Blue Sapphire: The Complete Guide (Meaning, Price & Origin)

Sapphire is a treasure for jewellery lovers, and because imitations exist, we are going to look at how to identify a sapphire — from the less reliable methods to the most dependable. We will also cover quality assessment.
A real sapphire can be confused with a synthetic sapphire. A blue sapphire can resemble other stones. Sapphire is an extremely popular stone, particularly for engagement rings.
A gemmologist can sometimes distinguish a genuine sapphire from a blue spinel or a tanzanite, but to the naked eye the resemblance can be striking. A more thorough expert assessment is often necessary. Tanzanite and blue spinel are evocative of sapphire, yet their compositions are very different.
Sapphire comes in a range of colours, each of which can be confused with other stones. It can be particularly difficult, for instance, to tell a pink sapphire from a pink spinel, as the two share a similar clarity and brilliance.
Sometimes a real sapphire can be distinguished from a synthetic one by the presence of slight imperfections, whereas a synthetic stone will have none. Laboratory sapphires are created to be flawless. That said, some natural sapphires also show no imperfections visible to the naked eye.
The most reliable way to identify a sapphire is to seek a professional gemstone appraisal and, if it is a genuine stone, obtain a certificate of authenticity.
Synthetic sapphires are widely produced and are used extensively in the watchmaking industry. The methods for identifying a synthetic sapphire are generally unreliable. The breath test is one such example. You can breathe onto a stone — if the condensation disappears slowly, this tends to suggest a synthetic stone.
Another method (equally hit-and-miss): you could turn off the lights and use a small lamp. The light emitted by certain synthetic sapphires can appear suspicious.
Finally, high-quality natural sapphires contain no air bubbles, whereas imitations may — though not always, and not necessarily in a way that is visible to the naked eye.
It is worth noting that nothing beats a microscope and spectroscopy. Maison Bonnot offers its gemmologist services in Angers.
A good-quality sapphire may be a heated sapphire, but that does not necessarily mean it has been treated. Heating is a traditional and widely accepted practice, considered standard in the trade — unlike treatments that fundamentally alter a stone. Furthermore, a fine sapphire has no inclusions visible to the naked eye; this is certainly true of the vast majority of the highest-quality sapphires used in jewellery. The purity, or clarity, of a sapphire depends greatly on its inclusions, and the most sought-after sapphires — such as Ceylon sapphire — are notably pure. Where inclusions are present, the stone remains transparent.
The colour of a quality sapphire is intense and even. Colour can vary according to the origin of the sapphire, and certain regions of the world produce stones of differing hues. Burmese royal blue sapphire, for example, is highly prized, yet Burma produces sapphires in a variety of shades. Identifying a precious stone is no straightforward matter, but this kind of knowledge can sometimes prove very useful.
