Discover an exceptional 1.35-carat natural cobalt blue spinel from Ceylon, displaying a saturated ocean-blue color with bright electric-blue reflections. Its elegant oval cut, eye-clean appearance and untreated condition make it a distinctive loose gemstone for bespoke jewelry, fine jewelry and serious gemstone collections.
Natural Cobalt Blue Spinel from Ceylon
This earth-sourced gemstone was mined in Ceylon, Sri Lanka, and carefully cut and polished into a classic oval shape. Its vivid blue appearance can shift between deep cobalt blue and brighter cyan-blue flashes as the gemstone moves through different lighting conditions.
The cobalt characteristic has been confirmed. Supporting documentation should always be reviewed using the laboratory’s exact terminology. This natural spinel has received no treatment, allowing its color and internal character to remain as formed within the earth.
Gemstone Details
- Gemstone: Natural cobalt blue spinel
- Weight: 1.35 carats
- Origin: Ceylon, Sri Lanka
- Dimensions: 7.80 × 6.44 × 4.27 mm
- Shape and cut: Oval faceted cut
- Color: Saturated cobalt blue

What Can You Create With This Cobalt Blue Spinel?
The 7.80 × 6.44 mm oval proportions make this gemstone an attractive center stone for a bespoke engagement ring, promise ring, anniversary ring or contemporary cocktail ring. A classic four-prong setting would keep the blue color visible, while a protective bezel could create a clean modern profile.
For additional contrast, consider surrounding the spinel with natural diamonds or pairing it with tapered baguette side stones. White gold or platinum will complement its cool electric-blue reflections, while yellow or rose gold will provide a warmer, more dramatic contrast.
The gemstone could also become an elegant oval pendant, an heirloom necklace or a collector-focused fine-jewelry piece. Jewelry makers and designers are welcome to contact us for additional measurements, daylight videos and setting guidance.
A Rare Colored Gemstone for Collectors and Jewelry Lovers
Natural blue spinel is valued for its distinctive color, brilliance and individuality. Cobalt-associated blue material occupies a special position among rare gemstones, particularly when its color cause is supported by suitable gemological testing.
This loose gemstone is suited to collectors and clients who appreciate untreated spinel, Ceylon gemstones, faceted gemstones, precious stones and one-of-a-kind colored gemstones for bespoke jewelry designs.
Authenticity and Laboratory Testing
The gemstone includes Sapphire Pal authenticity confirmation. A GSL Australia laboratory test report can also be arranged upon request. Please contact us before purchasing if you require specific cobalt wording, origin documentation or additional laboratory services.

Before making a purchase, I inquired if they would also create a setting for whichever gemstone I chose. After they confirmed they would, I found the most beautiful purple/lavender sapphire. I purchase the stone and then sent them the vision I have for the setting. They delivered 100% of what I asked for and even more I could’ve dreamed of. The east to west half bezel sapphire ring is truly breathtaking. Communication was easy, fast and they were super honest about delays and whatnot. Even when I changed my mind on a few details in the beginning, they were so kind and had no problem adjusting what I asked for or confirming any questions I had. I’m so thankful to have worked with Sapphire Pal. Truly, thank you for bringing my sapphire ring dream to life! <3
Smaller than anticipated but absolutely beautiful 😄 Shipping was quick, and it was handled with care.
鑑別書もあって安心感があって良かった。
I had a very positive experience purchasing from SapphirePal. Pete was responsive, patient and professional throughout the process, and took the time to answer my questions in detail. He also provided additional photos and videos when requested, which was very helpful when buying a gemstone online.
The stone arrived safely, well packaged and as described, with the certification included. Overall, a smooth and reassuring experience, and I would happily recommend SapphirePal!
Absolutely stunning purchase once again from Sapphirepal 🤩 thsnk you !!
Very happy with colour and cut. A really pretty stone that I look forward to seeing as jewellery.
OMG, just spectacular, and excellent quality. Thanks again for your wonderful service and super quick postage time. I can't wait until I find my next precious gem.
Just stunning. I love this bi- Color sapphire. Flawless to look at, and expertly packaged and presented for my collection. Communication and postage time were exceptional. Thank you. I can’t wait until I have saved enough for my next special gem.
This gemstone is just perfect. My only criticism is the photos on your site were not the best quality for me. However, reading the description of this gem, together with photos, I took the plunge and ordered this true gem. I was so very pleasantly surprised when it arrived, as it certainly held up to its reputation. This is the first time I have purchased from sapphire pal. And I don’t think it will be my last either. Communication, fast delivery, and accurate descriptions, all to be commended. Thank you.
Very good quality sapphires and fast shipping! Thank you!
Hello! 🇺🇦I just wanted to thank you — my grey spinel from Australia has finally arrived in Ukraine. The stone is absolutely beautiful and exactly what I hoped for! Thank you for the great service, smooth delivery, and amazing customer support. Your support was invaluable at every stage of the long delivery journey. I’m really happy with my purchase and will definitely be ordering only from you from now on!
I received what i expected. The stones are with the certificates of authenticity. Had a little bit delay with the delivery due to post issues, I will buy the stones which are much bigger. It was a first try to buy on line. Highly recommend gem stones in this shop.
Absolutely wonderful stone. Great and fast customer service. My stone is actually 1.13ct so it was a tiny bit larger than listed, the colours are true to the photos (stunning!), had a jeweller look at it who said it was a "very nice QLD sapphire". Very very happy customer.
Exceptional service helping me find the perfect stones for my ring. The first set arrived and were not quite the right colour and Pete was more than happy to express post another set, which turned out to be perfect. Beautiful sapphires, fantastic customer service
⭐⭐⭐⭐⭐ Stunning Tanzanite – Exceptional Quality & Color!
I recently purchased this natural 1.36ct oval-cut Tanzanite from Sapphire Pal and couldn't be more impressed! The blue-purple hue is absolutely captivating — exactly what you'd expect from a premium earth-mined Tanzanite. The cut is clean and symmetrical, maximizing the stone’s brilliance and color play in natural light.
What really stood out was that this gemstone is 100% natural and untreated, which is increasingly rare for Tanzanites today. It’s perfect for a custom fine jewelry project, especially for a Tanzanite engagement ring or a one-of-a-kind pendant.
The shipping was fast, and the packaging was secure and elegant. I also appreciated the detailed product description and high-resolution photos — they matched the stone perfectly.
If you're looking for a genuine, ethically sourced Tanzanite with beautiful color saturation, this is the one. Highly recommend Sapphire Pal for anyone seeking collector-grade gemstones from Sri Lanka, Madagascar, or Africa.
