Is Crystal Opal Really Crystal?
No, Crystal Opals are not crystals.
Opals are amorphous silica rocks that lack formal crystalline structure. Crystal Opals have earned their (somewhat misleading) title due to their diaphanous appearance.
CRYSTAL OPALS:
- Are transparent or translucent.
- Can carry different base tones (ie: black, semi-black, white).
- Are famously mined in areas like White Cliffs and Lightning Ridge, Australia.
Q: Our favorite thing about Crystal Opals?
A: They reach their full color potential when they make contact with your skin. We see them as a symbiotic stone.
Real Reviews from Real Customers
Let customers speak for us
from 90 reviewsI was thoroughly impressed from the first interaction. Swift and sufficient communication, anticipation of needs and the ability and willingness to exceed expectations by miles-that’s what i noticed initially. Her service should be the benchmark by which all others are judged. The ring itself was exactly as pictured and upon initial inspection it was quite clear that it was well made with attention to detail and quality materials. I am so thankful there are people like her and i appreciate someone who clearly does what they do with genuine care and passion.

I LOVE buying jewelry from NIXIN! It’s ALWAYS such a treat! These earrings are small but they are stunning and so easy to wear. The emeralds sparkle like only Nicki and her team can make a gem shine. The opals are a perfect compliment to the rich green of the emeralds! From placing the order, to claiming my rewards, and receiving the carefully and beautifully wrapped package which proclaims, ‘I deserve this very special jewel’ the experience is consistently flawless! The experience makes me look forward to ‘next time’. 💖

WOW 🤩 If you want your jewelry to sparkle like new without having to worry about harming your gems, including your precious opals, you must try this cleaner! I have just finished going through ALL my jewelry, even those pieces I had given up on from decades past, and I cannot believe how fresh and new every single piece sparkles and shines! I’ve tried so many products sold to me by other jewelers only to be disappointed. Cleaning my opals always scared me to death! And silver jewelry, I would end up putting those pieces aside. I have a silver ‘Initial Necklace’ from Tiffany’s which turned dark grey. In a half an hour, it looked as shiny as when I bought it 10 years ago! It was amazing!!! If Nicki recommended it, I felt safe to use it on all my jewelry. I highly encourage collectors to buy this product. I now have refurbished my whole collection! It is the only jewelry cleaning product that I have ever used that I didn’t have to ‘work’ at getting an item super sparkly! Spray, brush lightly and rinse! Thanks Nicki!!

Exceptional from first glance!! A+++ communication, service and art.

So beautiful!! Lovely earrings. So happy with my purchase.

Gorgeous necklace! Top notch communication from seller and very fast shipping! Couldn’t be happier!

This cleaner works wonderful!

The Celestial ring is exactly what I was hoping for - understated elegance and beauty. Customer service was fabulous. Will be watching this shop for other items.

Not only are Nicki’s designs absolutely stunning— she’s absolutely wonderful to work with. Responsive, considerate, professional and fun— felt like I was working with a friend!
Whenever I’m having a crappy day, I peruse her designs for a quick smile. The pictures don’t do it justice, wait until you have one of these stunners in your hands!

Beautiful purchase - Niki was excellent with shipping details.

I LOVE it !!!!!!
Great transaction, great communication, perfect and beautiful in every way !!!
I will be back for more !!!

Wonderful merchandise! Took very personal good care of!

This amazing Cobbled Heart Opal Necklace takes your breath away! The Design and execution of all Nicki's pieces is faultless.
Looking on the website at her incredible work is one thing, but when you actually see these gorgeous pieces of art up close, they are even more beautiful than imagined. I have purchased 7 pieces so far, all will become family heirlooms!

I love shopping for Nixin products. I started with an engagement ring and have come back every year. Working with them is always an amazing customer service experience and I'm never disappointed with the quality and how much my wife loves the gifts!

ANSWERS TO FREQUENTLY ASKED QUESTIONS
Opal Necklace FAQs
Are the opals used in your pendants solid or doublets?
NIXIN currently uses solid Australian opals — not doublets or synthetics. Each opal is carefully chosen for its natural beauty and integrity, ensuring your necklace is a true, earthen treasure.
Can I wear my opal necklace every day?
Yes… but. Opals are softer stones, and while you can wear your necklace daily, we recommend removing it before strenuous activity, impact, or exposure to harsh conditions. A little care goes a long way. Learn more in our blog on Proper Opal Care Techniques and Guidelines.
How should I store my opal necklace?
Store your opal necklace in a soft, fabric-lined box or pouch, away from strong light, extreme temperatures, or other gemstones. Keeping it separate helps prevent scratches and preserves the luminous surface of the opal.
Do your necklaces come with chains?
Yes. Every NIXIN pendant arrives on a solid gold chain thoughtfully selected to best complement the individual opal and design. Chain length is noted in each product description.
What is a “picture stone” opal pendant?
A picture stone is an opal whose play-of-color creates a scene—waves, skies, or a dreamy horizon. These natural artworks are collector favorites and signature to the NIXIN aesthetic. Learn more in our blog post on opal picture stones.
Are your necklaces solid gold?
Yes. All NIXIN Jewelry necklaces are handcrafted in 14k or 18k solid gold. We do not use gold plating or fill, ensuring your piece offers both beauty and heirloom-level craftsmanship.
How can I prevent my chains from tangling?
Before storing your necklace, close the clasp. Then place the necklace in a small ziplock bag, with the clasp and about an inch of chain on each side sticking out. Seal the bag with the chain mostly inside. Store one necklace per bag to keep it tangle-free.
What makes NIXIN opal necklaces unique?
Each NIXIN opal is hand-selected for its idiosyncratic beauty—color, light, texture, and movement that feel otherworldly. No two are alike. It’s a wearable piece of art and a testament to nature’s imagination.

What's the Difference Between Opal Doublets, Opal Triplets, and Solid Opals?
