Black wedding rings with hot pink jewels on them are definitely outside of the norm when it comes to engagement jewelry, but if you're looking for something a little different, DesignMasters on Etsy has it covered.
The 'Classic Angel' ring features feather-like wings that delicately grip a lab-grown pink sapphire. The unusually dark band of the ring gets its coloring from an Italian gray gold matte rhodium coting over a 14K solid white gold. DesignMasters advises that the finish will begin to wear within about four years, but the peeks at the gold base below will only add a vintage effect.
Around the ring are also several smaller pink sapphires for extra embellishment. The unique design comes with a price tag of $2,400, but it seems a small price to pay if you really want a very unique engagement ring.
