8mm Moissanite Cuban Chain
Price range: $515.00 through $690.00
8mm is the width most people mean when they say they want a Cuban but do not want to shout. There is enough face on each link to catch light from across a table, and it still tucks under a collar when you need it to.

Choosing a length
16in is a true choker on most necks. 18in sits at the collarbone. 20in is the most ordered length in this width and the one to pick if you are unsure. 22in and 24in sit over a t-shirt. If you are between two sizes on an 8mm, take the longer one.
About moissanite
Moissanite was first identified in a meteorite crater in 1893 and is grown in a lab today. It is harder than almost any stone except diamond, which matters more than it sounds on a chain you wear daily rather than for occasions.

Moissanite, answered
Is moissanite a real gemstone?
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.
Will moissanite pass a diamond tester?
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.
How durable is moissanite for everyday wear?
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.
Does moissanite look different from a diamond?
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.
What are the shipping, return and warranty terms?
US orders ship free and every order is tracked door to door. If a piece is not right you have 30 days from delivery to return it, and every Amison piece carries a 12-month warranty against defects in materials and workmanship.
