Gold Value Guide
How Gold Value Is Calculated Before You Sell
A clear walk-through of the main factors that affect a gold offer so you know what to expect before you visit TWG Cash for Gold in Ewing, NJ.
Section 1
What affects a gold offer.
Four main factors shape what a buyer can offer for your gold. None of them is a secret — and a good in-person valuation explains how each one applies to your item.
Weight
Gold is priced by weight, typically in grams or pennyweights. Heavier items contain more gold and can carry more value.
Purity (Karat)
Karat shows how much gold is in the alloy. 24K is pure gold; 14K and 10K contain less gold mixed with other metals.
Market Factors
Gold prices move with the global market. Live spot price is one input the store considers when pricing items.
Item Type & Condition
Jewelry, coins, and scrap can be evaluated differently. Damage, missing parts, or stones can affect the offer.
Section 2
Why karat purity matters.
Karat tells you how much actual gold is in an item. Higher karat means more gold per gram, which generally means a higher per-gram offer.
About 41.7% gold. Common in everyday jewelry. Pays less per gram than higher karats.
About 58.3% gold. The most common karat for U.S. jewelry.
About 75% gold. Popular for fine jewelry and higher-end pieces.
About 91.7% gold. Often seen in bullion-style jewelry and imported pieces.
Pure gold. Soft and used mainly in bullion bars and coins, not everyday jewelry.
Section 3
Why online calculators are only estimates.
Online "cash for gold" calculators can give you a rough idea of what a piece might be worth based on weight and purity. They are useful for ballpark numbers — not final offers.
What calculators usually do not include:
- Item condition, missing pieces, or damage
- Hands-on testing to confirm purity
- Refining, handling, and other operating considerations
- Local market context and item-specific details
Treat any calculator number as a starting point, then bring the item in for an in-person review you can ask questions about.

FAQ
Common gold value questions.
There is no single number. Offers depend on weight, karat purity, item type, condition, and current market factors. The best way to know is an in-person review.
No. Online calculators give estimates. They may not account for testing, item condition, or local evaluation details. Use them as a rough reference, not a final price.
Yes. 14K contains less pure gold than 24K, so per-gram value is lower. Weight still matters, so a heavier 14K piece can carry meaningful value.
Yes. Broken chains, single earrings, and damaged pieces are still evaluated by weight and purity.
No. You can hear the offer, ask questions, and decide whether to sell. There is no pressure either way.
