Conflict-Free Love Shining Brighter

Peaceful Origins · Sustainable Beauty · Unmatched Purity

At Ti&Dia Jewelry, we are passionately committed to crafting stunning diamond jewelry that embodies modern values - sustainability, ethical sourcing, and breathtaking beauty that inspires awe.

Our lab-grown diamonds

Our lab-grown diamonds possess the identical chemical composition and dazzling fire as natural diamonds, yet they eliminate the environmental devastation of mining and the violent conflicts tied to natural diamond trade. This makes them a greener, more ethical, and remarkably cost-effective choice. Sourced from China, our loose lab-grown diamonds are graded using the same rigorous 4C standards (carat, clarity, color, and cut) as natural diamonds. Meticulously selected, each stone boasts a clarity of VS1 or higher, a color grade of D or above, and an excellent (EX) or better cut - delivering exceptional quality, mesmerizing brilliance, and industry-leading affordability. We believe everyone deserves to celebrate life’s precious moments with joy and ease, free from financial burden.

We proudly offer high-grade lab-grown diamond loose stones and exquisitely handcrafted, lab-grown diamond-set jewelry. For any lab-grown diamond over 0.5ct set in our jewelry, we provide an IGI certificate. Every piece of our jewelry is made-to-order by skilled artisans, not mass-produced on assembly lines, ensuring unparalleled craftsmanship and quality.

For an even more budget-friendly option, we also provide loose moissanite and jewelry adorned with it. 

Moissanite - Born from the Stars, Perfected in the Lab

Discovered in a meteorite over a century ago, moissanite is literally “star-born.” Today, our lab-grown moissanite possesses even greater fire (2.5× more than diamond), exceptional brilliance and rainbow flashes that never fade. Every stone is hand-selected to D-color equivalent and VVS clarity. Heirloom-quality sparkle at a fraction of the price, and 100% conflict-free.

Lab-Grown Colored Gems – Real Sapphire, Ruby & Emerald, Just Better

Our lab-grown rubies, sapphires and emeralds have the exact same physical, chemical and optical properties as mined stones, only more perfect. Pigeon-blood ruby, royal blue sapphire, Colombian green emerald...Vivid saturated colors that never fade, and grown with zero environmental damage. Every colored gem is the same beauty as nature’s rarest treasures, responsibly created for the modern world.

At Ti&Dia, we believe luxury should never cost the earth, or your ethics.

Identical to mined stones in every way, except they’re more brilliant and genuinely sustainable. From loose stones you can hand-select to fully custom engagement rings and everyday fine jewelry, we’re here to help you mark life’s biggest and smallest moments with sparkle that lasts forever.
