Millegrain Sapphire Diamond Ring: Frequently Asked Questions
How do I date these rings?
Dating relies on material combinations, gemstone cuts, and design motifs visible in the mount. Edwardian pieces often use platinum and softer floral curves.
Art Deco examples lean towards geometric layouts, calibre cuts, and sharp lines. Later pieces from the mid twentieth century show heavier yellow gold settings.
Are synthetic stones common?
Synthetic sapphires appear in certain period pieces alongside natural stones. Makers utilised synthetic corundum in high precision settings during the early twentieth century.
Every piece listing notes the specific materials recorded for that ring.
Can I wear one daily?
These rings suit daily wear provided the platinum or gold settings remain secure and the prongs hold the stones firmly. Regular checks by a jeweller help protect the millegrain edge.
Removing the ring during heavy manual work prevents unnecessary wear to the delicate metal bead-work.
