The first of the engravable silver frames I have found is a Cunill Sterling Silver Plain Picture Frame. At first you might be scared off by the price, but you need to remember that this silver plated frame is covered in high quality sterling silver. The frame also has a high quality backing made out of important African hardwoods and are hand crafted in Barcelona, Spain as opposed to somewhere in Asia. The frames can be rested in a horizontal or vertical way. You can find this frame in a 4x6, 5x7, or 8x10 form factor and of course, the frame can be ordered with custom engraving.
The next frame is a Reed and Barton Sterling Silver Narrow Border Frame. This frame comes in a 5x7 form factor so it is perfect for most standard photographs. This frame is also made with impeccable attention to detail just like the Cunill frame. It is made with 92.5% sterling silver and it is polished to an incredible shine. This frame really shows what makes sterling silver great. This frame may look traditional at first but I find it to be quite sophisticated. The frame has a fine blue velvet back and has a very narrow border. This frame can also be ordered with custom engraving.
A Tizo Sterling Silver Elegant Wood Trim Frame is also a great frame that can be ordered with engraving. Unlike the other two frames this one includes wood as well as sterling silver. The border of the frame is split in two sections. The outer section is made with a dark natural wood border and the inner border is made up of fine sterling silver. The silver, not the wood, is what is engraved on. This frame would make a perfect gift. This picture frame was hand crafted in Italy and the attention to detail really shows.
