How do I care for my ring?

Clean the piece gently using warm soapy water and a soft brush to remove everyday oils from beneath the stones. Avoid harsh chemical cleaners and ultrasonic baths, particularly if the sapphire has natural fracture fillings. Have a professional jeweller inspect the claw settings and millegrain work periodically to ensure the diamonds and sapphires remain securely anchored.

Are these rings suitable for daily wear?

Platinum and 18ct gold mountings provide sufficient durability for regular use when maintained properly. Sapphires possess high hardness ratings on the Mohs scale, making them resilient against scratching during normal activities. Removal during heavy manual tasks or sports prevents unnecessary impact damage to delicate claw settings or calibré-cut side stones.

How can I identify an authentic period piece?

Examine the construction methods for hand-finished details such as open-work under-bezels and subtle tool marks associated with interwar bench jewellers. Hallmarks and metal stamps provide additional chronological reference points. Compare the stone cuts against historical standards, noting the presence of old European or transitional cut diamonds rather than modern brilliant cuts.

What affects the value of a sapphire?

Geographical origin heavily influences desirability, with Ceylon, Kashmir, and Burmese stones holding distinct positions in the market. The presence or absence of thermal enhancement also alters valuation significantly. Depth of colour saturation, transparency, and freedom from prominent inclusions dictate the visual impact and standing of the central gem.
