This 14K white gold ring (585 purity) is a perfect choice for a woman who appreciates beauty. Its centerpiece is a natural tanzanite, cut in an oval mixed cut, with an approximate weight of 4.21 ct and dimensions of 11.78 x 9.02 x 5.03 mm. This cut enhances the tanzanite’s depth of color and brilliance. The transparent gemstone shifts between shades of blue and violet, depending on the angle of light reflection. Its official color classification is blue-violet. The gemstone’s authenticity and characteristics are confirmed by an IGI certificate. Tanzanite, a rare variety of zoisite, is found only in Tanzania, giving it its distinctive name. The oval mixed cut combines brilliant and step-cut facets, emphasizing the gemstone’s luster and color saturation. The design is complemented by approximately 50 diamonds, with a total estimated weight of ~0.40 ct, graded VS clarity and G color. Around 30 smaller diamonds encircle the tanzanite, visually enhancing its size, while the remaining diamonds adorn the band. This gold tanzanite ring is particularly suited for women with a romantic soul. It beautifully complements elegant evening wear as well as everyday outfits, adding a touch of brilliance. Its versatile design makes it perfect for wearing with a little black dress, a flowing gown, or a tailored blazer. With no structural or finishing imperfections, this ring guarantees durability and lasting beauty for years to come. detailed specifications: stone type: NATURAL ZOISITE – TANZANITE cut and shape: OVAL MIXED CUT carat weight: ~4.21 ct dimensions: 11.78 x 9.02 x 5.03 mm clarity: TRANSPARENT color: BLUE-VIOLET

This applies not only to gold and diamond jewelry, but also to silver jewelry with natural stones – each product is subject to the same standards of transparency and quality.

INKLUZ collaborates on a permanent basis with the Polish Gemological Institute, which confirms the authenticity of jewelry and identifies the stones used. This independent expert institution ensures that customers receive a product that complies with its declaration – both in terms of materials and gemological parameters.

In the case of jewelry with stones with international certificates, the product is also accompanied by documents from renowned institutes such as the Gemological Institute of America (GIA), the International Gemological Institute (IGI), and HRD Antwerp (HRD Antwerp). These certificates contain precise information about the stones' parameters—including weight, color, purity, and cut—and confirm their natural origin.

This ensures that every purchase at INKLUZ is based on reliable knowledge and verifiable data. The certificate is not an add-on—it is an integral part of the product and a confirmation of its value.
