Our five stones, side by side
Any ring we make can be set with moissanite, lab-grown diamond, lab-created sapphire, ruby or emerald. The first four are made for a lifetime of everyday wear. Emerald is the one that needs care.
- Moissanite: looks like a diamond, sparkles more, costs a fraction
- Lab-grown diamond: a real diamond, grown in a lab
- Lab-created sapphire and ruby: color made for everyday wear
- Lab-created emerald: beautiful, but chips on a hard knock
The five at a glance
| Stone | Daily wear | Price in the same piece |
|---|---|---|
| Moissanite | Excellent | Our base price |
| Lab-grown diamond | Excellent | Costs more than moissanite |
| Lab-created sapphire | Excellent | Same as moissanite |
| Lab-created ruby | Excellent | Same as moissanite |
| Lab-created emerald | Take it off for work with your hands | Same as moissanite |
Emerald is the exception: it is a brittle stone, lab-created or mined, and a hard knock can chip it.
Moissanite
Looks like a diamond. Sparkles more. Costs a fraction. Moissanite is a lab-created gem that bends light more than a diamond and splits it into more rainbow fire. It is made to last a lifetime of everyday wear, and it costs a fraction of a diamond of the same size. It is not a diamond, and we never sell it as one. The full comparison is in moissanite vs lab-grown diamond.
Lab-grown diamond
A lab-grown diamond is a diamond: the same crystal and the same calm white sparkle, grown in a lab instead of mined. Our shop lists it as Lab-grown diamond, and every diamond we sell is lab-grown. How it is graded is covered in the lab-grown diamond 4Cs.
Lab-created sapphire, ruby and emerald
Our sapphire, ruby and emerald are lab-created: grown in a lab, with the same chemistry as the mined stones. Sapphire and ruby are the same mineral, corundum; red corundum is called ruby and the other colors are sapphire. Emerald is a green beryl. It is more brittle, so it suits a ring worn with some care, or a pendant or earrings. Follow the emerald rules in our care guide.
Questions people ask
Which stone is best for an engagement ring I wear every day?
Lab-grown diamond, moissanite and lab-created sapphire and ruby all handle daily wear well. Emerald chips more easily.
Is moissanite a fake diamond?
No. Moissanite is its own gemstone, silicon carbide, with its own look. It is not sold as a diamond and it is not a diamond.
Are your diamonds natural?
No. Every diamond we sell is lab-grown.
Can I get any ring in a colored stone?
Yes. Every ring can be made with lab-created sapphire, ruby or emerald, at the same price as moissanite.
