For independent jewelers, custom designers, and retail buyers across the United States, finding a dependable loose diamond source is one of the most critical decisions in running your business. The right supplier affects your margins, the range you can offer clients, and your ability to fulfill custom requests without delays or compromise.
The U.S. jewelry market is competitive. Clients are more informed than ever, design trends are moving faster, and the pressure to offer distinctive inventory at fair prices is real. Sourcing directly from a manufacturer — rather than through domestic distributors or local brokers — is one of the most effective ways American jewelers are responding to that pressure.
Gems Diamonds by Shikha is a manufacturer, exporter, and direct supplier of fine quality loose diamonds, gemstones, and finished components based in India. We supply trade clients across the U.S. with everything from raw rough diamonds and rose cut diamonds to specialty cuts, colored gemstones, and custom-made cabochons and carvings — all at manufacturer-level pricing, without the markup of a middleman.
Why U.S. Jewelers Are Turning to Direct International Suppliers
The traditional sourcing model — buying from domestic distributors who purchase from overseas manufacturers — made sense when global trade was harder to navigate. That's no longer the case. Today, U.S. jewelers can work directly with overseas manufacturers through straightforward digital communication, international shipping infrastructure, and verified certifications that hold up to the same standards as domestically sourced stones.
What direct sourcing from a manufacturer like Gems Diamonds by Shikha means for a U.S. buyer:
• Manufacturer-level pricing — no distributor margin layered on top
• Access to a far wider inventory than any domestic wholesaler carries
• The ability to request custom cuts, shapes, and sizes not available through standard channels
• Direct communication with the people making the product, not a sales intermediary
• Consistent supply relationships built around your specific inventory needs
For jewelers in major U.S. markets — New York, Los Angeles, Dallas, Chicago, Miami — and independent studios across the country, this shift to direct sourcing has become a genuine competitive advantage.
Where Our Diamonds and Gemstones Come From
Our manufacturing operates across two of India's most important trade centers, each chosen for what it does best.
Jaipur — The Heart of the Global Gemstone Industry. Our gemstone production facility is in Jaipur, which processes a significant share of the world's colored gemstones. The artisan knowledge base here — for cutting, carving, polishing, and beading — has been built over generations and simply cannot be replicated quickly elsewhere. Every colored gemstone product we supply is produced in this environment.
Surat — The Diamond Capital of the World. Our raw diamond and rose cut diamond processing happens in our own unit in Surat, which is responsible for cutting and polishing the vast majority of the world's diamonds. Having our own facility there means quality is controlled at the source — not assessed after the fact by a third party.
When a U.S. jeweler sources through us, they're buying directly from these two manufacturing centers — not from a broker who bought from a distributor who bought from the source.
Our Full Product Range for U.S. Trade Buyers

Two Areas Where We Go Beyond Standard Supply
Custom Cabochons — Any Shape, Any Size, Any Stone
Our speciality is cutting faceted or smooth cabochons in any customised shape and size, in any gemstone or diamond. This is not a catalog selection — it is production to your specification. U.S. designers and jewelers who need consistent custom shapes for recurring collections, or who want exclusive forms not available through standard wholesalers, should get in touch directly to discuss requirements. We handle both one-off pieces and ongoing production runs.
Handmade Gemstone Carvings — Custom Design and Shape
Our Jaipur artisans produce handmade gemstone carvings to custom design and shape. For U.S. designers working in high-end or collector markets, handmade carvings represent a category that is genuinely difficult to source consistently at this level of craft. We can work from reference designs or brief descriptions. Browse our carvings section for examples of what's possible — and reach out when you're ready to discuss a custom commission.
How U.S. Jewelers Typically Work with Us
Most U.S.-based trade clients come to us through one of three routes: a recommendation from another jeweler already in our network, a search for a specific product they haven't been able to source domestically, or a need for custom work that local or domestic suppliers aren't equipped to handle.
The starting point is almost always a conversation about what you need — stone types, cuts, sizes, quantities, lead time requirements. From there, most new clients place a sample order to assess quality and consistency before committing to a larger supply relationship. That's the right approach, and we fully support it.
Once a working relationship is established, the process is straightforward. You specify requirements, we manufacture or source to those specifications, and delivery is handled through our established international shipping and documentation process. All relevant certifications and grading documentation are provided as standard.
What Sets Direct Manufacturer Sourcing Apart for the U.S. Market
Pricing: Buying directly from the manufacturer removes distributor and broker margins. For U.S. jewelers competing on price or trying to protect margins on custom work, the difference is meaningful — typically 20 to 40 percent compared to buying through domestic wholesale channels.
Range: No domestic distributor carries our full range. Salt and pepper diamonds, rose cuts, raw rough diamonds, custom-cut cabochons, handmade carvings, gemstone briolettes, lab grown diamonds across multiple specifications — this depth of inventory is only accessible by going to the manufacturer directly.
Customization: U.S. designers who want something specific — a particular cabochon shape, a custom carving design, a consistent run of an unusual diamond cut — can only get that by working with a manufacturer. Distributors can't produce to order. We can.
Reliability: Our supply relationships are built on repeat business, not single transactions. U.S. clients who establish a working relationship with us gain a consistent source they can plan inventory around, rather than piecing together supply from multiple domestic vendors.
