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!
