The atelier

A catalogue you can read before you buy

ThrillGlow is a small atelier working with moissanite. We publish the parameters, photograph the facets, and answer by email.

Why we started with one stone

ThrillGlow began with a simple irritation: jewelry shops describe a stone in adjectives, then ask you to trust them. We preferred the other order — set out the parameters, photograph the facets, and let the piece argue for itself.

Moissanite, measured in facts

Moissanite is silicon carbide, with a hardness of 9.25 on the Mohs scale and a refractive index between 2.65 and 2.69 — higher than diamond, which is why it returns so much light. It is not diamond, and we never sell it as one.

Set by hand, finished slowly

Each claw is closed by hand, each band polished in stages. Small stones are matched for tone before they are set, so a row reads as one line rather than a sequence of different whites.

Made to be worn, not stored

We design for the ordinary day: a band that survives a desk, a chain that survives a coat. Care instructions are included with every order, and questions go to a person by email.

Questions

Anything else goes straight to the concierge.

Contact

Is moissanite a diamond?: No. Moissanite is silicon carbide with a different crystal structure. It is not sold here as a diamond or as a diamond substitute; the stone type is stated on every product page.
How do I choose a ring size?: Compare an existing ring's inner diameter with our size chart, or email the concierge with your usual size. Resizing guidance is available before you order.
Will the plating wear off?: Vermeil is a silver base with a gold layer. Perfume, chlorine and abrasive cloths shorten its life; the care card in each order explains what to avoid.
How does payment work?: You can pay online with Alipay, or submit the order and let the concierge confirm payment and shipping details with you.
Can I change my order after placing it?: Email the order number and the change you need. If the parcel has not been dispatched, the concierge will adjust it where possible.
