Gemstone composition and care
Enhancement techniques and care instructions
Gemstones are often treated to enhance the color, clarity, and stability of the stone. Heat can improve its color or clarity. The heating process has been well known to gem miners and cutters for centuries, and in many stone types heating is a common practice.
At Hannah's Gemstone Jewelry we use natural, dyed, and heated gemstones stones; which does not take away from the quality of the gems. For example:
Black onyx, carnelian, and some of the red agate have been dyed and heat treated to enhance color.
Our turquoise have been stabilized for strength. Preciosa Ornela Traditional bead in Fire polished Czech glass and glass pearls are used in many designs to add a bit of sparkle and glamor and enhance the gemstones in a particular design.
See the "Extended Information" tab under each product to learn about how to take care of your gemstone jewelry.
