A 14 karat gold plated 925 sterling silver 1.5mm round tubing open cuff bracelet featuring two rainbow moonstone settings measuring 4mm and 5mm. Inside diameter approximately 60mm.

This cuff is formed from 1.5mm round tubing — a metal tube with a circular cross-section whose outer diameter measures 1.5mm — bent into the open cuff form. Round tubing produces a cuff whose profile at the wrist is a circle rather than a flat rectangle: where a standard flat band cuff presents a wide, planar surface at the wrist, a round tubing cuff presents a narrow, fully rounded wire-like profile whose circular cross-section catches and reflects light from all angles around its circumference. At 1.5mm, the tubing diameter is fine enough that the cuff reads as a delicate, linear element at the wrist rather than a substantial band, directing visual attention to the two moonstone settings rather than the metal itself. The cuff is set with two rainbow moonstone stones measuring 4mm and 5mm respectively. Rainbow moonstone is a variety of labradorite — a feldspar mineral — that exhibits adularescence combined with spectral colour play. Adularescence is the optical phenomenon in which light entering the stone is scattered by alternating feldspar mineral layers within the stone body, producing a floating, billowing glow that moves across the stone surface as the viewing angle or light source changes. In rainbow moonstone, this adularescent glow is accompanied by spectral colour play — patches of blue, violet, and occasionally other spectral colours — producing the rainbow effect for which the variety is named. The two stones measure 4mm and 5mm: the pairing of two different sizes on the same cuff produces a scaled two-stone composition in which both stones share the same material and optical character while differing in dimension. The 5mm stone presents a larger adularescent surface than the 4mm stone, and the two stones together create a varied rather than matched stone arrangement on the fine tubing cuff. The 14 karat gold plating provides a warm yellow gold surface over the 925 sterling silver base. The inside diameter of the cuff is approximately 60mm, and the open back allows the cuff to be placed on and removed from the wrist directly.

A refined natural gemstone cuff for anyone looking for a rainbow moonstone tubing cuff bracelet in 14 karat gold plated sterling silver — two rainbow moonstone stones at 4mm and 5mm on a fine 1.5mm round tubing gold plated cuff with approximately 60mm inside diameter.

✨ How to Wear

Place on the wrist through the open back of the cuff. The inside diameter is approximately 60mm. Do not over-bend the tubing cuff. The 14 karat gold plated rainbow moonstone tubing cuff pairs naturally with yellow gold and mixed-metal jewelry. The adularescent glow of the moonstone is most visible in directional light or when the cuff moves at the wrist.

💎 Quality & Certification

• Genuine Rainbow Moonstone: The stones are genuine rainbow moonstone, a variety of labradorite feldspar exhibiting natural adularescence and spectral colour play.

• Natural Stone Variation: As natural gemstones, the exact adularescent glow colour, spectral colour play intensity, and precise dimensions of each stone will vary between individual pieces.

• Verified Authentication: We are committed to transparency and high-quality standards. Every piece is sourced exclusively from trusted professional suppliers who meet our strict quality and material standards.

• Premium Materials: We partner only with reliable professional suppliers to ensure every piece meets our strict material standards (e.g., genuine .925 Sterling Silver).

⚠️ Important: Size & Scale Disclaimer

• Natural Stone Variation: Rainbow moonstone is a natural gemstone. Adularescent glow colour, spectral colour play, and exact stone dimensions (4mm and 5mm) will vary between individual pieces.

• Approximate Dimensions: Inside diameter is approximately 60mm. Slight variances are inherent to the round tubing cuff production method.

• Plating: This cuff is 14 karat gold plated over .925 sterling silver. Gold plating may wear over time with regular use.

• Macro Photography: To showcase the rainbow moonstone adularescence and round tubing cuff detail, images are taken with macro lenses and may appear larger than life.
