Since 2016
Our Story
In 2016, our journey began with a simple goal: to make fine jewelry more accessible without compromising on quality or ethics.
Based in Bangkok, Thailand, we quickly noticed a gap in the market. Luxury jewelry came with inflated prices, while most affordable alternatives were made from low grade materials like cubic zirconia or glass filled stones that lost their shine within months. We believed there had to be a smarter way: jewelry that could combine true craftsmanship, modern materials and honest pricing.
The discovery
After months of research and visiting jewelers across Bangkok, we came across moissanite, a gemstone with remarkable brilliance, durability and value.
At first, we were skeptical. Could it truly match the beauty of a diamond? Our curiosity led us to the United States, where moissanite had already gained recognition among modern consumers who valued transparency and sustainability.
There, we learned that genuine moissanite scores 9.25 on the Mohs hardness scale, making it one of the hardest and most durable gemstones in the world. It shares many of the optical qualities of a diamond and even surpasses it in brilliance. This confirmed what we had been searching for: a sustainable, high performance alternative to mined diamonds that offered real value without compromise.
The beginning of RIVA Moissanite
That same year, we established RIVASOM Co., Ltd., the parent company of RIVA Moissanite, with a clear purpose: to provide access to ethical gemstones and fine jewelry that meet the highest standards of craftsmanship and integrity.
We built partnerships with reliable moissanite and lab grown diamond suppliers, ensuring authenticity, consistency and verified quality in every stone we source.
RIVASOM Co., Ltd. is founded in Bangkok and RIVA Moissanite begins.
We open our office on Sukhumvit Soi 40.
Engagement rings and custom jewelry in moissanite and lab grown diamond, shipped worldwide.
Our mission
