Comment: So far the deepest blue we have seen from Montana. Especially yummy in full daylight. Definitely not comparable in character or appearance with other mines, even if the color strength does any origin honor. While a silky area becomes visible in some angle and light, it often disappears under the lens, so we settled on a "lightly included" as compromise grade. Obviously a shape that asks for individual design and taste when set in jewelry. Serious size untreated blue sapphire for not too much dough. Great for a gent's ring.
Ask a question.
