Delivered to Switzerland in 12 days. Perfect customer service, as usual with this seller. Base metal tests as Silver of .900+ purity, the stone's spectrum matches the cubic zirconia (do not confuse with Zircon or Zirconium - these are all different). The luster is nice, the clarity is near perfect. Overall look is what I was looking for for my wife's party outfits. I recommend this item and this seller. I would only suggest adding 1/4 size step options for a better fit.
Thank you!
