Styling Advice
Our East-West Emerald Cut Button Back Ring adds a contemporary new dimension to our iconic Button Back design.
A literal twist on a classic solitaire, it features elegant emerald-cut diamonds, sapphires or emeralds set horizontally in our signature Georgian cut-down setting. Every stone is chosen for its perfect proportions: neither too wide nor too narrow, and set on a slender gold band to accentuate its sophisticated silhouette.
Choose from blackened or white gold for an antique-inspired or contemporary look. The perfect modern engagement ring, the East-West Diamond Button Back is beloved by cool brides for its pared-back, non-traditional aesthetic. But we also love it worn on any finger, whether as a less-is-more cocktail ring, or paired with denim and trainers to elevate an off-duty look.
Stack it with our signature Bamboo, Rope or 3mm Wire bands, pair it with your Gypset Hoops and a Ball n Chain: it’s the classic-with-a-twist you’ll wear forever.
Delivery & Returns

The Hands-on Method
- Grab a tape measure, length of string or strip of paper.
- Wrap it around the finger you’ll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
- Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest Tiffany ring size.
Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm)
- Use the measurement chart above to match the size of your ring to the closest size in mm.
