i have a filter i just don't have a confirmed ruby to match against and i've read so many different desc. of what they "look" like but i have trouble just trusting that my version of bright red is the same as anyone elses... i'm going to sell some of them and make some rings and earrings from the ones i want to keep but i don't want to misrepresent them when i sell especially bc they are very expensive and there are some really nice stones amongst them. what do they look like to you under a filter bill? just red right? i think i'm going to take a couple to the local jeweler tom. and see if they will help at all. btw thanks for the offer bill! i just need more practice...

Do you believe all the mystery stones have the same identity, or is it a mixture? You are welcome to send me a few of them and I'll ID them for you no charge....a few like 3 or 4.
yeah i have a jadeite filter... that's where I went wrong lol but i'm going to take barbra up on her offer. you are both very generous! thanks! and i read somewhere that for the larger stones if you hold them up to a light look through and see doubling its a quick way to check for rubies? i tried it last night, compared what i thought were the rubies to the garnets i know are garnets, and for the clean stones it seems to work very well. obvious doubling, or fuzzy doubling. i know it's not scientific but have either of you ever tried that?
thanks, i'm sending some off to barbra to have them confirmed. but i think i'm going to get a secondary form of testing so i don't run into this problem again. any suggestions?

Yes.
1. Only buy from a trusted source with gemological expertise and instrumentation.
2. Only buy stones accompanied with identification reports from internationally respected gem labs.
3. Buy a quality polariscope, refractometer, spectroscope, dark field loupe or microscope and enroll in a course to learn how to use them properly. There are no shortcuts to gem identification.
