The Coronation Pendant

No, and we will never call it one. Moissanite is its own gemstone, lab-created silicon carbide, with more fire than a diamond (dispersion 0.104 against 0.044) and a hardness of Mohs 9.25. It is graded to the maker's standard rather than independently certified, and it is named as moissanite everywhere it appears on the site.

The stone does not. Moissanite is lab-created silicon carbide, chemically stable at Mohs 9.25, and it does not haze, yellow or degrade with time. What people call cloudy is almost always a film of skin oil, lotion or soap sitting on the facets — five to ten minutes in warm soapy water and a soft brush underneath the stone brings it back. The clouding people fear comes from cubic zirconia, which is far softer.

A jeweller will know. Moissanite is doubly refractive where diamond is singly refractive, and a combination tester identifies it immediately. Day to day the tell is fire: dispersion of 0.104 against a diamond's 0.044 throws more rainbow, most obviously in sunlight and in larger stones. Our own guide puts it plainly — if you or your partner specifically want a diamond, buy a diamond.

Two materials, and only two: solid 925 sterling silver and lab-created moissanite. Every piece, without exception. No gold vermeil, no gold-fill, no plated brass, no unnamed alloy.

It can, slowly, with exposure to air and skin. That is the metal living, not a fault — silver reacts with trace sulphur in ordinary air, and every sterling piece from every house does it. A soft polishing cloth brings it back to bright in seconds.

We will not make a claim about how your skin reacts, because no page of ours publishes one. What we do publish is the make-up: solid 925 sterling, 92.5% pure silver alloyed for strength, never a plating over something cheaper, with a platinum finish over the solid silver. Silver darkens by reacting with air, and that polishes back. If you have reacted to silver before, write to hello@maisonnoctaura.com before you order.

Take sterling off before showering, swimming, exercising or sleeping. Chlorine and humidity speed tarnish, a hard knock can chip any gemstone, and prongs bend long before stones fail. Fine chains also kink and stretch under a sleeping body's weight.

Maison Noctaura is the trading name. The business is Maison Noctaura LLC, registration number 42-4033580, and the person responsible for what is published is named on the site: Lee Kung. The full registered details, including the postal address, are published in full on our legal notice at maisonnoctaura.com/policies/legal-notice - published so they can be checked rather than taken on trust.

There are none published, and we will not invent any. What we can put in front of you instead is checkable: the company is Maison Noctaura LLC, registration 42-4033580, with a named person responsible for the site, the registered details in full on our legal notice at maisonnoctaura.com/policies/legal-notice. Every order also carries a 7-day Arrival Guarantee for a piece that arrives damaged, defective or wrong; we do not take change-of-mind returns and do not pretend otherwise.

We cannot speak for another listing. We can tell you exactly what ours is: solid 925 sterling silver and lab-created moissanite, named as what they are, with single pieces at $99–$395 and suites at $425–$1,036. Our own guide also says be wary of anyone charging near-diamond prices for moissanite — the material does not justify it.

Our pieces are selected for Maison Noctaura and produced by our supply partner, and some travel from overseas. We do not run a workshop or a domestic warehouse, and we would rather say that than imply one. Orders typically ship within 1-3 business days and travel tracked.

Orders typically ship within 1–3 business days, and in the U.S. delivery is typically about 5–8 business days counted from when you place the order — that preparation sits inside the window, not added to it. Those are estimates rather than guarantees, and we quote the total rather than a flattering best case. Outside the U.S. the published windows are U.K. 5–8, Europe 4–10, Canada 7–10, Australia 5–10 and elsewhere 7–14, counted the same way. Tracking goes out the moment it ships.

We do not take change-of-mind returns. If a piece simply is not what you hoped for, or the size or style was ordered in error, we cannot take it back — a piece cannot be resold once it has shipped, and we would rather tell you that before you buy than after. What we do cover is arrival: a piece that turns up damaged, defective, or not the item you ordered is a free replacement, or a refund where we cannot replace it, when you email hello@maisonnoctaura.com within 7 days of delivery. There is nothing for you to pay. Whatever cancellation rights the law where you live gives you are unaffected.
