We began our trade many years ago, mainly with Topaz ( mass-produced semi precious gemstone), and even now, our heart lies with this beautiful gem. You may check out some of our exquisite Topaz gemstones here. With the success of our topaz products, we had ventured out and extended our list of semi precious gemstones. We currently supply with rubies, sapphires, emeralds, Montana sapphire, and those who are looking for teal sapphire rings for their weddings and engagement. You may also browse through our website for some interesting and informative gemstone news articles on loose gemstones.

However, we often undertake tourists in local Bangkok to support them with their purchases of precious gemstones from the hub of gemstones. We can guarantee good and reliable quality, reasonable prices, satisfactory pre-sale and after-sales services, prompt replies and express and safe delivery.

We source our raw materials in the form of wholesale gemstone crystals, from all over the world. Brazil, Africa, Srilanka (Ceylon), Burma, India, Madagascar, China, Russia and some other countries. Once obtained, these raw materials are transported to our gemstone factory in bulk (most semi precious stones for India, precious stones for Thailand), where our expert craftsmen cut, shape, polish and produce the final loose gemstones.

Having our own manufacturing unit benefits us immensely in supplying gems at competitive prices with controlled quality to our clients.

Another concern you may have is the sourcing of these gems, as many illegal mining operations are on the rise. We at, Navneet Gems and Minerals, have started a brilliant initiative to procure mostly ethically sourced gemstones. We largely source the rough cutting materials from mostly Thailand, Srilanka, India, Australia as many African nations have been involved in unfair trade. However, some percentage of our precious gemstones like Tourmalines, Tsavorites, Rubies (Mozambique), Sapphire (Nigeria, Kenya, Madagascar) come from African countries. We also put in efforts to be in touch with the miners over there to ensure they are mining in good conditions that ensure the happiness of the miners, provide basic pay and healthy mining conditions, following all laws. Although this increases the setup costs, we consider this is a start that we wish to keep implemented throughout. We cut and polish all gemstones in our own gemstone cutting factory and also take cutting projects to move towards a responsible safe cutting and polishing.

In case you would like to discuss anything about Loose Wholesale Gemstones and their sourcing, do not hesitate to send an email directly to Navneet at navneet@navneetgems.com. Also, Check out our active social media: Instagram.

Nevneet was an absolute gem to work with - top quality customer service - sent us more videos & photos asap, shipped our order crazy fast, and was all around delightful to work with. The s&p diamonds we got from him were lovely - no weird surface blemishes - nicely cut, fun shapes, fun, vibrant, lively stones that are perfect for the collection we're currently working on. Look forward to doing business again! 💜

I couldn’t be happier with my Amethyst, Citrine and Topaz! Cut brought out the best color and brilliance. Looking forward to years and years of business, they have earned my business!

I purchased several unique cut salt and pepper diamonds and teal sapphires which I've been looking for. Those stones are absolutely beautiful and look exactly same as the picture Navneet Gems sent me. Color, Shape and Quality are all what I expected. Due to the current situation we can't travel so east, it was challenging for me to purchase gems via virtual communication. However, Navneet Gems & Minerals meet my expectation. They are reliable, very responsive and also arrange the delivery very fast. Thank you so much.

I ordered 20 cts of Australian peacock and parti-sapphires from Navneet. Every stone is beautiful, well-cut, and exceeded my expectations. I’ve received numerous requests for Australian stones and I was looking for a new supplier. I messaged Navneet requesting stones and he immediately responded. He hand selected a parcel of stones in the size and color ranges I was looking for. The stones were shipped quickly and arrived well-packaged. I will absolutely order more stones from him. Honestly, I don’t write many reviews but was impressed with the stones and customer service I received.
