    <description><![CDATA[We finished setting the last of the summer aquamarine drop earrings on Tuesday. Twelve pairs, all from the same Minas Gerais parcel, all on 18-carat yellow gold wire. They are in the collection now. When they are gone, this run is retired.]]></description>

    <description><![CDATA[In May we drove down to Estremoz to visit the family lapidary we have been buying pink chalcedony from since 2019. They had a new parcel of material that is softer in colour than anything we have seen from them before. We bought the lot.]]></description>

    <description><![CDATA[Most people who come into the atelier have heard the word chalcedony but are not entirely sure what it is. That is fair. It sits in a confusing part of the gemstone world, related to agate and jasper, sometimes sold under other names, often misidentified. This is a plain account of what chalcedony actually is, how it forms, and why we have built an entire studio around it.]]></description>

    <description><![CDATA[The word bespoke gets used loosely in jewellery. Sometimes it means choosing a stone from a pre-set menu. Sometimes it means picking a metal colour. At Authentic Chalcedony, bespoke means we design the piece from a blank page, with your stone, your brief, and your approval at each stage. Here is what that process actually looks like.]]></description>

    <description><![CDATA[Sterling silver tarnishes. This is not a flaw in the metal; it is a chemical reaction between the silver and sulphur compounds in the air, and it happens to all sterling regardless of quality. The question is how to manage it without damaging the stone it is set with, because most cleaning methods that work well on silver are too harsh for chalcedony, moonstone, or labradorite.]]></description>

    <guid>https://authenticchalcedony.com/notes/moonstone-adularescence-explained.html</guid>
    <description><![CDATA[Adularescence is the word for the floating, billowing light inside a moonstone. It is the quality that makes the stone worth wearing, and it varies enormously from stone to stone. Some moonstones have a strong, high-sitting blue flash. Others have a diffuse, milky glow that sits deep in the stone. Neither is wrong, but they are different, and knowing what you are looking at helps you choose the right piece.]]></description>

    <description><![CDATA[Labradorite is one of the most visually dramatic stones we work with. The labradorescence, that sudden flash of blue-green or gold from inside a dark stone, is unlike anything else in the semi-precious range. But labradorite is also softer and more cleavage-prone than chalcedony or aquamarine, and it rewards a little understanding before you commit to wearing it every day.]]></description>
