About Us

There is something mesmerizing about taking a rock that was formed millions of years ago and bringing out its natural beauty in a faceted gemstone. In order to share that beauty with those of you who also find gemstones intriguing, in 2017 we launched Rock Science Art (RSA Gems).

My name is Loren Brown and I am the founder of RSA Gems. After a 30-year career as an aerospace engineer and a mechanical engineer, I have decided to re-invent myself with a longtime favorite hobby and began this company. My wife, Nataliya, accountant by profession, left the work force several years ago to spend more time with our children, and now she has joined me in this new endeavor as a marketing manager and photographer. RSA Gems is a family-owned business. We live in Houston, TX with our two beautiful daughters, who also find gems a fascinating gift from nature. Maybe one day they will follow our passion and make it theirs, who knows.

At RSA Gems, we believe in natural gemstones. We do not provide stones that have been irradiated, filled, diffusion-dyed, composites, etc. The only treatment we may occasionally use is heat, and this is always disclosed in the description. Our gems are artisanal, not commercial in nature, but are still priced competitively. Nearly all gemstones in our collection are one-of-a-kind and precision-cut by myself in Houston. We scour the world for the best quality rough (superior color and clarity) and only our best stones appear here on this site. Some gems may also come from other reliable places, which are clearly identified as to the cutter and origin.

Our company is dedicated to cultivating a more transparent, sustainable, organic and compassionate gemstone field. From purchasing our gemstone rough from trusted sources to delivering outstanding authentic finished gemstones to our customers, our process is honest and sincere.

We are proud to be recognized internationally. Our gems found a good home in USA, Hawaii, Canada, Australia, New Zealand, UK, France, Netherlands, Switzerland, Czech Republic, Spain, Slovenia, Israel, Malaysia, Japan, Singapore, Hong Kong and Taiwan.

Thank you for visiting our page. We are really looking forward to getting to know you and creating a stellar piece of art for you or your special someone.
