Why This 7.94 Carat Size Matters
Natural Ethiopian Welo Opals above 7 carats with strong play-of-colour are uncommon in the certified gemstone market. This 7.94-carat Welo Opal offers exceptional value for buyers seeking a large, certified stone with impressive fire. The generous 20.2 × 13.3 mm spread ensures the gemstone makes a bold visual statement when mounted in jewellery.Understanding Ethiopian Welo Opal's Hydrophane Property
Ethiopian Welo Opal is classified as "hydrophane" — it naturally absorbs water due to its porous silica structure. This is NOT a defect; it's the very property that creates the spectacular play-of-colour fire you see.What happens if it gets wet: The play-of-colour may temporarily disappear as water fills the microscopic voids between silica spheres. Simply allow the stone to air-dry naturally (24-48 hours) and the fire returns completely. Never use heat to speed drying — this can cause cracking.
Care recommendations:- Remove before washing hands, showering, or swimming
- Apply perfumes and lotions BEFORE wearing your opal
- Clean with soft, dry cloth only — avoid ultrasonic cleaners
- Store separately from harder gemstones (diamonds, sapphires will scratch opal)
- Avoid extreme temperature changes

These are natural identifying characteristics that help gemologists confirm the stone is genuinely natural and distinguish it from synthetic or imitation materials. Such features are normal in natural gemstones and do not indicate defects.Browse More Opal Options

Frequently Asked Questions
This is a 100% natural Ethiopian Welo Opal, confirmed by laboratory certification. The stone is completely untreated — no heat, no dye, no enhancement of any kind. The play-of-colour you see is entirely natural.
Ethiopian Welo Opal is "hydrophane" meaning it naturally absorbs water. When water enters the stone's microscopic voids, it changes the light diffraction properties that create the play-of-colour. This is temporary — once the stone air-dries completely (24-48 hours, sometimes longer), the fire returns in full. Never use heat to speed drying as this can cause cracking.
Ethiopian Welo Opal has a hardness of 6.5 on Mohs scale — softer than sapphire or diamond. For daily wear, we recommend pendants or earrings which are better protected. If used in rings, choose protective bezel settings and remove during physical activities, washing, or swimming. With proper care, Ethiopian Welo Opal can be enjoyed for many years.
The main difference is water absorption. Ethiopian Welo Opal is hydrophane (absorbs water) while Australian Opal is non-porous and water-stable. Ethiopian Welo Opals often display more vivid, three-dimensional fire at significantly lower price points. Australian Opals are priced higher due to their established reputation and water-resistant nature. Both are 100% natural precious opals.
Clean Ethiopian Welo Opal with a soft, dry microfiber cloth only. Avoid water, soap, ultrasonic cleaners, and steam cleaners. If the stone accidentally gets wet, let it air-dry naturally in a safe place — never use hair dryers or heaters. Store separately from harder gemstones to prevent scratching.
Opal is the official birthstone for October. In Vedic tradition, it is associated with Venus (Shukra) and is mentioned as a gemstone option for Libra (Tula) and Taurus (Vrishabha) signs. For specific astrological guidance, we recommend consulting a qualified astrologer based on your individual birth chart.
Ethiopian Welo Opal became commercially available only in 2008, making it newer to the market than Australian Opal which has over 100 years of established trade. Additionally, Ethiopian deposits are abundant and the hydrophane property requires extra care — both factors contribute to more accessible pricing. The beauty and play-of-colour, however, are equally stunning.

Silver, white gold, and platinum are popular choices for opal settings. Traditional recommendations suggest silver for astrological purposes. The choice often depends on personal preference, budget, and desired jewellery style. Bezel settings offer more protection than prong settings for this softer gemstone.
Ratna Gems specializes in loose certified gemstones and does not currently offer custom jewellery services. You can have this stone set by your trusted local jeweller.
