About Us

With over seven years in luxury retail, Rhianna has built her career at the intersection of fine jewellery, education, and global trade.

She is formally educated by the Gemological Institute of America (GIA) in Diamonds and Gemstones, giving her a deep technical understanding of what truly defines quality and value. Beyond the showroom, Rhianna has gained international experience attending major trade shows and wholesaling diamonds, working directly with global suppliers and international businesses.

This behind-the-scenes perspective allows her to demystify the diamond-buying process for her clients. As a diamond consultant, Rhianna supports individuals who want to invest in jewellery but don’t know where to start — offering clear guidance, honest education, and access to industry-level knowledge typically unavailable to the end consumer.

Her approach is discreet, educational, and client-led, ensuring every purchase is informed, personal, and meaningful.

What is the GIA?

Gemmological Institute of America

The Gemological Institute of America (GIA) is the global authority that sets the international standards for diamond and gemstone grading. They are the world’s most trusted authority on diamonds, gemstones, and pearls. They don’t sell jewelry — their entire job is to study, grade, and set the rules for how gems are evaluated.

Professional Expertise

I have completed GIA eLearning studies in Diamond Essentials, Diamond & Diamond Grading, Coloured Stones Essentials, Coloured Gemstones, Pearls and Jewellery Essentials giving me a strong foundation in professional gemstone evaluation and quality assessment. This training enables me to accurately assess diamonds and gemstones, understand the factors that influence their beauty and value, and clearly explain those qualities to clients.

From diamond grading and certification interpretation to identifying coloured stones, treatments, and pearl types, my knowledge ensures clients receive transparent guidance, informed recommendations, and confidence in every purchase.
