Details
The Nova Ruby Engagement Ring is a stunning tribute to the elegance of the Art Deco period. Featuring four sleek baguette-cut diamonds set along the band, this ring epitomises timeless sophistication. The crisp, geometric lines of the baguettes beautifully enhance the dazzling central Ruby, creating a seamless blend of vintage charm and modern sophistication.
With its eye-catching design and architectural grace, the Nova appeals to those who appreciate the glamour and precision of Art Deco craftsmanship. This makes it the perfect choice for an engagement ring that radiates both class and refinement.

How to measure

1. Grab a tape measure, length of string or strip of paper.
2. 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.
3. 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 Holts & Gems ring size.
