"Ametrine" Crystal Quartz Round Triplet Faceted Stones


This round triplet is composed of a faceted clear quartz top and bottom; the adhesive that holds the two halves together provides a beautiful two-tone color shading from the purple of amethyst to the gold of citrine—so you can have the look of ametrine at a budget-friendly price. The natural transparency of crystal quartz makes it an ideal alternative to expensive gemstones or CZs.

One of the most common minerals, quartz comes in many varieties and colors. The two main categories are macrocrystalline, which are usually transparent and crystals are visible, and cryptocrystalline, which appear translucent or opaque. The many varieties of quartz each offer distinct characteristics and, according to folklore, their own powers and purposes.

Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
