Natural Green Sapphire – 0.51 Carat Trillion Cut
Add an individual touch to your next jewelry design with this 0.51 carat natural green sapphire from Madagascar. Its trillion cut brings a triangular outline to the stone’s green color, offering a distinctive starting point for a custom ring or pendant.

A Green Trillion Sapphire for Custom Rings and Pendants
The triangular shape lends itself to geometric jewelry designs. Set it as the focal point of a delicate pendant, explore an asymmetric ring, or use it as an accent in a bespoke piece. Yellow gold offers a warm pairing with green, while white gold provides a cooler finish.
For a custom engagement ring or promise ring, ask your jeweler to assess the stone and recommend a setting that protects its pointed corners. Its unequal length and width make it especially important to check the actual outline before choosing a semi-mount setting.
Understanding Its Natural Characteristics
This sapphire is listed with no treatments, making it an option for buyers seeking an untreated green sapphire. Its SI clarity grade indicates slight inclusions; it should not automatically be assumed to be eye-clean. Their visibility depends on their position, the lighting, and the viewing distance.
If you would like to assess the color, cut, or inclusions more closely, please request additional photos or a video before purchasing. Your gemstone includes an authenticity confirmation. If an independent laboratory report is important to you, contact us to discuss availability and any additional cost.

Amazing quality product as promised! Delivered efficiently and safely as well 👍
very nice colour
Lovely stone and packaged very nicely.
Correct size and weigh.
Fast delivery
I LOVE my ring, thank you so much Sapphirepal
It fits perfectly and I love the setting too. The stones are stunning!!!
Thank you again for delivering quality and helpful support.
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!
