First off here is a probably identical ring for a table serviette with a much clearer and apparently identical trademark: SL under what appears to be a crown followed by the word Denmark and the number 951.

This owner thinks it is Sterling silver which would be identified as .925 silver under Danish rules if it was identified at all.
Now you don’t have to sell sterling silver in Denmark or anywhere else with an identify to it, but remarkably few people selling actual sterling or better silver think marking it Sterling or .925 is detrimental on what is otherwise white metal
In Denmark hallmarks are voluntary so it’s the silversmiths themselves who makes up the rules for their own self-protection.
When you see “Denmark” and “951” on a napkin ring, it could be taken to refer to a design or model number paired with the item’s country of ostensible origin mark, rather than a silver purity hallmark.
The number “951” is a most charitably described as a pattern/design number used by the silversmith to identify the specific style of the napkin ring during production.
In silver manufacturing, standard sterling silver is marked as .925\ (92.5% purity). If the ring is made of real silver, it will almost always have a separate .925 mark stamped on it. If you do not see a 925 or 830, another common Danish silver standard stamp, the item is likely silver-plated or made of base metal.
One final hint. The Danes spell their country with an “a” following the D not an “e” and while the French prefer a minerva standard of .950 silver — mostly to be different to and slightly better than the English, nobody had assayed and commercially advertised a .951 standard silver.
Conclusion: Take it to you local friendly silversmith and have him test what is otherwise a delightful rose-patterned napkin ring, apparently one quite frequently sold by its incidence online.
My guess would be nickel silver, but who knows from photos.

Sterling silver has a specific gravity of roughly 10.36 while German silver is lighter at about 8.5.
We know the advertised ring was 29.8 grams and yours is probably the same.
If the advertised ring is nickel silver and had it been sterling it would be 10.36/8.5 X 29.8 grams. or 36.32 grams.
Of course the obverse is also true, if it is sterling and still only 29.8 grams then had it been nickel silver it would be 8.5/10.36 X 29.8 grams or a mere 24.45 grams.
To determine which is what exactly you need a beaker of water with a measure on it and something that is exactly 29.8 grams of sterling silver.
Or a naked Greek philosopher called Archimedes taking a bath and shouting “eureka!” when he figured out the theory of water displacement, or his wife left the hot tap running too long.

And another one:
Eisenberg-Lozano.
Eisenberg-Lozano Inc. is an American silver and metal importer based in New York City. Founded in 1953 by Arthur Eisenberg and Neal Lozano, the brand is widely associated with Denmark, where it outsourced its production of high-quality tableware and cutlery.
Origin and Production: Eisenberg-Lozano did not have its own factories in Denmark. The company commissioned designs from Danish craftsmen and steel mills and then imported them to the American market. Materials and Style: These products typically represent a mid-20th century (Mid-Century Modern) style. They included silver-plated vessels, enamel-coated bowls, stainless steel, and teak. Markings: The base of the items often bears the distinctive “E-L” mark or the full name “EISENBERG-LOZANO” with the addition “DENMARK.” From 1964 to 1970, the company also used a crown logo. Today: In 1970, the company was acquired by Kirk International. As a result, original “Eisenberg-Lozano Denmark” products are now prized and sought-after vintage collector’s items.

Wow-I am much smarter/informed now and I really appreciate the information. Thanks for your smarts and brainpower. Will take them (there are four) and get them checked for silver content. I paid 95 cents for all four and they shine up pretty so no losses. Thanks again-di
As for the other comment-I hope the water was hot because all that is above my pay grade though much appreciated…lol- di
Thank you! I have spent hours looking and that’s it! To your ‘welcome Mam’-thank you sir!
Very happy…di
Thank the Guildhall for the explanation. I’m playing the village idiot here.
