Is it really moissanite?
Yes. Every ring ships with its own GRA report and serial number. It lights up a heat tester because moissanite carries heat almost like a diamond does, and you can watch that happen in the tester video further down.
Will 3 carats be too big for my hand?
Three carats reads big from across the table, which is the point. For slimmer fingers or a quieter look, take the 2 carat or the 1 carat. The size video further down shows the 2 and the 3 side by side on a real hand.

The light test
Same ring. Four kinds of light.
You know the moissy that barely sparkles without direct flash. Here is this one in the light you actually live in.
Moissanite is supposed to out-sparkle a diamond. So it stings when the one you bought looks flat and cloudy at the kitchen table and only wakes up in the sun or under a phone flash.
That isn't you, and it isn't your cleaning. A lazy cut lets light walk straight through the stone, and indoors there is not much light to waste.
This one is cut to send back every bit of light a room gives it. Not one of these four clips needed a flash.
Why it throws more fire
A prism, not a window
Hang a clear pane of glass in a sunny window and the light walks straight through. Hang a prism there and it throws rainbows across the whole kitchen. Glass and CZ are the pane. Moissanite is the prism.
- 01
It bends light harder than a diamond
Light that enters the stone turns sharply and comes back out the top, toward you, instead of leaking out the bottom.
- 02
It splits that light into color
About two and a half times the colored fire of a diamond. That is the rainbow you catch on the side of your coffee cup.
- 03
The cut aims it at your eyes
Its GRA report grades the cut Excellent: the facets are angled to send the fire up through the top, even under a plain ceiling light.
It's not a diamond. Here is what it does instead.
| Sparkday moissanite | Diamond | |
|---|---|---|
| Bends light (refractive index) | 2.65 | 2.42 |
| Colored fire | about 2.5x | the benchmark |
| Hardness (Mohs scale) | 9.25 | 10 |
| Heat tester | lights it up | lights it up |
Fair warning: a handheld heat tester is a blunt tool, and a moissanite tester can tell the two stones apart. This one lights up because moissanite carries heat almost like a diamond does. The real proof is your own hand at the kitchen table.
On camera, not in a studio
Unboxed, tested, worn
On a real hand
Two carats or three, on a real hand
Three carats is the size in the videos: a 9.0mm stone that reads big from across the table. If that feels like a lot for your finger, the 2 carat is still plenty of bling. There is a quieter 1 carat too.
"If 3 carats is too big for your finger, it also comes in a 2 carat."From one of our videos
Next to the one you wear now
The upgrade, side by side
"My new ring just blows my old one out of the water."From her unboxing video, at 0:30
She wanted to upgrade the ring she already wore. She holds the old one beside this one in the same window light, and the difference does the talking. Wear it on its own for the anniversary, or stack it with your band the way she does at 0:39.
What makes this one different
Made for every day, not a photo
Held flush between two bars
No prongs to snag a sweater or bend open over time. The stone sits locked between two solid silver walls, so there is no claw to catch and loosen.
A wide, flat band of solid sterling
Stamped S925 inside. Solid 925 sterling silver all the way through, with no base metal under a thin coat waiting to wear through and turn your finger green.
White or yellow, same fire
The white sits right next to platinum and white gold. The yellow gold tone warms up beside a gold wedding band. Same stone, same cut, same rainbows.
Moissanite vs a 3 carat diamond
Same big look. Not the same price.

| Hardness | 9.25 | 10 | Softer, scuffs |
| Lights up a heat tester | |||
| Paperwork in the box | GRA report and serial | [Lab report, extra cost] | [None] |
| Price | $39.99 | about $38,861 on average | [Under $20] |

Questions
Before you take the leap
My last moissy barely sparkled without a flash. Why would this one?
Because the sparkle comes from the cut, not the sun. This stone's GRA report grades the cut Excellent, so the facets send light back up through the top even under a kitchen light. Watch the light test at the top of the page: window, cafe, lamp, lounge. And if it ever looks cloudy at your own table, send it back within 90 days.
Is it real moissanite, or glass at this price?
Real moissanite, with its own GRA report and serial number in the box. It is $39.99 because it is made in a lab instead of mined, not because it is glass. Glass cannot light up a heat tester, and you can watch this one do it on camera.
Can people tell it's not a diamond?
From across the table, people see a big stone throwing white flashes and rainbows. Moissanite does throw more color than a diamond, and plenty of women wear theirs next to real diamonds and get the compliments anyway. Under a jeweler's loupe, a trained eye can tell. At dinner, it reads as a big, bright solitaire.
Testers can be fooled. Why should the tester video mean anything?
You are right that a handheld tester is not a lab. It fills the bar because moissanite carries heat almost like a diamond, which is exactly what that tester measures. Glass and CZ do not. The tester shows you it is not glass; the light test shows you why you would want it.
Will 3 carats look too big or like costume jewelry on me?
A cloudy stone is what reads as costume jewelry; a big stone throwing real fire reads as a statement you chose. If you have slim fingers or want something quieter, take the 2 carat (8mm) or the 1 carat. The size video shows the 2 and the 3 side by side on a real hand.
Will the band tarnish or turn my finger green?
She says it in her video: "It is not gonna tarnish." The band is solid 925 sterling silver, stamped S925, with no base metal underneath to wear through. If it ever looks dull, the polishing cloth in your care kit brings it back in seconds.
Could the stone chip or fall out?
Moissanite is 9.25 on the hardness scale, harder than sapphire and ruby, so everyday knocks do not scratch it. There are no prongs to bend open: the stone sits locked between two bars of solid silver. The warranty card in the box has the number to call if anything ever happens to your ring.
Do I have to keep it spotless for it to sparkle?
Any stone dulls under lotion and soap film. A drop of dish soap, warm water and the soft brush from your care kit, and it is back to rainbows in a minute.
How do I pick my size?
Sizes run from 4 to 10.5. Choose the size you wear now on that finger. If it runs a little big, the clear size adjuster in the box snugs it up, and the 90-day refund covers you either way.
How fast does it ship, and what if I don't love it?
Your ring ships in 1 to 2 days and arrives 5 to 10 days after that. You get 90 days to wear it in your own light. If you do not love it, send it back for a full refund.
