Filigree ring handcrafted in our Barcelona atelier using techniques inspired by Berber jewelry traditions from the Great Kabylia tribe of North Africa. Each piece features multiple textures and 3D layering that catches light from every angle.
Our artisans shape precious metal without molds, ensuring no two rings are identical. The seamless construction with invisible solder joints reflects master craftsmanship designed to develop character alongside your story.

Q: How do I care for my tanzanite ring?
Clean with warm soapy water and a soft brush only. Avoid ultrasonic cleaners, steam cleaning, and sudden temperature changes. Remove before gardening, gym workouts, or household cleaning. Store separately from harder gemstones to prevent scratching.

Q: Is tanzanite durable enough for daily wear?
Tanzanite ranks 6.5-7 on the Mohs scale, softer than sapphire but suitable for engagement rings with mindful wear. The bezel setting holds the stone securely and provides protection around its edges. Minor scratches can be professionally repolished without weight loss.

Q: What if my ring doesn't fit perfectly?
We offer complimentary resizing up to one full size. Beyond that, resizing is available for a small fee. Every ring is made specifically for you, and we are always here to help ensure you receive exactly what you dreamed of.

Q: Can I personalize this ring?
Choose from 18K yellow gold, white gold, rose gold, or sterling silver. Add professional engraving or upload your own handwriting for initials, dates, or meaningful words inside the band. Please specify your preferences in the ""note to seller"" at checkout.

Q: Is this ring suitable as a gift or for a proposal?
This ring is perfect for engagements, December birthday celebrations, 24th wedding anniversaries, or as a meaningful self-purchase. The rare tanzanite symbolizes transformation and new beginnings, making it ideal for milestone moments.

Q: How does tanzanite compare to sapphire?
Both display blue hues, but tanzanite offers unique trichroism with blue, violet, and burgundy flashes from different angles. Tanzanite is 1000 times rarer yet more affordable than comparable sapphires.
