there is no such thing as a Ruby Quartz lens sold by Oakley. They made a very limited number for the X-Men movies, but they're movie props that you can't really go out and buy. STAY AWAY FROM EBAY AUCTIONS FOR RUBY QUARTZ. They are all knockoffs.
As for the color of the Ruby lenses, it's a batch to batch thing. Some are redder than others. There are some who insist that older lenses are redder, but there are 4 Ruby Juliets at my store (all the newest batch) of various redness.
if they're from ebay, odds are more than likely that they're fake. in the respect that they're not Oakley products. for the frames, make sure they're hefty metal. ebay fakes are usually plastic.
retail, check the screws 2 orbital screws (bottom of lens orbitals) and the 2 arms for being stripped. Torx screws should look like stars. make sure the lenses don't rattle when you shake the frame a little. make sure the flex coupler in the bridge above the nose is evenly "tight". recently, a lot of them have had one side fused so that it doesn't flex. they should bend evenly on both sides.
Screws are on the hinges and on the outside-bottom of the orbitals where the frame is held together to hold the lens. Stripped screws would have the head part worn away so that a screwdriver wouldn't be able to remove them, since the star-shaped grips no longer provide leverage.
I believe Global Priority (US$10.50-20) does not provide tracking # or insurance.. Global Express does provide both but at a higher cost like US$29-35. U have to ask the seller to declare/insure the item for much less if u wanna avoid the customs asking for tax charge..
My Black/X-Metal Romeo looks brand new after ten years of one-again-off-again use. You have little to worry about in terms of frame wearage (word?) with the X-Metals.
I believe 15 opens wider... How long the frame will get loose?? It depends on how frequent u wear it.. If it just stays in glass cabinet, never put on, it'll stay tight forever I guess! =)
Send it to Oakley for a 'Tune up' but make sure u leave your old lenses if u wanna get replacement lenses fitted because they aint gonna return the replaced (old) lenses..
Also keep the left arm if it has unique serial # on it that u wanna keep, Oakley might as well change the whole frame if requested?? I've never done it before but that's what people say about it..
