Brazilian amethyst is among the most vivid of amethysts - the deep purple saturated tones from Brazilian mines are distinct from lighter varieties found elsewhere, and at 7.00ctw in 12x10mm oval cuts, these earrings carry substantial color presence at 0.88" long by 0.45" wide. In 18K yellow gold over brass, the warm metal amplifies the cool purple of the amethyst rather than competing with it - the contrast between warm gold and cool purple is one of jewelry's most successful color pairings. Lever backings for all-day security. At this size, the oval amethyst is the dominant visual element and the gold setting is its frame - the 7.00ctw weight means these are stones that earn their placement. Natural Brazilian amethyst rather than simulant or CZ means real gemstone optical properties: the characteristic deep purple transparency that only comes from genuine mineral material. These earrings represent the color gemstone value proposition at its clearest: real amethyst, real gold plating, at a price that makes the purchase uncomplicated.
