Help with crystal pattern and maker

I got 6 of these in an old box. They have a gold foil stamp for the 24% lead crystal. The top is unusual, it’s like a magnifying glass at the rounded part of the bottom. Hand blown I think. Any ideas of what the pattern may be so I can get a search going for a maker? Their really unusual

 

Have you tried the photo search option on https://www.replacements.com/ ?
A good photo against a plain background, shot straight from the side, will be most useful.

 

Please post a good quality close-up photograph of the sticker.

And just to reiterate, photographs of an item shot from straight on and in the correct orientation against a plain background will help us help you.

Unknown Manufacturer, UNK15983 | Replacements, Ltd.

 

That's where the sticker might help; it appears to have a company logo.

that's the pic we were looking for..

 

Looks like a company logo. All the results on Google Lens are coming out of Russia.

I found a Bulgarian website where someone was selling what they described as “old Bulgarian hand-engraved crystal” with the same sticker.

 

Glasses were boxed. Here are the images for listing #25647954. Google Translate identifies the language as Bulgarian.

Thank you

 

So we're not yet able to identify the maker, but because of the sticker, we know the maker is most likely Bulgarian.

The maker is indeed Bulgarian, Кварц Kvartz (Quartz) JSC, from Sliven, they got bunkrupt in 1997 but maybe some of the facilities are still operational as they have an online shop and also a small physical shop in Sofia. Here is the link in Bulgarian:

In addition - we have or more precisely had good quality of crystal production although not well known beyond our borders, not like Bohemia for instance. I myself have a set of cognac cups (small ones) just of the same pattern as shown here. I like them very much and don't use, keep them safely stored. Stupid, I know, but...
