Delfi vs Lucian vs Cushion Studs vs Emerald Pendant vs Oval Eternity Band: Which One Should You Buy? [2026]

Loose Grown Diamond: 5 Pieces Compared
We compared five real Loose Grown Diamond listings — two build-your-own-ring settings, a stud earring pair, a solitaire pendant and a full eternity band — to help you pick the right piece and price.
Which Loose Grown Diamond piece should you buy?
It depends on what you need. Two of these five listings — the Delfi and Lucian rings — are settings only, priced without a center diamond, while the cushion studs, emerald pendant and oval eternity band already include all of their diamonds in the listed price. If you want the most "complete" purchase for your money, start with the eternity band; if you're building a custom engagement ring around a stone you've chosen separately, the ring settings are the better starting point.
Same manufacturer, five very different price points
All five pieces come from Loose Grown Diamond, a company that says it has manufactured diamonds since 1984 out of its own facility, and offers 100% GIA, IGI or GCAL-certified lab-grown diamonds. Prices below reflect what we found on each individual product listing at the time of research and can change.
Price, what's included, and who it's best for
| Delfi Engagement Ring (LGDBR-83) | $1,007 · setting only · 0.30ct DEF/VVS-VS pavé sides · 14K white gold · Best for: building a custom ring around your own certified center stone |
| Cushion Cut Stud Earrings (LGDSE-10) | $656 · complete pair · 0.30ctw included · 14K/18K/platinum · Best for: everyday cushion-diamond studs, diamonds included in price |
| Emerald Solitaire Pendant (LGDFSP-06) | $146 · complete pendant, chain sold separately · 0.25ct · 14K/18K/platinum · Best for: budget entry point or gifting |
| Oval Full Eternity Band (LGDWE-20) | $1,434 · complete band · 3.00ct / ~18 diamonds · 14K white gold · Best for: a fully-set statement or stacking wedding band |
| Lucian Hidden Halo Ring (LGDBR-30) | $1,102 · setting only · ~0.45ct hidden halo + pavé accents · 14K white gold · Best for: extra hidden sparkle on a BYO-center-stone ring |
A quick take on each piece
Best classic setting for a custom build
A timeless pavé tulip-head setting with side diamonds included — pair it with your own certified center stone.
Best complete, wear-today pair
0.30ctw of cushion diamonds already included, no separate center-stone shopping required.
Best budget entry point
The most affordable real lab diamond piece here, though you'll need to add a chain separately.
Best fully-set statement piece
3.00ct across ~18 diamonds, all included — the most "complete" purchase of the five.
Best for extra hidden sparkle
A hidden-halo setting for shoppers who want more brilliance without a visible halo ring — again, BYO center stone.
Pros & Cons
Pros
- All five pieces share the same 30-day return window and free, insured US shipping.
- All are eligible for GIA/IGI/GCAL certification on the relevant stones (default or on request).
- Manufacturer-direct pricing across the board, with each item discounted from a higher list price.
- A single 5.0/5 store-wide Trustpilot rating (3,000+ reviews) backs the retailer overall.
Cons
- Two of the five (Delfi, Lucian) are setting-only — easy to underestimate your real total cost if you forget the center stone.
- Default melee diamonds ship non-certified unless you request and pay for grading.
- All five require 3–4 weeks of made-to-order production before shipping.
- None of the five had SKU-specific review data; ratings here are store-wide, not per product.

Our pick: the Oval Eternity Band for value, the Lucian for sparkle
For most shoppers wanting one complete, fully-set purchase, the Oval Eternity Band offers the clearest value. If you're building a custom engagement ring and already plan to shop for a center stone separately, the Lucian Hidden Halo setting is the standout for extra brilliance, with the Delfi as the more classic alternative.
