Blue Baguette Tennis Chain, 6mm to 9.5mm in S925

Baguette is a step cut, not a brilliant cut, and that changes everything about how this chain behaves. A brilliant has dozens of small facets that chop light into sparkle. A baguette has a few long parallel facets, so it returns light in broad flat sheets instead. Set in a row the effect is a mirrored band that flashes all at once when you turn, which is why baguette tennis chains look heavier and more expensive than the stone count suggests.

You choose between moissanite and zircon here, and the honest difference is this. Moissanite is harder at Mohs 9.25 against about 8.5, so it keeps its polish and its sharp baguette edges through years of wear. It also has a higher refractive index near 2.65, which means more fire. Zircon is softer, flatter in its return and will haze slightly over time, but it costs a fraction as much and is a sound choice for a gift or a layering piece.

Width sets the character. The 6mm is wearable daily and still fits under a collar. The 7.5mm is the middle ground and the most ordered. The 9.5mm is a full statement band and should be the only chain on the neck. Lengths cover bracelets at 7 inch, 7.5 inch and 8 inch and necklaces from 16 inch upward, so you can match a set. The gradient blue runs light to dark along the row rather than sitting one flat tone.
