In my 30 years of collecting vintage jewelry I’ve never seen another ring like this one. It’s a vintage art nouveau Navette, pearl and diamond ring. The diamond is crisp and clear and bezel set with milgrain work. It’s 10 karat yellow gold with a triple split shank. Has graduated round pearls with a teardrop shape in the center. Size 8.5 and fully size able. It does appear a few pearls have been replaced. But it’s still a beautiful piece from the late 1800s. I found a stick pin that's $350. It's the only other piece I've seen remotely like this. I just can't wear pearls. I tend to put my rings on and wear them for months.

Tiffany & Co Platinum Diamond LUCIDA Engagement Ring 2.01 ct H SI1 GIA Cert Size 5.5 This is an authentic pre-owned Tiffany ring which has been freshly cleaned and polished. It comes with the GIA certificate, inner suede and outer cardboard Tiffany boxes. The diamond is laser inscribed "LUCIDA" per the GIA certificate. This is a natural, earth-mined diamond. This is a big, bold, stunning piece. The diamond is eye-clean, bright and white. I bought this secondhand because I wanted something heavy and durable for everyday wear as my original e-ring is more delicate and I found I wasn't wearing it. Now, I am looking to sell so I can pursue another project. For more info or questions please contact me at gemshowgem@gmail.com
