I ordered an 18k plated necklace. The necklace is lovely, and the engraving is done by hand and lovely, not the generic laser engraving. As much as I love it, the disc is VERY light and thin. I purchased a similar necklace design on Amazon for 1/6th of the price, (although not engraved), and the quality felt much better and sturdier. Time will tell, but for $150 I really did expect a bit better quality. If it holds up, great, bit given how they send directions to not even get it wet, I have serious concerns that it won't last. They don't list the materials the necklace base is either (I would expect solid sterling for the price), which is unusual. If it doesn't hold up I will try and update my review as well.
