Pat Pend For Sale on 1stDibs

Find the exact pat pend you’re shopping for in the variety available on 1stDibs. Each design created in this style — which was crafted with great care and often made from gold, base metal and silver — can elevate any look. Find an antique version now, or shop for 147 vintage or 4 modern creation for a more contemporary example of these cherished accessories. Making the right choice when shopping for a pat pend may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 19th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. A pat pend from Alfred Philippe for Trifari, Trifari and Deutsches Reichs Gebrauchs Muster (D.R.G.M.) — each of whom created a beautiful version of this treasured accessory — is worth considering. A pat pend can be a stylish choice for most occasions, but diamond rings, from our inventory of 11, can add a particularly distinctive touch to your look, day or night. A round cut version of this piece has appeal, but there are also baguette cut and brilliant cut versions for sale. When shopping for a pat pend, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a Pat Pend?

On average, a pat pend at 1stDibs sells for $775, while they’re typically $31 on the low end and $30,000 for the highest priced versions of this item.
