Lovely red Umba sapphire.
Umba sapphires are unlike any other sapphires in the world. Mined from the Umba River Valley of Tanzania, these rare gemstones are celebrated for their extraordinary natural color range—soft greens, stormy blues, golden ambers, earthy teals, smoky violets, and shifting tones that often appear together within a single stone.
These sapphires have been gently tumbled rather than traditionally faceted, allowing their natural beauty and color to emerge in an organic, elemental form. The tumbling process softens the surface while preserving the character of each gem, creating stones that glow with depth, texture, and a quiet brilliance impossible to replicate with calibrated cuts.
No two Umba sapphires are ever alike. Their inclusions, color zoning, and raw individuality are part of what make them so sought after by collectors and artists alike. Each stone feels ancient, shaped by the earth over millions of years and finished only enough to reveal the beauty already within.
Perfect for one-of-a-kind jewelry, these sapphires pair beautifully with organic gold work, rough diamonds, and heirloom-inspired designs. Their uncommon colors and natural forms make them ideal for those seeking something authentic, rare, and deeply connected to the natural world.
I hand carved this setting in wax and cast it in recycled solid 14k yellow gold using the lost wax casting process. This one-of-a-kind raw gemstone ring is a size 7 it can be resized up or down for you as needed. The sapphire stone measures about 7x5mm. The side diamonds are around 3mm
Throughout all time and history in every tribe and culture all around the world crystals, minerals and gemstones have been used for healing, luck, divination, adornment vibrational medicine and so much more. Sapphire is a stone for mental clarity and helps with making decisions. It is a stone of royalty meditation and creativity.
