Moissanite Tennis Chain

Yes. Moissanite is silicon carbide (SiC), a distinct mineral first discovered in the Canyon Diablo meteor crater in Arizona in 1893. It is not a diamond simulant and not a substitute — it is its own stone, with its own hardness and its own optical behaviour.

Most common diamond testers read thermal conductivity, and moissanite registers as diamond on those. Testers that also measure electrical conductivity will correctly identify it as moissanite. We are upfront about what our stones are: silicon carbide, not diamond.

Moissanite scores 9.25 on the Mohs hardness scale, second only to diamond at 10. That puts it well above the stones used in most fashion jewelry and makes it suitable for daily wear, including chains and bracelets that take knocks.

It has more fire. Moissanite has a refractive index of 2.65 against a diamond at 2.42, so it throws noticeably more rainbow flashes in direct light. Some people prefer that look — it is the reason we build with it rather than around it.
