Quartz: Colors
built 264 days ago
Quartz countertops are the new worry-free alternative to high-maintenance granite. They are stronger than granite, require no resealing, are highly resistant to scratches and stains, and come in a huge variety of colors.

Quartz's ability to attract all seven color rays makes it an ideal partner to wear with a color-ray gemstone necklace. The color ray gemstones include Ruby, Carnelian, Citrine, Emerald, Blue Sapphire, Indigo and Amethyst. Not only does Quartz enhance the flow of life force through all levels of your being, it amplifies the effects of the color ray gemstones and balances the proportions of color rays within you.

There are light blue, transparent Quartz crystals in the market. They are not naturally colored, but Rock Crystal (transparent colorless Quartz crystals) synthetically tinted with irradiation of gold. A few dealers sell them as "Blue Rock Crystal", without informing the buyer that these crystals are not naturally colored.
