All FAQs
Does your fine jewelry come with a certificate?

Our fine jewelry collection—including wedding rings, pendants, necklaces, bracelets, chains, and earrings—does not include an individual diamond grading certificate by default.

These pieces are crafted with high-quality DEF color and VVS/VS clarity lab-grown diamonds, offering excellent brilliance and value.

If you’d like your jewelry to be individually certified, we can arrange certification upon request. Please contact us before placing your order for available options and pricing.

What is the crafting time for rings and fine jewelry?

Our standard crafting time is up to 2 weeks for rings and fine jewelry before shipment.

If you select Express Shipping, your order may be prioritized, which can help reduce the overall delivery time.

Please note: Crafting times may vary depending on the design, customization, and order volume. If you have a specific delivery date in mind, please contact our support team, and we’ll do our best to accommodate your request.
