Loose Grown Diamond Delfi Engagement Ring Review
A 14K white gold, 6-prong tulip-head engagement ring setting with a full pavé diamond band from a manufacturer-direct lab-diamond seller — built to be paired with your own separately chosen center stone.
Is the Delfi setting worth buying?
Yes, if you understand what you're buying: a pavé engagement ring setting, not a complete ring. Loose Grown Diamond positions itself as a manufacturer that has produced diamonds since 1984, and the Delfi setting reflects that direct-to-consumer approach — a 6-prong tulip head on a full pavé band, discounted from $1,107 to $1,007, with 0.30ct of DEF color/VVS–VS clarity side diamonds included. Your center diamond is chosen and purchased separately from the site's loose-diamond catalog.
A manufacturer-direct pavé setting, not a finished ring
Loose Grown Diamond says it operates its own diamond manufacturing facility (the company states it has been in the industry since 1984) and sells both loose certified stones and finished settings like the Delfi. Because settings and center stones are priced and sold separately, this build-a-ring model can undercut boxed "one price" competitors — but it also means you need to budget for two purchases, not one.
What you're actually getting for $1,007
6-prong tulip head on a full pavé band
The 1.80mm band is finished in 14K white gold by default, with yellow gold, rose gold, platinum and two-tone combinations available at checkout.
0.30ct of DEF color, VVS–VS clarity pavé diamonds
The side stones lining the band are included in the setting price. Like most melee diamonds industry-wide, they ship non-certified by default.
Pick your own GIA, IGI or GCAL-certified center diamond
Loose Grown Diamond sells loose lab-grown diamonds separately, filterable by shape, carat and certifying lab, which you then have set into this Delfi mounting.

Pros & Cons
Pros
- Manufacturer-direct pricing, discounted from $1,107 to $1,007.
- Classic, versatile pavé tulip-head setting with 0.30ct of side diamonds included.
- Wide range of metal and two-tone customization options.
- 30-day return window with free, insured US return shipping.
- Backed by the retailer's price-match promise (the store's own claim).
Cons
- The $1,007 price is for the setting only — a certified center diamond is a separate purchase.
- 3–4 week made-to-order production means it's not a rush option.
- No SKU-specific customer rating was found; the score above reflects the store's overall 5.0/5 Trustpilot rating, not reviews of this exact setting.
- A $150 fee applies if you return the ring without its original grading documentation.
