Ring Size Guide
Image of ring with arrows pointing out the diameter

  1. Choose a ring that fits your finger well.

  2. Measure the internal diameter of the ring in millimeters (mm).

  3. Use the chart to find the closest matching ring size.

Wide rings measure differently due to their fit. If you’re measuring for a wide ring, subtract 0.25–0.50 ring sizes from the measured size for a comfortable fit.

  1. Take a tape measure, a piece of string, or a strip of paper.

  2. Wrap it tightly around the finger where you'll be wearing the ring. It should feel snug to get an accurate measurement. If you're stacking rings, keep in mind where on your finger the ring will rest, and mark where the ends meet.

  3. Place the string or paper strip on a flat surface and measure the length up to your mark with a ruler. Refer to the chart above to find the closest match for your ring size.

I wasn't going to, I didn’t need it but then I remembered I had been looking for an opal ring for a long time and this was the most unique setting I had ever seen. It is 100% the perfect one for my hand to make a statement. The white opal is subtle but oh the setting... and when you catch the light just right the opal reveals itself in all its introverted glory. Just like me.

I loved it even more in person. Obsessed is an understatement. I love how I continue finding unique pieces in Abbott and Oaks. I can’t wait to add more to my collection.

Customer photo review of Vintage 14k Yellow Gold Dimensional Figural Goat Charm / Pendant

I have a vintage charm bracelet with animal charms and needed another charm to fill an empty loop and this adorable goat charm is perfect! I love the fact that it is three-dimensional so it will look good no matter which way the charm is hanging.

Customer photo review of Vintage 14k Yellow Gold Aquamarine Blue Sapphire Diamond Openwork Ring 9.00

I had bought this ring because my grandmother who had passed years prior, she always wore an Aquamarine ring that I loved. My birthstone is Sapphire. When I saw this ring, I immediately knew I had to have it since it has both Aquamarine & Sapphire stones, I saw it as sentimental. It is so stunning in person. I am a repeat customer of Abbott & Oaks due to their wonderful customer service & unique jewelry they offer.

Customer photo review of Vintage 14k Yellow & White Gold Diamond Classic Line Band Ring 8.00

I'd been looking for a vintage 1940s white and yellow gold diamond line ring to add as an anniversary band to my family heirloom engagement and wedding ring set from the 1940s. I'd just about given up on finding a vintage ring and then this showed up! The ring matches my set so well. I wear it with the other two rings for a more formal look and substitute it in with only the wedding band for a more minimal look. It is so perfect, like it was meant to be!

Customer photo review of Vintage 14k Yellow Gold 1.2mm Wheat Chain 18"

This 14 karat yellow gold vintage wheat chain is the perfect length and style to complement the charm holder pendant I previously bought from Abbott & Oaks! It is a substantial chain that I know is strong enough to securely hold the pendant and charms. I am delighted with how it looks!

Customer photo review of Antique 14k Rosy Yellow Gold Botanical Orange Blossom Band Ring 5.00

I was hesitant but so glad I chose to buy. I LOVE my band. It is so beautiful, fits perfectly, and the engraving inside from 1919 makes it even more precious. I wish I knew the stories it held, but we are making new ones to add. I hope it'll be passed to one of my daughters to love too. Great company, fast shipping, exactly as described. Love it!

Fantastic Star Sapphire ring with beautiful color changing and asterism effect. I can’t say enough good things about Abbott and Oaks; this is my fifth purchase, and I look forward to more! I also appreciate that there are always several pieces available that are balanced enough for men too.

Customer photo review of Vintage 14k White Gold 1.77ct Aquamarine Diamond Accented Halo Ring 6.50

I had four rings stolen by a cleaning service employee. All four had significant sentimental value. One was the aquamarine my parents gave me in 1997 to celebrate the birth of my first child. While nothing can ever replace what I had, the minute I saw this aquamarine I experienced such joy. It is vintage 90s and helped heal my heart. My daughter thought is was wonderful as well. It was more beautiful in person than in the photos too! I love it so much and I am a very satisfied customer.

Customer photo review of Vintage 14k Yellow Gold .6cttw Diamond Lovely Open Ornate Enamel Ring 5.00

It was so fun to look at all the beautiful pieces and choose 1 that I just fell in love with. It was a big decision and a rep from Abbott & Oak was there to answer all my questions and with their return policy it took away the concern I had if I didnt like what I chose that I would have to keep it. I can't wait to pick something again in the future and I love my ring!
