What is an unheated sapphire?

An unheated sapphire is a natural gemstone that has not been subjected to artificial heat treatment to improve its colour or clarity. Gem reports verify this untreated status, which is valued by collectors for rarity.

How do I care for antique jewellery?

Antique jewellery requires gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners. Store pieces individually in soft pouches to prevent metal and gemstone abrasion.

How are stone origins identified?

Geographical origins such as Ceylon, Burma or Kashmir are determined through microscopic analysis of internal inclusions by gemological laboratories. These findings are detailed in official certificates accompanying the piece.
