That frame would be cool in clear lucite, but if you can't find it, you could paint the frame the same color as the wall it's hung on, but in a higher gloss.

Or you could look for a Venetian Mirror:

Here's an expensive one:

and here's a lower price version:

And here's a page from Neiman Marcus that has a number of versions at the bottom of the page:

Another idea would be to paint the frame the same color as your wall to get the grissaille effect without having to shell out for the expensive lucite or mirror version.

Another idea would be to get a laser cutting shop to cut scrollwork into a thick piece of plexi or acrylic. It would be flat, but you could get something with a similar effect using elaborate scrollwork.

Or bribe a skilled sculpting friend to mold it and cast it out of clear resin. ;) Probably be difficult with something that size, but it might be doable.

I'm with Kaete, I'd think you'd be able to cast it in clear resin. It'd be fun to try, at least.

try Tap Plastics... we use them in the photo studio I'm pretty sure they can make anything.

I found this pricey one that could work - http://www.onewayfurniture.com/zuo-modern-850005.html?utm_source=zuo-modern-850005&utm_medium=shopping_engine&utm_campaign=google_base&CAWELAID=608994437
Or look in thrift/antique shops for an ornate metal one, then bring it to an auto paint shop and ask them to chrome it. It wouldn't be clear but I think the chrome frame would give you the same feel, and be a very unique piece!

Did you see TRON Legacy? Jeff Bridges' "safehouse" was top-heavy in awesome design, from a floor that was right out of the finale of 2001: A Space Odyssey, Mid-Century furniture, and ornate, clear furniture cast in clear lucite, like what you are after here. Absolute eye candy. Good Luck! 8^)

Hi Rebecca,
We are a small design shop, and just started making and selling custom cameo mirror frames. We can design/make one for you out of clear or colored acrylic...even wood. Check out our etsy store for an idea of what it could look like. http://www.etsy.com/shop/humanarray
or you can get in touch at www.lasercuttingshop.com

I forgot to mention that Laser Cutting Shop can cut acrylic mirror if you just wanted to have the shape. Good luck with your search!

This tabletop mirror on etsy sounds similar to what you're looking for, and comes flat pack so could easily be converted into a wall mirror. It's a bit small, but very affordable at $30:
