Aquamarine Straight Drilled Natural Crystals measure approximately 11x13x7mm to 25x18x16mm in size, have a dull luster due to the natural unfaceted state of the crystal, the gem bodies have a rough nugget-like surface produced from natural processes, the crystals have a semi-translucent quality with internal features, and the untreated color shows a greenish blue hue creating an organic Aquamarine in their natural crystal appearance.
