STARLANKA buys rough at source and cuts it in-house in Bangkok, so a stone reaches you without the layers of margin a blue tourmaline normally collects between the mine and a retail counter. The price shown is the price — no negotiated tiers.

Retail price is our estimate of what a comparable stone typically costs at traditional retail. It is a comparison figure — not a former price at which this stone was offered.

“Faultless 😊. I am a Gemologist and bespoke Diamond jewellery Designer based in Scotland. Working on an unusual commission I required a large flawless rich green Tourmaline. Fortunately Starlanka had such a gemstone. My client had to approve of this purchase and to achieve this approval fine resolution videos were provided. From my initial enquires through the very helpful nature of Starlanka I made this purchase On receipt of this gemstone the gemologist in me tested the Gem to confirm it’s authenticity. Delighted with my purchase and I can now progress with this commission unhindered. Starlanka have a phenomenal collection of Gemstones available and I have no hesitation in thoroughly recommending this Company to anyone trade or otherwise who requires fine natural Gemstones I will most certainly be working with Starlanka as one of my network of Suppliers Regards to all potential purchasers Roy W Macdonald FGA DGA”
