Moissanite is one of the most popular diamond alternatives in hip-hop jewelry—but that also means plenty of sellers slap "moissanite" on pieces that are actually CZ, glass, or low-grade stones. Here is how to verify a real moissanite stone in under five minutes.
Test 1: The Moissanite Tester (Most Reliable)
A standard moissanite tester uses thermal and electrical conductivity to distinguish moissanite from diamond and CZ.
- **Moissanite** → registers on the moissanite scale
- **Diamond** → registers on the diamond scale
- **CZ / glass** → fails both, no reading
This is the test jewelers use. If a piece is advertised as moissanite but fails a moissanite tester, it is not moissanite.
Test 2: Double Refraction Under Magnification
Moissanite is doubly refractive—light splits in two when passing through the stone. Under a 10x loupe, look through the stone at the facet edges: real moissanite shows **doubled facet lines**. CZ and glass show a single sharp line.
This is the same optical property that gives moissanite its famous fire, and it is the fastest way to spot a fake without a tester.
Test 3: The 925 Hallmark
At Vault Iced, every piece ships with a **925 stamp** on the metal—that is the standard mark for 92.5% sterling silver. If a piece claims to be "925 silver" but has no hallmark, treat it as a red flag.
Note: a hallmark proves the metal, not the stone. You still need tests 1–2 for the moissanite itself.
Test 4: What Doesn't Work
- **Scratch test** — "if it scratches glass, it's a diamond" is a myth. CZ and glass scratch glass too.
- **Fog test** — breath on the stone; diamond clears fast, moissanite clears fast as well. This test cannot reliably separate the two.
- **Price alone** — cheap pieces can still be CZ labeled as moissanite. High prices can still be overpriced CZ. Trust the tests, not the price tag.
Test 5: Buy From Someone Who Can Prove It
The simplest test is the source. A reputable seller should be able to:
- Confirm the stone tests positive on a moissanite tester
- Show you the 925 hallmark
- Offer certificates on request (especially for wholesale orders)
At Vault Iced, we encourage buyers to verify: every piece carries the 925 hallmark, and we will walk you through testing your piece after arrival. Wholesale clients can request documentation with their order.
