This necklace presents beautifully. The millegrain edging to both collets remains crisp and well-defined. The aquamarines are eye-clean throughout, with no wear visible at their facet junctions under magnification. All fittings are secure and intact.
Keeper's Guide to Care
Everyday Wear
Aquamarine · Mohs 7.5–8.0 · Rates highly for durability amongst coloured gemstones, making it well suited to regular wear
Aquamarine is full of spirit but appreciates a gentler touch than a diamond. A soft brush with lukewarm soapy water is all that is needed to keep the stones clear and bright.
A note for this piece specifically: The millegrain collet settings on both aquamarines are original and over a century old. Avoid ultrasonic cleaners — the vibrations can disturb antique settings.
We recommend an annual professional check-up to ensure both collets remain secure and the spring ring clasp retains its tension.
