Our Story

Every moment has a new facet.

Polygia is the jewelry brand of Yongzuan Jewelry, based in Guangzhou. We make pieces for the chapters you write yourself — big wins, small wins, new beginnings, and the quiet just-because days in between.

What we make

Our collections center on 925 sterling silver (often with rhodium plating where noted on the product), set with lab-grown diamonds and colored gems, and moissanite. Exact metal finish and stones are listed on each product page.

How we make it

Polygia pieces are made to order. Standard production is about 21 business days (rush about 14 when offered); silver and platinum pieces can take longer. Shipping is additional — typically 3–5 business days in the U.S. and 5–10 internationally. See Shipping & Delivery on each product page and our Shipping policy for details.

Chosen by you. For you.

We design for self-reward and meaningful gifting: jewelry that marks a moment you chose for yourself, or for someone you love.
