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

The expertise of a gemologist in Angers could prove invaluable if you need a precious or fine stone appraised. Beyond the knowledge of a gemstone professional, however, you can also benefit from bespoke jewellery creation.
A gemologist is a specialist in precious and fine stones, known collectively as gemstones, who regularly travels to source them in the countries where the mines and markets are located, and analyses them to assess their quality and value.
The profession, which relies on a wide range of technical equipment, demands broad knowledge of mineralogy, strong negotiation skills, and a thorough understanding of the precious stone market.
Confusion is easily made, for instance between an orange sapphire and a spessartite garnet. Some stones carry names that suggest a specific origin, yet can in reality be found in several parts of the world, as is the case with Paraiba tourmaline.
Pricing can sometimes be difficult to understand — an Australian black opal, for example, may cost more than an emerald. Then there is the matter of imitation stones. In this particularly complex world, the guidance of an expert is indispensable.
The specialist knowledge of gemologists has traditionally been of great value to jewellers and fine jewellery houses, though they also offer their services to private clients. The primary service is, of course, stone appraisal. We are able to assess precious stones in Angers, in the same way as through our precious stone appraisal service in Paris.
But that is not all — Maison Bonnot designs and produces its own fine jewellery pieces, one-of-a-kind creations, using stones sourced directly, without any intermediary. As a gemologist in Angers, we are able to seek out a stone that meets very specific requirements. The stones featured on our website may be purchased by collectors, or used as the centrepiece of a bespoke jewellery creation.
You may call upon a gemologist to identify a stone or establish its value, to obtain a certificate of authenticity, or to receive guidance on choosing a precious stone for a jewellery creation. With Maison Bonnot in Angers, you can also have the jewel of your dreams brought to life.
A gemologist can assist you with many aspects relating to precious and fine stones. They are a professional with deep knowledge of gemstone cuts. They are equally well-versed in the various treatments applied to gemstones — those that are entirely acceptable, such as heating sapphires, and those that diminish a stone's value.
Furthermore, gemologists are familiar with the metals used in jewellery making, manufacturing techniques, the evolution of styles, and the history of jewellery across different periods. It comes as no surprise, then, that many gemologists develop a passion for fine jewellery and that a great number are qualified to appraise jewellery as a whole.
Examples include: the authenticity of the gold, the quality of the setting, and the originality of the design.
Founded by a gemologist, Maison Bonnot Paris brings together a range of expertise and offers various services in Angers relating to precious stones and jewellery creation. If you need to have a precious stone appraised in Angers, whether set in a piece of jewellery or not, please do not hesitate to contact us for a quote.
