18k opal and diamond Maria Tash tiara necklace. Rare oval cut colorful opal flanked with prong set diamonds. Tiara is completely closed back, meaning no oil or dirt can cover the back or of the setting and occude the ideal cut diamonds. Low profile and flat against the skin. Opals vary in color, and have a red, blue, and green flash. We normally pair red flash opals with rose gold and blue and green with white and yellow gold. All colors of gold are nickel free and hypoallergenic. White gold is specially alloyed with palladium instead of nickel to maximize the hypoallergenic properties of that color.
Over the course of time, body oil and skin products can collect on jewelry and leave a residue which can occlude stones. To keep your jewelry looking bright and new, take a soft headed toothbrush with some mild soap and gently brush the front and back of the stones and metal. Rinse thoroughly with tepid water. We do not suggest putting jewelry in an ultrasonic to clean. Steam cleaning works well, but do not steam emeralds or opals as high heat can damage these stones.
