What Types of Diamonds Does Leigh Jay & Co. Use in Its Rings?
Updated
Leigh Jay & Co. states that its rings are made with three types of diamonds: vintage diamonds, conflict-free diamonds, and lab-grown diamonds. That means you are not limited to one sourcing option when you shop for an antique-style, vintage-inspired, or custom ring — the choice depends on the look you want, the stone's history, and how you weigh origin against budget.
The Three Diamond Types at a Glance
| Diamond type | What it means at Leigh Jay & Co. | Why you might choose it |
|---|---|---|
| Vintage diamonds | Diamonds reclaimed from older or antique jewelry and reused in new or restored pieces | You want a stone with age and character, and you prefer reusing existing stones over newly mined ones |
| Conflict-free diamonds | Newly sourced diamonds the shop identifies as conflict free | You want a newly cut stone but care about how it was sourced |
| Lab-grown diamonds | Diamonds created in a lab rather than mined | You want a diamond look, often with more size or clarity for the money, and no mining involved |
Vintage Diamonds
Vintage diamonds are the stones that give the shop its name. Rather than only selling intact antique rings, Leigh Jay & Co. describes making rings with vintage diamonds — meaning older stones are set into new or custom designs.
This matters for two reasons:
- Appearance. Older cuts were fashioned by hand before modern cutting standards, so they tend to have different proportions and light behavior than a modern brilliant cut. If you want that softer, older look, a vintage stone is the direct route.
- Reuse. Putting an existing diamond into a new setting keeps the stone in circulation instead of leaving it in a drawer.
If you are choosing between an intact antique ring and a new ring built around a vintage diamond, the trade-off is usually authenticity of the whole piece versus getting a design and fit made for you.
Conflict-Free Diamonds
The site lists conflict free diamonds alongside vintage and lab-grown stones. This is the option for a newly sourced, mined diamond where the stated concern is the stone's origin rather than its age.
A practical note: "conflict free" describes sourcing, not appearance. A conflict-free diamond can be any cut or quality, so you still need to compare the usual factors — cut, color, clarity, carat — within that category.
Lab-Grown Diamonds
Lab-grown diamonds are offered as a third option. They are chemically and optically diamonds, but they are produced in a lab rather than mined.
The usual reasons to consider them:
- Size and quality per dollar. Lab-grown stones generally let you go larger or cleaner within a given budget.
- No mining. If avoiding mined stones is the priority, this is the clearest choice.
- Resale. Lab-grown diamonds typically resell for much less than mined stones of similar specs, so buy them for the ring, not as a store of value.
How to Decide
Ask yourself which of these describes you:
- "I want a stone with history and an older cut." → Vintage diamonds.
- "I want a new, mined diamond and care about ethical sourcing." → Conflict-free diamonds.
- "I want maximum size or clarity for my budget, or no mining at all." → Lab-grown diamonds.

Because diamond type affects both the look of the finished ring and its cost, the most reliable way to compare vintage, conflict-free, and lab-grown stones is to see them side by side and ask which category a specific ring uses.
