Every piece is completely unique in this shop and therefore while there may be two pieces that are similar, there is only one of this design/style/etc. It should also be noted that the hardware on these pieces have only been colored to look like gold, silver, etc. and will degrade over time into copper as they are not made of real gold, silver, etc. The tarnished hardware should not hinder the beauty of the pieces, as it is in the back of the necklace and generally unnoticeable except for when examined closely. Any necklaces with chains have also been plated or colored, which means with more use comes more degradation. As my business picks up, I will happily invest in higher quality materials to make products whose beauty will continue to hold up and that will stand the test of time.
