Hi and welcome,
Wayne is quite correst of course!
GMB members do not tend to value items specifically. As these are recognisable, you will be able to go to ebay etc.. and have a look what prices they fetch. Your relative had some quite nice glass really. One is a 1960's- 1980's Czech handmade Hospodka Chribska vase. The other is I believe an English Wedgwood Sheringham candleholder. The good news is that the more rings, the more collectors want these and a pair is better than a single! Both are decent pieces of glass, not worth throwing away and will cost a few quid to replace, but not likely worth insuring seperately either,
