Large Hand-Cut Crystal? Martini or Champagne Vessel: Is It MIKAS?

~10 ounce capacity; 6 5/8” high, ~4 3/4” rim diameter, ~1 3/4” foot diameter, ~3 5/8” stem length. Weight, empty is ~9 3/4 oz. I'm not able to differentiate glass from crystal; it is not UV reactive. When the rim is plucked with a fingernail, its ring is very high, crisp an’ clean. All the wheel work is hand-held; lots of evidence of irregularity, everywhere.
Does this simple cone-shaped vessel have a specific name?

Its mark is quite clear: MIKAS, with an R inna circle. I have not yet found that maker, but expose it to this forum, where I hope success may occur. All search results insist on showing MIKASA; Drat!
Thank you all for your patient help...an' for lookin!

 

You can do a photo search at Replacements, this is what I got:

Excellent, Marie...Thank you!
I was eventually gonna try the Replacements site, but still cannot square MIKASA with the mark on mine. Also, China, blown glass, dimensions an' capacity are good, an' the general shape is ok...but the angle of the cone is too acute to match mine. More to be learned, seems to me.

 

The mark does look like the MIKASA mark... minus the A, of course.
Perhaps a knock-off?

 

Huh...I hadn't considered that. You may be right!
