This remarkable antique engagement ring features an newly IGI-certified and inscribed Natural Diamond accented with blue sapphires and diamonds. The centerpiece is a gorgeous I SI1 antique cut diamond. While the IGI certificate classifies it as a circular round brilliant, its proportions and visual character most closely align with a Old European Cut. With a small table (46%), generous depth (60.1%), and a large open culet, this diamond embodies the distinctive charm that sets antique cut diamonds apart from their modern counterparts, and for us who adore them there is simply no comparison to their timeless beauty. The beautifully designed platinum mounting remains in excellent condition. Delicate milgrain, pierced details, and fine engraving showcase expert craftsmanship, while diamond accents and custom-cut blue sapphires bring additional sparkle and a subtle pop of color. Video is available by request. We offer 0% Interest Layaway to help you plan for special occasions such as birthdays, anniversaries and holidays. www.Heritagejewelry.com Newly refurbished, this one-of-a-kind 1920s treasure is ready to begin a new chapter—a ring that carries nearly a century of history and promises a lifetime of admiration and love.

This superb Platinum Engagement or Cocktail ring from the Edwardian to early Art Deco era shows the mastery of gem-cutting and setting that jewelers attained in the early decades of the 20th century. This ring, with its elegant ‘Navette’ shape, is centered on a marquise-cut diamond, which is ingeniously surrounded by seamlessly set calibré-cut emeralds. Bordered by glittering circular-cut diamonds, this is a perfect example of a striking yet wearable early 20th century jewel.

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.
