      FAQs

      Everything you need to know about buying genuine opals and jewellery on our marketplace.

      Yes, our opals are 100% natural. Each product page includes the available details about the opal type, origin, size, and condition. Please check the individual product description before ordering.

      Choose based on the color you like, brightness, size, shape, and purpose. For jewelry, also consider durability and setting style.

      No, rough opal is usually for collectors, lapidary work, or display. If you want a finished piece, choose polished opal or opal jewelry.

      Welo opal usually refers to opal from the Wollo/Welo region of Ethiopia. These opals are popular for their bright color play and beautiful patterns.

      Yes, Ethiopian and Australian opals can differ in appearance, structure, and how they react to moisture. Always follow the care instructions for the specific opal you buy.

      Opal can be worn often, but it needs care. It is softer than many gemstones, so avoid wearing it during the gym, cleaning, gardening, swimming, or heavy hand work.

      Clean opal gently with a soft cloth and mild soapy water. Do not use ultrasonic cleaners, steam cleaners, bleach, toothpaste, or harsh chemical cleaners.

      A quick splash is usually not a problem for many solid opals, but opals should not be soaked. Doublets, triplets, and inlay opals should be kept away from long water exposure.

      We try to show the opal as clearly as possible, but color can look slightly different under natural light, indoor light, and different screen settings.

      Opals naturally vary in color, fire, pattern, brightness, and shape. This is what makes each opal unique and different from standard gemstones.

      Opal fire means the colorful flashes you see inside the stone. These flashes can show colors like green, blue, orange, yellow, and red depending on the opal.
