Dark blue, believe carnival glass, diamond cut on top, etc. creamer & sugar bowl. Can't find name to save my life. Someone HELP

I purchased this set of dark blue, believed to be carnival glass, creamer and double handle sugar bowl at an antique auction several years ago. They are heavy, thick, from top to bottom 1 3/4", opening 3 3/4", bottom is 1 5/8", and creamer is 6" from handle to handle. At the opening of each, looks like diamond cuts and grooves (not sure what to say about that), on the handles diamond looking cuts, beautiful cut into glass designs which I can't figure out what they look like and is all around sides if you can tell by pictures. The bottom of each has 8 cut in designs with 3 cut in grooves in each design, and oh my gosh, I can't tell you just how beautiful they are. It kinda looks like on the inside of each, at the bottom, the glass is sorta pressed together. I have actually recently took them out to do a little, I thought, research to find out the maker, design name, and anything else I could find out, and stayed up several nights until 4AM to 5AM like a nut on this computer and it cant help me. (Sure wish I knew what it's worth too.) I'll tell you this. I have learned so much more about glassware than I knew. I have a lot of collectible Vintage and Antique glassware and I am shocked. I am so glad I have an alarm system especially now. I would shout loud enough, I hope, so they could hear me, if someone can help me. Actually it's 1:06 AM now, yesterday I stayed on this dang computer till 5:30 AM this morning. I'm ready to give up, ready for some sleep, and THANKS IN ADVANCE to some good sameritan out there somewhere that sees this and knows something about it. (My name is Gerry.)
