P4 is a mix of metals(gold,silver,platinum & palladium)that has the look of white gold, but is much more affordable. It can be rhodium plated(what they do with white gold to keep it lustrous),but it holds it's tone better than silver does.
The SR on the ring is probably the vendor's stamp. One that I know of that does P4 items uses the stamp SRI. It is sold through many finer jewelry store chains.
Hope this helps you.
I have a ring that has a stamp on the inside of P4SR and would like to know what it may mean. I was told that the ring was 10kwg but I think it maybe silver.
P4SR typically stands for "Platinum 4 Stone Ring," indicating that the ring is made of platinum and features four stones set on it.
"P4SR" marked on a ring could indicate that the ring is made of platinum (P), with a purity level of 950 parts per thousand (4/5). The "SR" could be a maker's mark or hallmark indicating the manufacturer or designer of the ring.
Honey, a stamp on a ring doesn't mean squat when it comes to its value. Gold is gold, whether it's stamped with a fancy code or not. Take that ring to a jeweler and get it appraised properly if you want to know its worth.
One can find a ring sizing chart at many jewelry stores. Each store will have a poster of what each ring size means and how big each ring size actually is.
When sizing tungsten rings, it is important to consider factors such as the width of the ring, the comfort fit design, and the shape of the wearer's finger. The width of the ring can affect how it fits on the finger, while a comfort fit design can make the ring more comfortable to wear. Additionally, the shape of the wearer's finger, such as if it is wider or narrower, can also impact the sizing of the tungsten ring.
Sizing sterling silver jewelry is done differently than sizing gold jewelry. Jewelers located in several different places like Jared's Galleria of Jewelry are knowledgeable in how to size all types of jewelry. Sizing is typically done by taking the ring and cutting a portion of the band, and then soldering the gap in order to downsize the ring.

The number 58 on a ring typically indicates the ring's size. In this case, it often corresponds to a specific measurement in millimeters of the inner circumference or diameter. Different sizing systems exist worldwide, so it's important to check the context or sizing chart to understand its exact significance.
You can use a set of ring sizers, a graduated ring stick, or even a round object like a marker or dowel to shape and size rings instead of a ring mandrel.
A ring with a diameter of 2.5 cm corresponds to a US ring size of approximately 10. This measurement translates to about a circumference of 7.85 cm. In other sizing systems, it may vary slightly, but it generally stays within the same size range. Always check with a specific sizing chart for the most accurate fit.
