Tianyu's history

We started business in 2001 making cubic zirconia(CZ) and jewelry with around 2000 employees. Shortly after, we manufactured spinel & synthetic emeralds, and corundum, with automatic machines. Once the Charles & Colvard moissanite patent expired, we started making moissanites. In 2014, we began to look into how to manufacture moissanites, and we began mass-producing them in 2016. In addition to the colorless, near colorless and warmer colors, we also supply light green, yellow, blue, dark greenish-blue, vivid yellow, champagne and black. Vivid yellow is the most popular of our colored moissanites. The yellow moissanite is much more challenging to produce. The color can be unstable, and the rough is in minimal supply. None of our colored moissanite is coated and is its natural color all the way through.

We were the first to produce this old european cut moissanite in China since 2017. We are also the first supplier to make the crushed ice cut moissanite since 2018. Furthermore, we have also produced other diamond cuts into moissanites like the Jubilee cut, Octavia cut, Lucere cut, criss cut, portrait cut, Taille Impératrice cut, Dutch marquise cut, Lotus cut, sheild cut, kite cut, lozenge cut, old mine cut and other antique cuts. Our moissanite cutters have 15 years of experience, so if you provide very clear images or video of a cutting that shows the face and the bottom of the faceting, we can develop this cut in 10 days. We can achieve this with 90% accuracy.

With the rise of lab grown gemstones, we have invested a lot of energy and money into producing lab grown gemstones since 2018 and now stock lab grown diamonds of all qualities and sizes, including pink lab grown diamond, blue lab grown diamond, yellow lab grown diamond, red lab-grown diamonds, and we can also customize old European cut and other antique cuts. All lab-grown diamonds with IGI certificates.

It is very easy to control the costs since we have our factory, and we can offer excellent customer service and products to our customers. We strive to achieve customer satisfaction…
