Hello
You are welcome.
In almost „normal“ Guides for Silver ware seldom you would find marks of makers for overlay technique of silver on Glass.
This technique was very popular especially in the so called »Art Nouveau« period around 1900.
Maker of your vase in overlay technique was
Matthews Co., from Newark, NJ. They were active from about 1907 until about 1936. They were followed up by Hickok — Matthews Co.
They were makers of hollowware in silver, and made also items like yours.
Please look here for their mark:

The overlay technique is made by electro plating processing, also called galvanic plate. Many makers haven’t had an own glass ware factory — they’ve buy it from glass ware factory. High end quality glass ware factories haven’t exist only in Bohemia, but also in America; e.g. with »Steuben Glass«.
To make this overlay would be used pure silver of »
999-1,000« fineness — hence the mark on your item.
First mark, on the left, is maker’s mark. Then following numerical are an indication for model number and pattern of overlay.
Please look here; there is some more information on glass overlay with silver:
