Terms & Conditions
These Terms form a binding contract between you and Lucerna Miami. Placing a bid, sending a customization inquiry, or buying anything from us means you have read them and agree to them. Section 17 contains a binding arbitration agreement and a class action waiver that affect your legal rights.

English is the governing language of these terms. The Spanish version is provided as a courtesy; if the two ever conflict, the English text controls.
1. Who we are
Lucerna Miami ("we", "us") is a diamond business based in Miami, Florida. We sell loose laboratory-grown diamonds and made-to-order mountings, principally through live broadcasts and by direct commission. You can write to us at any time at info@lucernamiami.com.
2. What we sell, said plainly
Every diamond we sell is LABORATORY-GROWN. We do not sell mined diamonds and we never present a grown stone as mined. Each stone is accompanied by a report from the International Gemological Institute (IGI). Laboratory-grown diamonds are chemically, physically and optically identical to mined diamonds, as both the U.S. Federal Trade Commission and the gemological industry recognize.
3. Lab-grown diamonds are not an investment
We say this before you spend anything. Laboratory-grown diamonds have modest resale value, and prices in the category have fallen steadily for years. We do not sell them as assets, we make no promise about future value, and any claim to the contrary — from whatever source — is not ours. Buy a stone because you like how it looks.
4. Prices and currency
All prices are in US dollars. Stone prices and mounting prices are quoted separately: a mounting price never includes the diamond unless we say so expressly in writing. The mounting prices shown by the configurator on this site are real prices taken from our chart, but they may change without notice, and a price displayed in error does not bind us. If a price is clearly wrong we will tell you, and you may cancel at no cost.
5. Live auctions
Bids placed during a live broadcast are binding offers to buy. We reserve the right to refuse or cancel any bid, to withdraw a stone before sale, and to close or reopen the countdown at our reasonable discretion. If a winning bid is not paid within the window announced during the broadcast, we may cancel the sale and re-offer the stone. Sales made through a third-party marketplace such as TikTok Shop are also subject to that marketplace's terms, which may give you additional rights.
6. What we are describing to you
The definitive description of any stone is its IGI report — not our spoken description, not the photograph, and not the color you see on your screen. On-screen color varies considerably by device, by brightness, and by the light in your room. We show each stone under magnification and under balanced light precisely to make that gap as small as possible, but we cannot warrant the calibration of your display.
7. Payment
We accept the payment methods shown at checkout. Title to a stone or a piece does not pass to you until we have received payment in full and it has cleared. Made-to-order work requires payment in full up front, because it is built for one person and cannot be resold.
8. Made-to-order work
A made-to-order mounting begins when you approve a drawing or a CAD model in writing. After that approval the order cannot be cancelled or returned except for a manufacturing defect, because the piece has been built for you. Timelines we give are good-faith estimates, not contractual obligations. If a timeline slips significantly we will tell you, and you may cancel an order that has not yet reached the bench.
9. Setting a stone you already own
We will gladly set a diamond you already own. If we do: you confirm that you are its lawful owner; we examine the stone before accepting it and will tell you if we see a risk; and, absent negligence on our part, the risk of breakage during setting is yours. Stones with inclusions reaching the girdle, large feathers, and emeralds carry a real risk when set, and we will say so before we start.
10. Shipping
Shipping is governed by our Shipping & Returns policy, which forms part of these Terms.
11. Returns
Returns are governed by our Shipping & Returns policy, which forms part of these Terms.
12. Limited warranty
We warrant that each stone matches the IGI report that accompanies it, and that each mounting is free from manufacturing defects for twelve months from delivery. This warranty does not cover ordinary wear, loss of a stone through impact, damage caused by alteration by another jeweler, or gold deformed by use it was not built for. This is the only warranty we give. To the extent permitted by law, all other warranties, express or implied, including merchantability and fitness for a particular purpose, are disclaimed.
13. Limitation of liability
To the maximum extent permitted by law, our total liability to you on any claim relating to a purchase will not exceed the amount you paid us for the item in question. We are not liable for indirect, incidental, special or consequential damages, or for lost profits. Nothing in these Terms limits liability that cannot lawfully be limited, including for fraud or willful misconduct.
14. Intellectual property
The Lucerna Miami name, the logo, the photography, the text and the design of this site belong to us. You may share our posts and our broadcasts as those platforms allow. You may not use our name or our images to sell your own products, or to imply that a third-party business is affiliated with us.
15. Acceptable use
Do not interfere with the site, do not attempt to access other people's accounts, do not scrape it, and do not place bids you do not intend to pay. We may suspend access to our broadcasts or our services for any of these.
16. Governing law
These Terms are governed by the laws of the State of Florida, without regard to its conflict of laws rules.
17. Arbitration and class action waiver
READ THIS CAREFULLY: IT AFFECTS YOUR RIGHTS. You and Lucerna Miami agree to resolve any dispute by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, in Miami-Dade County, Florida, or by videoconference. You and Lucerna Miami each waive a jury trial and waive participation in a class action. Either party may still bring a claim in small claims court. You may opt out of this arbitration agreement by writing to info@lucernamiami.com within 30 days of your first purchase; opting out does not affect your relationship with us in any other way.
18. Changes to these Terms
We may update these Terms. The version governing your purchase is the one posted on the day you bought. Material changes will be announced on this page with a new date.
