This stunning fine jewelry ring features a 9.92 carat cushion-cut orange tourmaline as its center stone, celebrated for its warm, vibrant hue that ranges from vivid mandarin orange to rich copper tones. The cushion cut is an ideal choice for colored gemstones, as its rounded corners and large facets maximize color saturation and brilliance.
Surrounding the center stone are 2.10 carats total weight of diamonds, likely arranged in a halo or pavé-style setting that amplifies the ring's brilliance and overall presence. The setting is crafted in 18KT white gold, which provides a bright, lustrous backdrop that complements both the vivid orange of the tourmaline and the sparkle of the diamond accents.
Tourmaline rates 7 to 7.5 on the Mohs hardness scale and has no cleavage, making it a durable and wearable choice for fine jewelry. Orange tourmalines are among the rarer and more sought-after color varieties of this gemstone family, and a stone of nearly 10 carats represents an exceptional size for the category.
