An Untreated Green Sapphire with a Meaningful Heart Shape
The heart cut gives this natural Madagascan sapphire an expressive and symbolic appearance. It can represent love, commitment, friendship, remembrance, or an important personal milestone.
Its green color may appear deeper, lighter, warmer, cooler, slightly olive, or more blue-green depending on the light source, viewing angle, surrounding colors, camera settings, and screen display.
The gemstone has SI clarity, meaning natural inclusions and internal characteristics may be visible. These features should be reviewed as part of the stone’s complete appearance and individual identity.
Natural Madagascar Sapphire with No Treatment
This sapphire is disclosed as untreated. Its color and internal features have not been intentionally altered through a disclosed heating or enhancement process.
Untreated sapphire gemstones are often selected by gem collectors, jewelry makers, and jewelry lovers who value the characteristics created through natural geological processes.
Every earth-sourced gemstone has its own combination of color, inclusions, proportions, faceting, and response to light. These natural differences ensure that no two loose gemstones are exactly alike.
What Could You Create with This Green Heart Sapphire?
The heart-shaped outline and natural green color make this sapphire suitable for several meaningful jewelry designs:
- A natural green sapphire promise ring
- A romantic anniversary or milestone ring
- A heart-shaped sapphire engagement ring
- A delicate solitaire ring
- A halo ring with natural diamond accents
- A three-stone symbolic jewelry design
- A natural green sapphire pendant
- A personalized birthday or anniversary gift
- A bespoke heirloom jewelry piece
- An addition to a natural gemstone collection
Yellow gold could enhance the warmer green and olive undertones. White gold or platinum may create a clean, contemporary contrast, while rose gold could give the finished piece a softer and more romantic appearance.
Natural diamonds could add brightness around the sapphire without overwhelming its heart-shaped outline. A fine claw setting may keep the shape clearly visible, while a bezel or partial-bezel design could offer additional protection.
Heart-cut gemstones require a setting designed around their exact outline, including the cleft and pointed tip. Provide the full dimensions to your jeweler before purchasing a ready-made semi-mount. A custom-made setting will generally offer the safest and most accurate fit.
A Distinctive Loose Sapphire for Bespoke Jewelry
This untreated green sapphire offers a more individual alternative to traditional blue sapphire stones or colorless center gemstones.
Clients who admire Australian sapphires, Ceylon sapphires, Madagascan sapphires, Queensland sapphires, Tasmanian sapphires, peacock sapphires, blue-green sapphires, green sapphires, and other rare colored gemstones may appreciate its natural color and symbolic shape.
As a loose sapphire, it allows a jewelry maker to create a design around the stone’s exact dimensions, color, proportions, and natural characteristics.
Choosing a Natural Green Sapphire with Confidence
When selecting a natural sapphire, consider its complete combination of color, cut, clarity, dimensions, treatment disclosure, natural inclusions, and intended jewelry design.
Carat weight alone does not determine visible size. Review the face-up dimensions, side profile, heart symmetry, cleft, point, and available video before deciding whether the gemstone suits your preferred setting.

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.
⭐⭐⭐⭐⭐ Stunning Natural Blue Green Sapphire!
I recently purchased this Natural Blue Green Sapphire (0.43 Carat, Round Cut) and I couldn’t be more impressed! The stone has a truly captivating teal hue — a perfect balance between blue and green sapphire tones that shift subtly in different lighting. It’s even more beautiful in person than the photos!
The cut is precise and sparkles brilliantly despite its petite size, and the dimensions make it ideal for a minimalist ring or unique cluster setting. I appreciate that it’s a genuine earth-mined sapphire with no treatments — you can really see the quality and authenticity.
Shipping was fast, and the gem came securely packaged with a helpful authenticity confirmation. This is my second time ordering from Sapphire Pal, and their consistency and customer service are excellent. If you're looking for a natural unheated blue green sapphire for custom jewelry, I highly recommend this one!
