Natural Sapphire Jewellery
Natural sapphire jewellery spans centuries of gemstone craftsmanship, offering durable precious stones set in platinum, gold and silver for everyday wear.
Natural Sapphire Jewellery
Natural sapphire jewellery encompasses rings, necklaces, pendants, brooches, bracelets and lockets originating from periods such as Victorian, Edwardian, Art Deco and Mid-Century. Buyers seeking natural sapphire jewellery will encounter clusters, solitaires, trilogies and line settings spanning blue, pink, yellow and purple stones.
Ring designs range from delicate stacking bands and solitaire mounts to substantial cocktail pieces and multi-stone clusters set with diamonds. These items combine central corundum gems with supporting stones, reflecting the prevailing aesthetic of each decade from the late nineteenth century through to the nineteen-sixties.
Materials and construction
Gems are mounted in metals including platinum, 18ct white gold, 18ct yellow gold, 9ct gold and silver, often paired with diamonds, pearls or aquamarines. Stones display various cuts, from emerald and cabochon to old cut and rose cut diamonds.
Settings utilise claw mounts, bezels and intricate millegrain detailing to secure unheated Ceylon, Kashmir and Burma sapphires. Pearls and diamonds are integrated into floral motifs, geometric Art Deco patterns and Edwardian bows.
Several pieces incorporate secret locket compartments and delicate gold bows designed to pin securely onto historical lapels.
Factors determining quality
Quality rests upon the origin, carat weight and heat treatment status of the corundum, alongside the purity and colour saturation of the stone. Unheated stones from specific regions command distinct interest among collectors.
The precision of metalwork, the matching and cut of supporting diamonds, and the presence of independent gemological reports further distinguish individual pieces across the historical spectrum.
The Natural Sapphire Jewellery Glossary
- Unheated sapphire
- A natural corundum gemstone that has not undergone thermal enhancement to alter its colour or clarity. Such stones retain their geological properties unaltered from the mine.
- Cabochon
- A gemstone cut with a smooth, rounded, convex upper surface rather than faceted planes. This style highlights asterism in star sapphires or deep colour in large stones.
- Millegrain
- A decorative jewellery technique featuring a line of tiny metal beads along the edges of a setting. It provides a soft texture characteristic of Edwardian and Art Deco pieces.
- Trilogy ring
- A ring featuring three principal gemstones symbolising the past, present and future. These commonly pair a central sapphire with flanking diamonds.
- Old cut diamond
- A hand-cut diamond shape predating modern brilliant cuts, featuring a smaller table, higher crown and larger culet. These stones exhibit a softer gleam under candlelight.
Natural Sapphire Jewellery: Frequently Asked Questions
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.
