Experience the MiaDonna difference for yourself while shopping the best lab-grown diamonds in Portland, Oregon.
We're reinventing the fine jewelry shopping experience:
No crowds, personalized service, exceptional quality, ethical diamonds, affordable pricing, easy parking, and a glass of champagne!
The way it's supposed to be.
To ensure the highest quality, all of our jewelry is handcrafted and made to order to your specifications, aside from ready-to-ship items. Once your order is received and processed,
it will take 10-15 business days to craft the jewelry.
Once completed, your order ships domestically via UPS 2-Day Air or internationally in approximately 5 to 7 days, depending on the destination country.
Ready-to-Ship items are pre-crafted and will ship the same business day with free 2-day shipping (domestic) if ordered before 11:00 am PST,
Monday through Friday. Rings needing to be resized will require two days of additional processing time. Next-day shipping is available upon request for an additional charge.
Loose Stones ship in approximately 5 business days from order.
All purchases made in our Portland, Oregon store and most online purchases are not charged sales tax.
Should sales tax apply to your order, this will show up in your shopping cart when checking out. As of 2023, we only charge sales tax to online orders shipping to WA, CA, IL, and FL
