While we primarily work with semi precious gemstones and crystals of more than a 100 different varieties, our company is also the supplier some of the most finely cut and hand picked precious gemstones from our factory.What separates us from the pack is that wholesale gemstones and crystals of such exceptional make known to be quite difficult to source because of their quality, varied colors and erratic prices. That’s where we, at Navneet Gems, hope to make a difference. As a wholesaler, we provide the finest loose gemstones consistently along with cutting services and faceting of rough stones/preforms. Buying gemstones wholesale in Thailand is guaranteed to be a livening experience with us.

Very much enjoyed visiting Navneet Gems when I was in Bangkok. I was given the time to look through the stones in a relaxed and friendly environment with no pressure to buy. Very pleased with our purchases and I am already thinking about the next order.

We have ordered a few thousand very small cabochons from this company now and are very pleased with the consistency.
Hopefully we will be continuing to work with you guys for a long time!

Navneet was very accommodating and friendly. He patiently answered all my questions and gave suggestions on which tourmaline I should pick out. It was difficult to buy on the spot but I impulsively did anyway! Very happy with my purchase!

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 only ethically sourced gemstones. We largely source the rough materials from mostly Brazil and India (our cutting location of gemstones) as many African nations have been involved in mining controversies. However, some percentage of our precious gemstones like Tourmalines, Tsavorites, Rubies (Mozambique), Sapphire (Nigeria) comes 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 set-up cost, we consider this is a start that we wish to keep implemented throughout. 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
