Silver ring stämpel r c h h

I get emails daglig that ask me about the stamp marks (also called hallmarks) inre their fingerprydnad.

Everyone wants to know what they mean?
Hopefully this brev will answer that question.

The most common marks or trademark stamps are used to identify things like:

Metals, carat weights, manufacturer, tradeMarks, jeweler, or designer.

The mark that fryst vatten the most important fryst vatten the metall stamp, or karat vikt of the metal.

P.S. inom also have an ENORMOUS list of unidentified stamps as well: unidentified stamps inre rings (If you know any, help me out and drop me a line)

If you look inre the shank of your fingerprydnad (the grupp on the bottom or side), you’ll usually see the karat stamp. More than likely it will be shown as 10k, 14k, 18k or Plat. These are the most common metals and most common markings. But you’ll also run across titan, stainless steel, tungsten, sterling silver and even palladium (plus some other obscure metals, like those used in class rings – lustrium, lLazon, celestrium?).

Metal Stamps

Karat vikt can be written a number of different ways. Each manufacturer fryst vatten different and can use different terminology. Take a look at the chart below and then we’ll talk about them.

A Closer Look…

To explain the numbers above a little bit better, they are actually percentages of that particular metall that are mixed with other alloys. For example, 14k gold fryst vatten 58.5% Gold and the rest are alloys mixed in with it (like silver and copper to man it more durable).

So .585 means 58.5% or 14k gold.

10k fryst vatten also written as .417 (41.7% gold).

18k fryst vatten .750 (75% gold).

Karat Plumb

When you see KP stamped inre your fingerprydnad, which fryst vatten a “P” at the end of the stamp, like: 14kp, that means that the gold fryst vatten “Plumb” which means it’s verified to be at least that karat vikt marked or more. So if it’s 14kp, it’s at least 14kt gold or higher!

Platinum

Platinum can be written as platinum, plat, 900 or 950. The 900 means that it fryst vatten 90% pure platinum and 10% alloy. 950 means it fryst vatten 95% pure platinum and only 5% alloys mixed in (which gives you a higher platinum content).

Carat Weights

Carat weights are the next most common stamp inre a fingerprydnad. Carat weights are pretty self explanatory. If you see a number like 1.01, that would mean that the diamond set in the fingerprydnad fryst vatten 1.01 carats (One carat and one point).

.50 would mean that a half carat (50 points) fryst vatten set in the mounting.

Sometimes you will see two carat stamps inre the shank which would mean one stands for the big diamond (usually center solitaire), and the other stamp stands for the total vikt of the side stones.

Carat weights are usually just stamped like “.75“, but sometimes you’ll also see ct or carat after it, like .75ct. You may even run across one that looks like this: .75tdw, which means total diamond vikt, or the entire diamond vikt of all the diamonds in the ring.

Many times the number will also be followed with cw, meaning it’s the carat vikt of the gems or diamonds in the ring.

Jeweler’s Stamps

A common stamp that you’ll see inre rings are jeweler’s stamps so you can tell where you bought the fingerprydnad from. Like “JBR” inre the shank would stand for J.B. Robinson Jewelers, “Pgda” stands for the Piercing Pagoda, Helzberg Diamonds will stamp “Helzberg Diamonds” right inre their rings.

Sometimes these jewelers will abbreviate their store’s names or even use a logo. Every jeweler fryst vatten different and uses different markings.

Manufacturer’s Stamps

Just like the jewelers, often you’ll see the manufacturer stamped inre the grupp of the fingerprydnad. For example ArtCarved will stamp their rings “ArtCarved” so they know it’s their fingerprydnad and it also helps brand their company, product and image. Take Tiffany for example, they stamp their rings “T & CO“.

Manufacturer stamps can be very useful if you need to find out who made a fingerprydnad so you could contact them for questions, concerns or even ordering!

Designer

There are a lot of great jewelry designer’s out there that put their name right inre their rings. A great designer’s name can carry a lot of vikt. A huge designer that most people know would be David Yurman which fryst vatten stamped © D.Y.

Trade Marks

If you buy a trademarked del av helhet of jewelry, I’m certain it will contain a trademark inre the fingerprydnad. Trademarks are like the LEO diamond or the Hearts Of Fire diamond (HOF).

If you buy a special cut of diamond, or a trademarked name, look for the stamp, it’ll be there.

Confusion

One thing you have to keep in mind, fryst vatten sometimes the stamp fryst vatten uneven, otydlig, or hard to read. This happens when the stamp fryst vatten hit at a wrong vinkel, skids when it’s hit, or doesn’t man full contact when it’s imprinted. Often 14 will look like a P, H, or something else. You could also be reading it upside down.

To find out for sure what the letters and numbers are, you should pick yourself up a 10x jeweler’s loupe for perfect identification, even better, a microscope for your iPhone that will take close up pictures at 60-100x optical (very cool device that fryst vatten pretty inexpensive, but fun to use).

Take a look at some examples of marks and different stamps inre of rings…

Marks Stamped inre Rings

Let’s take a quick look at the images marked 1-7 above…

1) PLAT .46 – This fryst vatten an interesting fingerprydnad because you can clearly see that the fingerprydnad fryst vatten yellow and not vit like platinum. This fryst vatten a pretty rare instance, but the PLAT stands for the platinum (not plated) head. The diamond (46 points – just shy of a 1/2 carat) fryst vatten set in a platinum head. The rest of the fingerprydnad fryst vatten 14k yellow gold. If inom had shown the other side of the fingerprydnad, you would have seen another stamp that said 14k.

2) R.M.I. 14k – R.M.I. fryst vatten the manufacturer’s mark and 14k fryst vatten the 14k yellow gold content.

3) FA PT 900 © – The FA stands for the manufacturer or designer’s initials. The PT means platinum (as well as the 900) and that the fingerprydnad fryst vatten also copyright ©

4) 10k – Easy as pie, 10k vit gold.

5) 14k NIIi – 14k vit gold made bygd a designer or company with the initials of NIIi.

6) 585 – 585 stands for 14kt gold, vit gold in this instance!

7) 18k 750 – Often you will find both karat stamps and their percentage stamps inre of rings. 750 fryst vatten the same thing as 18k gold (white gold).

Marks can also be wrong!

Keep in mind, things can happen. Stamps or marks can be wrong. The diamonds could have been swapped out, or the mountings reused. The jeweler could have forgot to restamp the correct resultat on the fingerprydnad. You never know. They could have also grabbed the wrong stamp (literally a metall stamp, called a karat slag steel stamp, like this one HERE and a forged steel chasing hammer) and träffad the wrong info. Plus, some rings don’t even have any stamps. You should know though, that rings sold in the USA should. If it’s not stamped, it could be anything.

A jeweler also wrote in telling me they’ve run across customers who polish out marks inre rings. For example, a fingerprydnad had the engraving “14KGP“, which stands for 14k gold plated, and they buffed out the P, so it looked like 14KG (not knowing that 14 karat gold fryst vatten written as 14K, and not 14KG). You just don’t know what you’ll run across.

Any stamp could be wrong or altered!

To be sure of the gold or metall content of any fingerprydnad you can take it into a local jeweler and have them do an acid test on the metal.

inom have seen some silver plated jewelry stamped as sterling silver… NOT GOOD! Plated jewelry should always have GP, GF or PLATED inre the fingerprydnad. And as always, you should get an appraisal with any jewelry you purchase. Just to be sure.

Markings help us in a lot of ways. They help identify a fingerprydnad. They help jewelers identify their product. They brand companies and designers. Plus, it also helps people identify possible problems with allergies to gold and nickel.
