About Our Gemstones

Hand Selected - Curated Collection by a Gemmologist
gemstones.jpg

The current coloured gemstones which are displayed in the Shop Gemstone section have been curated over the past few years from various trusted sources - primary and secondary. Our gem sources include parties such as directly from the miners who have cut material themselves, gem cutters who deal directly with artisanal miners and gem manufacturers who source quality material and have the gem material faceted/cut at their facilities using proper precision machinery.

Packaging of our Gemstones when shipping to you!

Each order is very special to me and I am thankful for it from the bottom of my heart as you support my dream of being active in the jewellery trade and letting me help you source gemstones to be in your future projects or perhaps to be an addition to your gemstone collection!

​

I want all gemstones to arrive safely with their future owner (you) and for that - correct packaging procedure goes into sending your parcel safely to you.

​

Each gemstone purchased comes in it's own gemstone box case, which is cushioned and gives maximum protection for the stone when being stored. The gemstone box is bubble wrapped and placed in a parcel box - that way both of us have peace of mind that your gemstone will arrive to you safely.
