Strawberry Quartz Gemstone & Information | Gemopedia by JTV | Gemopedia™

Strawberry Quartz

Strawberry quartz is so named because it has a sufficient number of red hematite inclusions to cause a perceived pinkish to reddish body color. While red hematite ribbons are the primary inclusions in strawberry quartz, some gems also contain numerous colorless fluid inclusions and negative crystals, which only add to their desirability and collectability. Mother Nature needed no assistance when creating these beauties and all are 100% natural with no enhancements necessary!

    KeySeparations
    Refractive index, appearance, birefringence, optic character and optic figure. A bull's-eye optic figure is determinative for quartz; may also show Airy's spiral optic figure and Brazil-law twinning under crossed polarizing filters.
    ClassificationComments
    The hematite included quartz from the Cumbria, England mine was called Scarlet quartz. Some stones have been incorrectly called lepidocrocite quartz because the hematite inclusions are often misidentified as lepidocrocite.
