Amazing 930 carat non-hydrophane crystal opal from Ethiopia! This is one of the best specimens of crystal opal that I've come across due to its size and intense play of color. It looks stunning in direct sunlight and in direct view of lamp/overhead lighting. The weight may not be exact as it does have to stay moist when on the scale, but will be close.
This particular opal does need to be stored moist to keep it from crazing, so we recommend a clear jar or dome filled with water. They make amazing display specimens, but are not suitable for jewelry. We consider this piece to be a Small Cabinet (SMC) mineral specimen.
*This piece will be shipped wrapped in moist paper towel and you will need to refill the glass display jar with water upon receiving the opal. THIS PIECE MUST REMAIN MOIST, if not, IT WILL craze. We suggest using distilled water.
Weight: 940 carats
Measurements: 77.4mm x 71.3mm x 35.1mm
Locality: Ethiopia

I don’t have enough time or words to share the joy I have found in this incredible “hidden gem” (pun intended) shop. The quality of the products, the love that goes into the creating, and the extremely personable staff are all a part of why I love it so much. They are able to take the little bit of information you give to them, and with their vast amount of knowledge, bring to life a creation of what’s in your mind, working until it’s to perfection...
I was looking for a bicolor sapphire for an engagement ring and fell in love with a gem I found on their website. It is so beautifully cut and the blue/green and yellow hues are exactly what I had envisioned. I purchased the stone online from Florida and was very pleased with the care they took in securing the package. The stone is now set and I am so thrilled to be able to wear it every day!
Alice & the staff are wonderful . Great customer service , beautiful jewelry & gem stones. I live in Arizona and the item I purchased from them. I received 2 days later. Which was awesome! Very pleased with my purchase!
