliance documentation is required. We can provide origin traceability documentation for your compliance needs. Speak to us about your specific requirements and jurisdiction.

We're listed on Rapnet and Nivoda — the diamond trade's two principal sourcing platforms — where our standing is independently verifiable. We hold partnerships with GIA, IGI, and HRD Antwerp. We're also happy to provide references from existing clients in your market on request.

Both. Our work is overwhelmingly with the trade — jewellers, designers, manufacturers. But we also work directly with private clients on bespoke jewellery commissions, offering direct access to rare diamonds at trade pricing without retail intermediaries. If you're a private client, mention this in your enquiry and we'll route you to our bespoke jewellery service.

A listing platform shows you what's available. We tell you what's actually worth buying. Every stone we recommend has been visually evaluated — beyond the certificate — for fluorescence impact, colour behaviour, light performance, and make quality. We also handle matching, bespoke cutting, and complex specifications that no platform can provide.

A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous.

When it comes to diamond grading laboratories, there is only one in the jewelry business that truly matters. That laboratory is the GIA (Gemological Institute of America) or more commonly known as GIA. GIA invented most of the systems in use today to grade the 4 C’s of diamonds, and they are completely unbiased in their grading process. This is why they are the most widely respected and only trusted source when one wants to know exactly the quality of a diamond. Those in the diamond or jewelry business submit their product to GIA in order to obtain a certificate that outlines all of the important attributes pertaining to a particular diamond.

Only one in every 10,000 diamonds possesses natural colour and is referred to as a coloured diamond. For this reason, coloured diamonds are purchased almost exclusively for the intensity and distribution of the diamond's colour. When buying a coloured diamond, it is imperative that you look out for the 4 C's of the Diamond namely - Cut, Colour, Clarity & Carat. Also, verify that the seller has the Diamonds which are approved by GIA.

Tell us what you need. We'll handle the rest.

No minimum order. Single stones to large programmes. Share your requirement shape, size, quality, quantity, intended use and we’ll respond within 24 hours with options and indicative pricing.

The thinking behind how we judge a stone

Written for buyers who want to understand what sits beneath a grade not just read one. A few pieces worth your time.

Diamonds 101

Why a GIA Certificate Alone Is Not Enough

The grade tells you what a diamond is on paper. It says nothing about how it faces up. Where the gap lies and why it matters to your client.

For Trade Buyers

The BowTie Effect in Oval and Pear Diamonds

A heavy bow-tie does not cost you a diamond. It costs you a remake, a returned piece, a client who quietly stops reordering.

The Natural Case

Natural Diamonds vs Lab Grown Diamonds

Where value holds, where it doesn’t, and why rarity still belongs to the earth. This is a clear-eyed, essential comparison built explicitly for trade buyers and their private diamond clients.
