RST on a ring likely stands for the initials of the metals used in the ring, which could be rose gold, sterling silver, and titanium. It is common for jewelry makers to mark their pieces with these initials to denote the materials used in the piece.
"SR" inside a ring likely stands for "Sterling Silver." This indicates that the ring is made of sterling silver, which is a high-quality, durable metal commonly used in jewelry making.
GSV typically stands for Gold Steel Vanadium, indicating the metal composition of the ring. It means that the ring is made of a combination of gold, steel, and vanadium, giving it strength and durability.
The marking "R STER" on the inside of a ring typically indicates that the ring is made of sterling silver. "R" stands for "sterling" and confirms that the metal content is at least 92.5% pure silver.
SR on a ring likely stands for "Sterling Silver," indicating that the ring is made from sterling silver. Sterling silver is a popular metal alloy consisting of 92.5% silver and 7.5% other metals, typically copper.
SRB 1 stamped on a ring likely indicates that the ring is made of sterling silver. The term "SRB" might also refer to the manufacturer or designer of the ring. It's a common practice for jewelry makers to stamp their pieces with such markings for authenticity and identification purposes.
The 5.5 in RST 5.5 means that the interrupt vector is located between RST 5 and RST 6.

It means 14K PBD Peter Brams designs
If it is a vintage ring, it may be from the Traub company that made engagements rings circa 1925 and marked their rings with a TT.
SECO was the trademark of Stein and Ellbogen, a jewelry wholesaler.
i have the same 18 marked 750 gold ring
What does a ring that has the markings in this order 925 fd and then CM on the opposite side!
Because that's how Intel designed the 8085. In addition to the 8080 type interrupt on the INTR pin, Intel chose, for the 8085, to implement four new interrupts, RST 5.5, RST 6.5, RST 7.5, and TRAP, each of which would not require the interrupting device to provide a vector. The naming convention of x.5 was simply in recognition that Intel placed the implicit vector halfway between two other RST vectors. As an example, RST 6.5 is halfway between RST 6 and RST 7. Since RST 6 and RST 5 are eight bytes away from each other, placing RST 6.5 in between would place a limit of four bytes, and four bytes is enough to place a three byte JMP instruction. The decimal and hex addresses of all of the vectors are... RST 0 - 0 - 00H RST 1 - 8 - 08H RST 2 - 16 - 10H RST 3 - 24 - 18H RST 4 - 32 - 20H TRAP - 36 - 24H RST 5 - 40 - 28H RST 5.5 - 44 - 2CH RST 6 - 48 - 30H RST 6.5 - 52 - 34H RST 7 - 56 - 38H RST 7.5 - 60 - 3CH
i have i ring with two different colours gold on it but it just marked mb is it gold
