Celestine Diamond Key Pendant

Celestine draws inspiration from the timeless symbolism of a key, bringing together an elongated sculptural silhouette and intricate geometric openwork.

About This Piece

Celestine reimagines the classic key through carefully considered geometry and delicate openwork. The circular head is shaped with a layered geometric motif that flows into a slender stem accented by subtle sculptural bands, before finishing in a distinctive angular key bit that gives the pendant its refined architectural character.

A single round diamond measuring approx. 1.20 mm and weighing approx. 0.008 carat is secured in a bezel setting at the heart of the design. Its delicate brilliance creates a subtle focal point within the openwork composition while preserving the clean lines and intricate precious-metal detailing that define Celestine.

Crafted with considered proportions and refined finishing, Celestine brings together enduring precious metal, delicate diamond detailing and the symbolism of the key in an elegant expression of possibility, connection and meaningful new beginnings.

Q: What is the difference between Lab Grown and Natural Diamonds?
A: Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are real diamonds created in highly controlled laboratory environments rather than mined from the earth.

Q: What chain options and lengths are available?
A: We offer matching solid gold Cable, Box, and Wheat chains in standard 45cm (18") adjustable lengths. You can select your preferred chain style above.

Q: Can I purchase the pendant without a chain?
A: Yes, you can choose the "Pendant Only" option if you already have your own chain.

Q: Can I customize the design or gemstones?
A: Absolutely! We specialize in bespoke commissions. Please click "Book A Consultation" to customize your piece.

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.
