This is a really really pretty ring with a large bi-color Tourmaline.... It kind of fades from blue to green and in certain light it looks much more blue and in other lighting it looks very green. It has a 10kt stamp but I wouldn't Give my word that it is solid gold I did acid test it but I did use a magnet and gold as well as platinum is magnetic and this ring didn't seem like it was reacting to the magnet my guesses it is gold plated but it is stamps so and may be sold gold. It is a size 7 and I think I've worn it once it's a little too large for my finger so I've never really worn it. The turn Alene is a 2 carat round cut and it is accented by clear Spinels.
