Are these rings suitable for everyday wear?

Sapphire sits at nine on the Mohs hardness scale, making it durable enough for daily use when mounted securely in robust platinum or gold settings. Regular checks by a jeweller ensure the claws remain tight. Care should still be taken during manual labour or heavy lifting to protect antique metalwork and delicate pavé diamond settings from impact.

How can I tell if the sapphire is natural?

Examinations under magnification typically reveal natural internal growth lines, silk inclusions, or colour zoning unique to earth-mined stones. Laboratory certificates often accompany significant Burmese or unheated specimens. Paste stones or synthetic substitutes appear in some period pieces, identifiable by uniform bubble inclusions or lack of natural inclusions.

What is the difference between platinum and white gold in these rings?

Platinum offers a naturally bright, durable white finish that does not require plating and holds tiny claw settings securely over decades of wear. White gold alloys used in the era often contained nickel or other metals to achieve a pale hue. Both metals provide the cool monochromatic backdrop essential for making deep blue sapphires and white diamonds stand out.

How do I determine the correct ring size?

Professional sizing by a jeweller experienced in antique pieces is recommended to preserve delicate shoulders and gallery work. Many rings from this era feature solid shanks that accommodate careful adjustment. Altering size requires caution when millegrain or calibre stones extend far down the band, as excessive stretching can compromise the side channels.
