At Twinkles, we have carefully selected Preciosa® as our crystal of choice — and the reason is simple: quality. For five decades, Preciosa® crystals have been crafted in the Crystal Valley of Bohemia, Czech Republic, the same legendary region where fine crystal-making was born. The local sand is uniquely rich in silicon oxide, giving each crystal its signature depth of sparkle that simply cannot be replicated elsewhere.
What sets Preciosa® flatback crystals apart is their extraordinary optical precision. Each stone is cut to reflect up to 264 unique rays of light — more than any other competing flatback crystal on the market. The result is a brilliance that catches the eye from every angle, making Preciosa® the professional standard for tooth gem artists, dental hygienists, and beauty technicians worldwide. At Twinkles, we select, curate, and package these premium crystals specifically for use as tooth gems, bringing the finest Czech craftsmanship directly to your smile.
All Preciosa® crystals sold by Twinkles are Oeko Tex® certified for safe skin contact and are 100% manufactured in the Czech Republic, EU. They are entirely lead-free — a testament to Preciosa's commitment to blending ancient Bohemian tradition with the most innovative modern technology. From the timeless clarity of Crystal Clear to the ethereal shimmer of Aurore Boreale and the delicate blush of Vintage Rose, our colour range is as vast as your imagination.
