Spinel for many years has gone unnoticed as a gemstone if great durability and intense color. In recent years the famous red and vivid pink Spinels from Mahenge, Tanzania and Burma have had all of the glory of the beauty of Spinel. Now people are starting to notice the more pastel colors including the beautiful blue Spinel. The blue Spinel is colored from the impurity of Cobalt in the crystal lattice. These stones are commonly referred to as Cobalt Blue Spinel.
In many locations such as Sri Lanka, the Spinel will have a high iron content which tends to make the stones darker. This makes the stones look blue-gray to violet-blue in color instead of just the pure blue. If the blue Spinel has a high iron content and looks dark in color, it is best viewed in daylight (Specifically sky light where the sun comes from over your shoulder and you cast a shadow over the stone). This will bring out the bright sparkles of blue color in the blue Spinel. Like all Spinel these stones should be eye clean and free from inclusions.
If the stone has visible flaws it will reduce the price. The more vibrant the color the higher the price will be. High saturation in color with a medium tone are the most expensive type of blue Spinel. These are always colored by Cobalt and are extremely rare to find.

The stone is too dark compared to photos. Anyway, the seller is responsive and willing to sort that out. Discussions on refund or discount ongoing.
Perché gli utenti superano se stessi?
Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
