I bought a platinum ring for my partner. She wears a 7.5 so I bought a 7 and we are having it resized. The jeweler had never heard of Mene so did a little web research and found it. Where he didn't doubt the rings authenticity (after seeing the website anyway) he pointed out that the platinum ring is inscribed "24k". Platinum is labeled in "fineness" and this, if done by standards, would be inscribed fineness 1000 or simply 1000. He reasoned that the manufacturer process for the gold ring (which was not a realistic choice for an everyday ring as it would be beat to hell in a week it being so soft) was not changed for the platinum version. Apart from that its been a 5 star experience, the ring is beautiful and everyone is happy.
