New Pt950 Heart Shape Cobalt Spinel Diamond Ring 1.013ct 0.87 Rare Stone Rare Stone [Escole]
Product Description The main piece is set with a 1.013ct heart-shaped cobalt spinel with a beautiful deep and clear royal blue color. Among cobalt spinels, sizes over 1 ct are extremely rare, and it is a very attractive stone with a well-shaped heart shape and excellent color.

What is noteworthy is the bright blue coloring factor. Even spinels containing cobalt are often strongly influenced by iron. However, this is a highly rare type that does not show absorption bands derived from iron, and the coloration due to cobalt stands out.

The accompanying analysis report from the Japan-German Gem Research Institute also reports an absorption band derived from cobalt and the detection of cobalt through elemental analysis. The clear, clear blue color is one of the great charms of this gemstone. In recent years, these high-quality cobalt spinels have been attracting attention in the international market, and even considering the market prices in major jewelry markets such as Bangkok, the beautiful heart shape, which is 1 ct larger, is expected to be highly praised.

A total of 0.87ct diamonds are luxuriously set surrounding the center stone. In addition to the gorgeous halo design, diamonds are also placed on the arms, creating a beautiful contrast between the bright blue of the cobalt spinel and the pure white sparkle of the diamonds. In addition, by using a white base metal, the transparency and dignified beauty of the blue color are further enhanced. Although it has a lovely heart shape, it has a finish with a presence and elegance that is less sweet.

Make rare 1ct up cobalt spinel into jewelry that will last a lifetime. This is a special item that can only be created by Selby, with careful consideration of the value of the gemstone itself, from design to production. We will also attach videos to channels that can be embedded, such as our official online store (prices vary), so we hope you will consider it.
