About This Piece

Seraphina offers a contemporary interpretation of the classic three-stone ring, balancing the softly defined proportions of a cushion cut with the distinctive geometry of trillion-cut side diamonds. An approx. 1.78 carat cushion-cut diamond forms the focal point, framed by two trillion-cut side diamonds totalling approx. 0.61 carat. Their tapered triangular silhouettes naturally draw the eye towards the centre stone while creating a graceful transition into the polished band.

An open gallery beneath the diamonds brings a sense of lightness to the setting, while allowing the three principal stones to remain beautifully prominent from every angle. Expertly crafted in Australia and available in your choice of premium gold or platinum, Seraphina combines considered proportions, distinctive geometry and understated contemporary elegance.

A: You can refer to our Size Information guide and downloadable printable ring size chart. We also provide Complimentary Free Ring Resizing within 30 days of delivery to ensure a perfect fit.

Q: Can I add custom engraving to my ring?
A: Yes! We offer complimentary custom laser engraving on our rings and wedding bands. You can enter your personal inscription directly above before adding to cart.

Q: Can I customize this ring design or choose a different gemstone shape?
A: Absolutely! We specialize in bespoke fine jewellery and custom commissions. Please click "Book A Consultation" to speak directly with our Master Jeweller.

Choosing the right ring size is important for a comfortable and secure fit. For the most accurate result, we recommend having your finger professionally measured by a jeweller.

Measure a Ring That Already Fits

If you have a ring that fits comfortably:

Choose a ring worn on the same finger and hand as your new ring.
Measure the inside diameter of the ring from one inside edge to the other at its widest point.
Compare your measurement with the size chart below.

Important: Print the guide at 100% / Actual Size. Do not select "Fit to Page" or "Scale to Fit". Check the 50 mm calibration line before measuring to ensure the guide has printed at the correct scale.

Sizing Tips

Measure the specific finger and hand where you intend to wear the ring.
Measure when your hands are at a comfortable, normal temperature.
Your fingers may change slightly in size throughout the day.
A properly fitted ring should slide over your knuckle with slight resistance and sit comfortably once in place.
Wider bands may feel more snug than narrower bands and may require a slightly different size.
