Opal is a rare and iridescent gemstone known for its play-of-color, the shifting rainbow hues seen across the surface when light hits the stone. This optical effect is created by microscopic silica spheres inside the gem.
Opal value depends on several factors, including color saturation, pattern quality, body tone, clarity, origin, and carat weight. Black Opals from Lightning Ridge, Australia are considered the most valuable, often priced significantly higher due to their rarity and intensity.
Opal has long symbolized hope, creativity, emotional depth, and transformation. Its changing colors are said to reflect the moods and inner truths of the wearer. G Marie believes Opal jewelry is more than beautiful, it’s deeply expressive and full of personal meaning.
Opals can display nearly every color on the spectrum, often within a single stone. Body tones range from milky white and fiery orange to dark gray and jet black, with flashes of green, blue, red, and purple. Black Opals have the highest contrast and are the most prized for their dramatic appearance.
Opal is the official birthstone for October. It is often given as a gift to celebrate birthdays, anniversaries, or moments of transformation. G Marie offers a curated selection of Opal pieces ideal for October birthstone jewelry or personalized milestone gifts.
Opal is one of the rarest gemstones in the world, with Black Opals being the most scarce. True gem-quality Black Opals are found almost exclusively in Lightning Ridge, Australia. Due to their unique formation process and limited supply, these stones are highly collectible and prized in fine jewelry.
