This guide explains how the gold price in USA is calculated, which karat to buy, and where to buy gold in New York and Los Angeles. First: there is no separate American gold price. Gold trades at one global price per troy ounce in US dollars — and because the United States prices gold in dollars, the American price is that global spot price. When the price moves, it is because the global gold market moved.
How the gold price in USA is calculated
The calculation starts with the global spot price: gold is traded worldwide at one price per troy ounce in US dollars. One troy ounce is 31.1034768 grams — not an ordinary ounce. Divide the spot price by 31.1034768 for the price of one gram of pure (24K) gold in dollars.
The karat fraction gives the price for lower karats: 14K gold is 14/24 pure, so its price per gram is 14/24 of the 24K price; 18K is 18/24. That is the whole calculation — spot price, divided by grams per troy ounce, multiplied by the karat fraction.
That is how the Gold Price in USA page on ToolZana works: it takes the live USD spot gold price from AlyawmGold and shows the price per gram, per troy ounce and per kilogram in USD, for every karat. The prices are the raw spot rate before dealer commission and making charges.
A worked example, with round numbers that are hypothetical, not today’s prices: suppose the spot price were $4,000 per troy ounce. One gram of pure 24K gold would then be about $128.60, and one gram of 14K gold about $75.02 — so a 10-gram 14K ring would hold about $750 of metal before making charges. The same maths works at any live price.
The dollar and the units gold is quoted in
Because the United States prices gold in dollars, there is no exchange-rate effect on the gold price in USA. In countries that price gold in a local currency, a weaker currency pushes the local gold price up even when the world price is flat. In the US, the dollar price moves only with the gold market itself.
In the US, gold is quoted per gram and per troy ounce in USD. The troy ounce (31.1034768 grams) is the international standard for pricing gold, and American dealers quote bullion — bars and coins — per troy ounce. Jewellery is usually quoted per gram, and the price tag on a ring or chain is the total price of the finished piece, not a per-gram rate.
One unit Americans will meet in the jewellery trade is the pennyweight, abbreviated dwt: one pennyweight is 1.55517384 grams, and 20 pennyweights make one troy ounce. Jewellers, pawnbrokers and scrap buyers in the US still weigh gold in pennyweights, so a quote of “per dwt” is common when selling old jewellery or scrap. Use the Gold Price per Gram, Tola and Ounce Converter to put a per-dwt, per-gram or per-troy-ounce quote on the same unit before comparing. The tola (11.6638 grams) is not used by American shops — it is common in South Asia and the Gulf.
Karats in USA: 14K for everyday jewellery, 18K for fine pieces
In the United States, 14K gold is the dominant jewellery grade: 14K means 58.33% pure gold — 14 parts gold out of 24 — and it accounts for roughly 90% of engagement and wedding rings sold in America. It is hard enough for everyday wear, holds up well to scratches, and costs less than higher karats.
For fine jewellery, the grade is different: 18K gold — 75% pure — is the standard for high-end rings, necklaces and designer pieces, with a richer yellow colour. 10K gold — 41.67% pure — is the legal minimum karat that can be sold as gold in the United States, used for budget and mass-market pieces.
For investment, the grades are higher still: 24K gold — 99.9% pure — is the usual choice for bars and coins, bought for the metal, not for wear. The two best-known American gold coins show the split: the American Gold Eagle, minted since 1986, is 22K gold and holds one troy ounce of pure gold in a harder alloy; the American Gold Buffalo, minted since 2006, is 24K gold and holds one troy ounce of pure gold. The Eagle is harder and more durable; the Buffalo is pure. Both track the same spot price, and dealers sell both at the spot price plus a premium — the premium is the dealer’s margin, usually smaller on the 1 oz size than on fractional sizes.
Use the Gold Weight and Purity Calculator to check how much pure gold is in a piece: enter the weight and karat and it gives the pure-gold weight — a 10-gram piece of 14K gold holds 5.833 grams of pure gold, and a 10-gram piece of 18K holds 7.5 grams. Jewellers and scrap buyers work on the pure-gold content.
Where to buy gold in USA
The United States has two famous gold districts — one on each coast — plus two giant online bullion dealers that ship nationwide. Because the price is national, the choice of place is about the shops and the making charges, not the rate.
47th Street Diamond District, New York — the main gold district
West 47th Street between Fifth and Sixth Avenues in Midtown Manhattan is the heart of New York’s Diamond District — the largest concentration of jewellery businesses in the United States, with hundreds of dealers, wholesalers and retailers packed into a single block. Gold buyers, coin dealers and jewellers sit side by side, so comparing two or three shops takes minutes.
Named dealers on the street include AGR Gold (American Gold Refinery) at 31 West 47th Street, Suite 504, and Gold and Silver Buyers at 55 West 47th Street, Suite 203 — both buying and selling gold, silver and coins, typically open about 10:00 AM to 5:00 or 6:00 PM, Monday to Friday. View the 47th Street Diamond District on Google Maps.
Los Angeles Jewelry District — the largest in the country
The Los Angeles Jewelry District, in Downtown Los Angeles along Hill Street between 5th and 8th Streets (90014), is the largest jewellery district in the United States, with around 5,000 wholesale and retail jewellery businesses in a six-block area, mostly on Hill Street, Olive Street and Broadway. It is reached by Metro Red or Purple Line to Pershing Square station.
The best-known building is the International Jewelry Center at 550 South Hill Street, with over 400 retail and wholesale jewellery businesses under one roof, and the St Vincent Jewelry Center at 640 South Hill Street is another landmark. Competition between so many shops side by side is the best way to get a fair making charge — but check the hallmark and karat carefully, and get a written receipt. View the Los Angeles Jewelry District on Google Maps.
Online bullion dealers: APMEX and JM Bullion
For coins and bars, most American buyers start online. APMEX (American Precious Metals Exchange), one of the largest online precious metals dealers in the United States, is headquartered at 226 Dean A. McGee Avenue, Oklahoma City, OK 73102, in the historic former Federal Reserve Bank building. JM Bullion, founded in 2011, is headquartered at 11700 Preston Road, Suite 660153, Dallas, TX 75230. Both publish live prices, sell American Gold Eagles and Buffaloes alongside bars from major mints, and ship nationwide — comparing their premiums takes minutes. Both are primarily online dealers: check whether a given location offers walk-in service before travelling to it.
Local independent jewellers are worth a visit too, especially for custom work, repairs and engagement rings — and for selling back old gold, where a buyer who tests the piece in front of you is often the most transparent option.
What you will actually pay in an American shop
The price on the Gold Price in USA page is the raw spot rate. The price you pay in a shop is usually higher — shops add making charges, their margin, and sales tax where it applies. Making charges are the part you can actually negotiate: the spot price is the same for everyone, but making charges vary from shop to shop — and on 47th Street and in the Los Angeles Jewelry District they vary a lot.
So compare the total price of the same piece in two or three shops, not just the per-gram rate. Work out the metal value first with the Gold Value Calculator — enter the weight and karat and it gives the metal value at the live spot price, before dealer charges. The difference is what you are paying for craftsmanship, brand and the shop itself. Price 14K jewellery against the live 24K rate using the karat fraction (14/24), and 18K using 18/24.
Tax on gold in USA: no federal VAT, state rules vary
There is no federal VAT or federal sales tax in the United States. Sales tax is set state by state, and the rules differ — so the same purchase can cost different amounts in different states. Many states exempt investment-grade bullion and coins from sales tax, while jewellery is usually taxed where sales tax applies.
Before you buy, check your own state’s rules — and ask for the bill split into metal value, making charge and sales tax, each on its own line.
Buying tips for USA
- Check the live price on the day you buy, and value the piece first with the Gold Value Calculator.
- Compare making charges across two or three shops — on 47th Street and in the Los Angeles Jewelry District the shops are side by side.
- Check the hallmark and karat — 14K is usually stamped 14K or 585, 18K is stamped 18K or 750. If a piece is unmarked, have it tested first.
- Check the pure-gold content with the Gold Weight and Purity Calculator — stones, clasps and springs add weight without adding gold.
- Match the karat to the purpose: 14K for everyday jewellery, 18K for fine jewellery, 24K for bars and coins.
- Compare dealer premiums on coins and bars — the premium over spot is the dealer’s margin, and it varies by dealer and by coin size. American Gold Eagles and Buffaloes are the easiest coins to sell back, because every dealer recognises them.
- Check your state’s sales tax rules before you buy — many states exempt investment bullion and coins, while jewellery is usually taxed.
- Keep the receipt and certificate for resale.
