Buy underpriced jewelry at estate sales and thrift stores and resell for melt value or to collectors — testing purity is the entire skill.
Why that grade Figures reflect general precious-metal-picking market patterns; no independently audited sample found. Course-seller index 3/10.
Figures are researched estimates, not guarantees. Check local rules before you trade.
Estate sale and thrift store jewelry is frequently sold well below true melt value by sellers who haven't checked its precious-metal content.
A $5-20 thrift 'costume jewelry' find that's genuinely solid gold can be worth $50-300+ in scrap value alone; reliable testers report 50-150%+ margins.
Someone with the patience to develop real testing skill and check every promising piece rather than guess.
Anyone unwilling to buy proper testing equipment and skip the guessing game — hallmarks alone are not reliable proof of purity.
Misidentifying gold-plated or gold-filled items as solid gold is the single most common costly mistake — always test, never assume from hallmarks alone, since hallmarks can be faked or belong to a plated item.
6 steps to your first paying customer
Buying in is not one of these steps — the Startup cost above is what you need in hand; this is what the steps cost on top of it.
Hallmarks and weight/feel give a starting signal, but never a final answer.
Done when You can correctly identify at least 3 common hallmark stamps and explain why a stamp alone isn't proof of purity.
Watch out: A convincing-looking hallmark can belong to a plated item — this is not proof of purity on its own.
Verify purity before buying — this is the single most important step in the entire business.
Done when You've tested at least one piece with an acid kit or electronic tester and confirmed karat/purity before paying for it.
Watch out: Skipping testing to save time is how flippers overpay for plated items.
The rest of the playbook: what to charge, what you need in place before you take money, where the first customers come from, and what each step costs.

Scale into a small secondhand jewelry/scrap buying operation with a storefront, or specialise into antique jewelry resale for higher margins.
Same idea, different rules. One playbook, with the facts that actually differ overlaid per market.
Gold has deep cultural significance and an established resale market, though dealing at volume requires proper registration under Indian jewelry trade regulations.
Gold trading is significant in the UAE culturally, but dealing in precious metals as a business typically requires proper trade licensing.
Secondhand dealer licensing (via local council) is commonly required for regular jewelry/scrap buying.
Many states require secondhand dealer licensing for regular jewelry/scrap buying, often with ID-recording requirements.
Sell handmade goods at local markets — the stall fee is a sunk cost the moment you pay it, rain or shine.
Clean and tune underpriced used bikes for resale — low capital per unit, and tune-up skill is a real barrier that limits casual competition.
Sell homemade baked goods and preserves under your local 'cottage food' exemption — most laws explicitly ban shipping, even though that seems like the obvious growth channel.
