Organizing precious metals starting with “Is this really gold?”
When organizing your home, you may come across accessories of unknown material.
“It says K18, but what does that mean?”
“It’s a gold-colored necklace, but is it really gold?”
“Does a platinum ring I bought a long time ago still have value?”
These are common initial concerns for those considering selling gold or precious metals.
Since it is difficult to judge gold and platinum by appearance alone, it is important not to dispose of items of unknown value based on your own judgment.

What are the differences between K18, K24, etc.?
When looking at gold products, you may find hallmarks such as “K18” or “K24”.
These are notations used to indicate the purity of the gold.
Generally, K24 is close to pure gold, while K18 is gold mixed with other metals.
In jewelry, K18 is often used for its strength and ease of processing.
However, the appraisal value is not determined solely by the hallmark.
Weight, purity, and the market price at that time are also factors.
Checking platinum in the same way as gold
When organizing jewelry, you may find platinum products as well as gold ones.
They are often used in wedding rings and necklaces, and you may have seen hallmarks like “Pt900” or “Pt850”.
It is not uncommon to not remember the purchase price of rings or necklaces bought a long time ago.
When considering selling platinum, it is easier to organize if you start by checking the material and its current valuation.
How are ingots appraised?
You may be searching for ingot purchasing services in Okazaki.
For ingots, checking weight and purity is important.
Also, since different dealers accept different types of ingots, the brand is another important factor.
Because gold market prices may differ between the time of purchase and the time of sale, you cannot determine the current value based solely on ‘how much you bought it for in the past’.
Gold market prices fluctuate.
If you are considering selling, one way to decide is to check the appraisal value at that time.
What about broken necklaces or single earrings?
For gold and platinum products, even if they cannot be used as jewelry, they can sometimes be verified as raw materials.
For example,
・Broken necklaces
・Deformed rings
・Single earrings
・Old-fashioned jewelry
and so on.
Instead of ‘throwing it away because it’s unusable,’ try checking if there is still value in the material.
