Opals are gorgeous, unique, personal, and hugely popular. In fact, they are one of our top five most popular stones for engagement rings. No other gem features the same shimmering rainbow of colors that you'll find in opal.
Opals display bright flashes of color that change at every angle, with a broad range (and unique mix) of colors represented, and distinctive patterns that range from small pinpoints of color to large rolling flashes. There’s no alternative we can recommend that gives you a comparable look with better durability.
