With 14 dazzling of a total of 0.14 Carat coloured gemstones encrusted in 18 Karat Gold, our Rainbow Lightning Bolt Ear Studs steal the show. A real eye-catcher, we at Culet Jewellery love these sparkling-coloured gemstones. These earrings are available as single earrings or as a pair in yellow gold, white gold and rose gold colours. Pair this beautiful earring with our other rainbow collection items! The gemstones are ruby, amethyst, blue sapphire, tsavorite, yellow sapphire and orange sapphire. Available in yellow gold, white gold and rose gold colours.

With an eye for quality and luxury jewellery, we choose 18 Karat Gold (instead of 14 Karat) with rich colour and high quality. Our ethical and natural diamonds come from responsible sources. Our durable materials can keep sparkling for years.

We exclusively use solid 18 karat gold, because we believe jewellery should be an investment. 18 karat gold is the purest form of gold still suitable for daily wear: it is 75% pure gold. We love it for its rich, beautiful hue. It is extremely unlikely to cause allergic reactions due to the low alloy to gold ratio. All gold used in our jewellery is 100% RJC COC recycled gold. Since our jewellery is hallmarked at Waarborg Holland, Europe's Assay Office you can be assured of the quality and authenticity of our 18 karat gold jewellery.

We only use real, natural diamonds, never synthetic (also called lab grown) diamonds. We believe in jewellery as an investment, and real, natural diamonds are rare and hold their value better then lab grown. Moreover, the natural diamond industry supports communities and economies around the world. Our natural conflict-free diamonds are purchased from suppliers who are certified according to the Kimberley Process.

At Culet Jewellery we only use reputable sources for our jewellery. Our production facilities are audited RJC-member facilities. All elements of our items of jewellery are sourced from reputable suppliers that we have longstanding working relationships with. We work closely with our suppliers when creating our jewellery to ensure that our jewellery is produced in a way that meets our ethical standards and high labour standards. Repairs and adjustments take place in our own atelier.
