About the Item
Elegant. Versatile. Authentically Rare.
At SONYA K., we believe in creating pieces that invite personal expression. Our stackable rings are designed to be layered, mixed, and transformed—offering effortless elegance with endless styling potential.
This ring features a vivid 2.504 ct untreated purple sapphire from Madagascar—extraordinary for both its rich hue and rarity. Set in an 18K white gold band, it is 2/3 pavé-set with ~0.32 ct of F-color, VS-clarity round brilliant-cut diamonds (based on size 6.5). The band measures 1.6 mm in width, offering a refined silhouette for stacking or wearing on its own.
Why untreated sapphires matter:
While most sapphires on the market are heat-treated to enhance color and clarity, this one remains in its purest form—untouched by heat or chemicals. Less than 1% of gem-quality sapphires are truly untreated, making them exceptionally rare and highly collectible. Unlike treated stones, untreated sapphires retain their full intrinsic value and are cherished by connoisseurs for their authenticity.
ABOUT SONYA K.
SONYA K. was born from a moment of clarity in a world turned upside down. What began as a childhood love for gems evolved into a calling during the uncertainty of the COVID-19 pandemic and the heartbreak of war in Ukraine. Founded in 2022 by Sonya Konstantinovsky, the brand stands for timeless design, effortless elegance, and versatility.
At the heart of each piece is a meticulously chosen gem—tsavorite, spinel, tourmaline, unheated sapphire—selected not only for its beauty, but for its emotional resonance. Paired with bold geometric diamonds and set in clean-lined silhouettes, each design balances masculine structure with feminine fluidity and ease.
The SONYA K. design philosophy is rooted in the belief that a gemstone’s beauty should be enhanced, never overwhelmed. Minimal, refined silhouettes allow each stone to speak for itself.
“I’ve always admired the glamour of Hollywood’s Golden Age, but much of its jewelry feels too extravagant for modern life. Colored gems were often lost among the sea of diamonds, their natural beauty overshadowed. I wanted to create pieces where the gem takes center stage—bringing Old World glamour into a modern context, while staying relevant for the generations to come.”
At SONYA K., we see gemstones and people as remarkably alike—both take time to form, and both carry marks of the paths they’ve taken. We believe your jewelry should reflect your story: unique, evolving, and full of depth. That’s why we work only with rare, exceptional gems, crafting each piece to be lived in, layered with memory, and passed on with love.
Like a lifelong companion, our jewels are here to witness your journey—and one day, to accompany the next generation on theirs, carrying a piece of yours with them.

SONYA K.
Sonya Konstantinovsky's passion for color gems was ignited at a young age, traipsing through the city gardens of Odessa, Ukraine with her mother and grandmother. She fondly remembers her first gemstone purchase, a heart-shaped moonstone pendant, which sparked a lifelong obsession. After years of pursuing a safer career path, Konstantinovsky's love for gems was rekindled upon discovering tsavorite garnet. This transformative moment inspired her to research and collect rare, high-quality gemstones. As she honed her knowledge, she began designing jewelry that showcased her beloved gems. With the pandemic and war in Ukraine as clarifying reminders of life's brevity, Konstantinovsky finally introduced her fine jewelry line, Sonya K. Her designs emphasize clean lines, impactful color, and timelessness, with a focus on rare gemstones and bold diamonds. Konstantinovsky's enthusiasm for beauty is contagious, and her jewelry is crafted to be wearable, fun, and exciting. Many of her pieces are one-of-a-kind, making them as unique as the woman who wears them.
