Questions, answered

21K gold price — FAQs

How much is 21K gold worth per gram today?

The current estimated 21K melt value is $122.33 per gram. This applies an 87.5 percent purity factor to the approved live gold-price source. A purchase offer can differ after testing, non-gold weight, transaction costs and complete-item demand are considered.

What does an 875 stamp mean on gold jewelry?

An 875 mark generally indicates 875 parts gold per thousand, which is equivalent to 21K or 87.5 percent purity. Check the inside of a ring, the clasp area of a chain or bracelet, the back of an earring, or the bail of a pendant. Have the item tested because markings can be worn, missing or inaccurate.

Is 21K gold real gold?

Yes. Solid 21K gold is a high-purity alloy containing 87.5 percent gold and 12.5 percent other metals. The alloying metals affect color, strength and wear, but do not make properly tested 21K gold less genuine.

What is the difference between 21K and 22K gold?

21K gold is 87.5 percent pure, while 22K gold is approximately 91.7 percent pure. At the same net weight and live gold price, 22K has a higher melt value. The better selling outcome can still depend on stones, maker, condition and demand for the complete piece.

How should I value 21K jewelry bought outside the United States?

Start with the mark, net weight and professional purity test rather than assuming the item follows US marking conventions. Photograph any script, maker signatures, assay marks or receipts. These details can help identify the piece and may matter if it has value beyond its gold content.

Do gemstones add value to a 21K ring or necklace?

They can, but the answer depends on the type, quality, condition and saleability of the stones. A melt-only quote may subtract their weight without valuing them. Request an itemized assessment before allowing a stone-set piece to be dismantled.

Do gemstones affect the value of 22K jewelry?

Gemstones and other non-gold components may be included in the item’s total scale weight but excluded from its net gold weight. Some stones may have separate value, so assess the complete item before removing them or treating the jewelry as scrap.

Can damaged 21K jewelry still be sold?

Yes. Broken chains, bent rings and single earrings can retain gold value when the purity and net gold weight are verified. A signed, antique or well-made piece may also deserve an intact-item review before it is treated as scrap.
