Happy Friday! Today we are featuring five vintage engagement rings with the quintessential sign of vintage wear: oxidation. Oxidation is a chemical process that occurs when electrons leap from the metal and attach themselves to oxygen molecules, and results in a slightly black, tarnished look. Pieces that are made of silver or topped with silver, such as the Whitewater and Broken Arrow rings, tend to oxidize quicker than those made of gold or platinum. Oxidation gives vintage jewelry a truly special antique look! The stones contrast beautifully with the oxidized metal and sparkle boldly. Check out our favorites below! Lake Forest is an incredibly unique authentic Retro era (circa 1945) 14k yellow gold ring centering a bezel set 0.54ct EGL certified Oval Cut diamond graded I color and SI1 clarity. This beauty is further surrounded with an unusual 14k yellow gold floral motif framing the sparkling center stone. Lake Forest is finished with a slightly oxidized finish and a simple tapered shank. The ring is currently a size 6.75 and can be sized to fit. Elysian Park is a fabulous authentic Victorian era (circa 1880) 14k rose gold engagement ring featuring a winning three stone combination of diamonds. This unusual ring centers a 0.78ct EGL certified Old Mine Brilliant Cut diamond graded J color and SI3 clarity flanked on either side by two Old Mine Cut diamonds totaling exactly 0.28ct. Elysian Park is finished with beautiful oxidization to the metal adding to the antique finish on this beautiful, one-of-a-kind ring. The ring is currently a size 6.25 and can be sized to fit. Clarebourne is a charming authentic Victorian era (circa 1875) cluster ring made from silver-topped 14k yellow gold. This gorgeous ring sparkles elegantly, centering an exquisite 0.72ct EGL certified Old European Cut diamond graded J color and SI2 clarity. The ring is surrounded by a delicate halo of nine additional Old Mine Cut diamonds totaling approximately 0.65ct in weight. The contrast between the oxidized silver paired with the bright, white diamond really makes this ring a wow piece!

Broken Arrow is an incredible Victorian era (circa 1880) silver topped 14k yellow gold ring. Our gemology team believes it was originally a brooch that was converted into this stunning ring during the 1940's.

An additional eight Old Mine Cut diamonds surround the center diamond totaling approximately 2.00cts graded I-M color and SI-I1 clarity.
