WHAT IS CUTTLEFISH BONE CASTING?

Cuttlefish bone casting is one of the oldest forms of casting for jewelry-making creativity.

Cuttlefish bone is the center bone of a squid-like mollusk, one of the earliest known casting processes. In direct casting, molten metal directly fills a design carved into a mold surface, producing a mirror image of the design in the finished cast object.  Also, due to its organic origin, cuttlebone has growth rings, like beautiful wood grain or wave texture, it make every piece of beautiful uniqueness as no two items look exactly the same.

If you see the number 925 stamped on gold jewelry, chances are that the mark does not refer to the gold content of the piece.

These rings have “925” stamped on them, meaning that they are not made of solid gold.

925 is a standard sign used to mark sterling silver, and the meaning of the stamp is that the silver content in the piece is 92.5% (i.e., the remaining 7.5% is comprised of other elements).

Why Stamp Gold Jewelry with a Silver Mark?

Perhaps because the “gold” jewelry you are looking at is not actually made of gold.

It seems puzzling why a gold piece would be marked with a stamp commonly used for silver.

This is not so surprising, however, and most likely means that the jewelry is not made of solid gold but is actually a silver piece that has been gold plated. You can see gold-plated jewelry here.

In this case, the 925 number makes sense, as it denotes the purity of the underlying silver core, not that of the gold plating.

A “925” Mark Is Usually Stamped on Gold Vermeil

So, if your gold piece is marked with a “925” stamp, what you have is likely gold vermeil (pronounced ver-may). This is the name used to denote silver jewelry covered with a thin layer of gold. Click here to browse gold vermeil items.

This ring made with gold vermeil.

For a piece of jewelry to be sold as gold vermeil in the U.S., its gold plating needs to be at least 10 karats, or contain about 42% gold, and its thickness should be at least 2.5 microns.

How to Tell If Your Jewelry Is Really Just Gold Plated

If you want to make sure that the “925” mark on your jewelry means that it is gold plated instead of solid gold, the first thing to do is check for other stamps.

Signs commonly stamped on gold-plated jewelry are GP, GEP, RGP, HGE, and HGP.

If there are no stamps indicating that the jewelry might be plated, then you can have the piece tested. Jewelers do such tests by applying acid to a very small piece of material taken from the jewelry.

Acid tests are usually meant to establish the karat of a gold alloy, but they can also help find out if a piece is gold plated.

Determining the Purity of Gold Plating

Acid testing can reveal the gold content of the plating.

Very often, gold-plated pieces are covered with 22-karat or 24-karat gold, which is rarely used to make solid-gold jewelry, as high-purity gold is too soft.

If there are any karat markings on the piece, they can also indicate the karat of the plating.

For example, a mark that reads “22K” likely means that the top layer of the jewelry is 22-karat gold.

This gold bracelet is actually plated with 18K gold.

Gold karats are often expressed as parts per thousand in the form of three-digit numbers stamped on the jewelry.

Here are the most common karat markings (on the left) and their equivalents in parts per thousand (on the right):

• 24K – 999
• 22K – 917
• 20K – 833
• 18K – 750
• 14K – 583
• 10K – 417

(To convert purity numbers from parts per thousand to a percentage, simply divide by 10.)
