A jewelry buyer in Munich asked three factories for a 14k gold wedding band quote. The numbers came back at $48, $52, and $61. She almost signed the cheapest. Then she asked for the alloy sheet. The cheapest quote was 14k "yellow" gold but used a high-copper alloy that darkens over time. The middle quote was standard 585 alloy. The high quote was a nickel-free, EU-compliant alloy for sensitive skin. Three prices, three different products. Bulk gold jewelry manufacturing is not a single material. It is a karat, an alloy, and a spot-price clause, and each one changes the piece. Here is how we spec it, and what to put in your PO.
Karat: what the number means and who wears it
Karat measures the fraction of pure gold in the alloy. 24k is pure. 18k is 75% gold. 14k is 58.5% gold (marked 585). 10k is 41.7% gold (marked 417). The rest is copper, silver, zinc, and sometimes nickel.
| Karat | Gold content | Hardness | Best use |
|---|---|---|---|
| 10k | 41.7% | High | Daily-wear rings, kids' jewelry, budget bridal |
| 14k | 58.5% | Medium-high | Wholesale default, engagement rings, wedding bands |
| 18k | 75% | Medium | High-end boutiques, premium solitaire settings |
14k is the wholesale default for a reason: it is hard enough for daily wear, yellow enough to look like gold, and priced so the boutique can hit a retail margin. 18k sells, but at 30-40% higher material cost. 10k is a value play, mostly in US markets where customers are price-sensitive.
Alloy: the part almost no one asks about
Two rings, both 14k yellow gold, can age very differently depending on the alloy recipe. A high-copper alloy warms the tone but darkens over years of wear. A nickel alloy is bright but causes skin reactions. A nickel-free EU-compliant alloy costs more but passes REACH and skin-contact regulations.
Our standard wholesale 14k yellow alloy is 58.5% gold, 20% copper, 15% silver, 6.5% zinc. It is nickel-free, lead under 90ppm, and passes EU skin-contact standards. Our 14k white uses a rhodium flash over a palladium-white alloy (not nickel), which is why the white tone holds up.
If your factory cannot tell you the alloy recipe, they are buying off-the-shelf grain. That is fine for domestic sales. It is not fine if you export to the EU, where nickel release limits are enforced.
Spot price and the clause that protects you
Gold moves. A quote written today at $1,900/oz and shipped in 45 days is shipping into a market that may be at $1,980/oz. The factory that does not lock the price will call you mid-production. The two standard protections:
- Price lock: We lock the gold price for 30 days from PO sign-off. If spot moves within that window, we absorb it. Beyond 30 days, we re-quote.
- Tolerance band: Some factories build a +/-3% band into the quote. If gold moves within the band, the price holds. Outside it, the buyer and supplier split the difference.
Insist on one of these in writing. A quote with no clause is a quote that will change.
Weight tolerance and why it matters
A 2.8g ring ordered at 1,000 pieces is not 2,800g of gold. It is 2,800g +/- 5%, because casting and polishing remove material unevenly. The industry norm is +/-10%. We hold +/-5% on our gold lines, which means the buyer pays for the gold they actually get, not a generous average.
When you compare quotes, ask what the weight tolerance is. A factory that quotes at 2.8g and ships at 3.1g is quietly charging you 10% more gold than you expected.
Decision guidance by buyer type
Boutique launching gold: Start with 14k yellow. It is the karat that sells. Skip 18k until your 14k hero SKU is proven; the material cost difference is too large for a test run.
EU export buyer: Specify nickel-free, REACH-compliant alloy in the PO. Ask for the alloy sheet and a metal assay certificate. A rejected shipment at customs costs more than the premium alloy ever will.
Wholesale chain: Move to a metal-consignment model. We pre-buy gold grain at a locked price, hold it on your PO, and cast in large trees. You avoid spot volatility and unit cost drops roughly 8-12%.
Frequently Asked Questions
What karat gold is standard for wholesale?
14k (58.5% gold) is the wholesale default for rings and wedding bands. 10k is common in value-priced US markets. 18k is used at the high end. The choice depends on your retail price point and customer expectation.
Is 14k yellow gold nickel-free?
It depends on the alloy. Standard 14k yellow is usually nickel-free by default. 14k white historically used nickel; modern EU-compliant white uses a palladium base under rhodium flash. Always ask for the alloy sheet.
How is gold price locked on a wholesale PO?
Most factories will lock the gold price for 30 days from PO sign-off. If spot moves within that window, the factory absorbs it. Beyond 30 days, the quote is re-issued. Get this clause in writing.
What weight tolerance should I expect on a gold ring order?
Industry norm is +/-10%. Best-practice factories hold +/-5%. Ask for this in the PO; a loose tolerance means you may pay for gold that was never in your ring.
Do you provide an assay certificate on gold orders?
Yes. Every gold order ships with an alloy assay certificate from an independent lab, documenting karat and metal composition. This is required for EU customs and for retail hallmarking.
Key takeaways
- 14k is the wholesale default. 18k is a premium tier; 10k is a value play. Pick the karat that matches your retail price.
- Ask for the alloy sheet. Nickel-free, REACH-compliant alloy costs pennies more and prevents EU customs problems.
- Lock the gold price in the PO. A quote without a lock clause is a quote that will change.
- Hold +/-5% weight tolerance. A +/-10% tolerance is a silent 5% surcharge on every order.
