QSUR
Jewelry Co-creation

A lab-grown diamond we grow, and a jewel defined together with you

All QSU products use lab-grown diamonds. Lab-grown diamonds have the same chemical composition and crystal structure as natural diamonds, but a different origin; they are two distinct product categories.

The square is the most restrained geometry. A princess center stone sits steadily in four prongs, without additional accent stones; the yellow is already enough to be seen. Made for the everyday between commuting and formal occasions.

Three small center stones in pink, yellow, and blue sit along a fine chain, like a morning that was remembered. Each stone stands on its own, without ranking center stone against side stones. The light in wear is small and restrained.

04 · LAB-GROWN DIAMOND

About lab-grown diamonds

What it is

A lab-grown diamond is a diamond grown under laboratory conditions. Its chemistry is carbon, and its crystal structure is the same as a natural diamond. It is not a simulant: cubic zirconia, moissanite, and similar materials differ in both composition and structure.

The difference is how they form
One is formed by geological processes deep in the earth; the other is grown in equipment through a controlled technical process.

Where QSU's lab-grown diamonds come from

Grown in-house by Qiansheng Superhard Materials, not sourced from outside. Cutting and polishing are completed by professional partners. Center-stone specifications and grading reports are confirmed on the actual order.

IGI report / NGTC report
The report states material, weight, cut, color, and clarity grades. When ordering, you may choose whether to issue a report and which type.
05 · YOUR STORY

You do not need to know what it should look like first.

A co-created jewel can begin with a mood, or with a sketch drawn by hand. Tell us what it should express, and we look for a design language in your story, images, and outline.

You can tell us like this
“Like the first snow of winter.” “Want to keep the waves from its first trip.” “Only know it should be a very restrained, quiet outline.”
