Why Oval Sapphire Engagement Rings Keep Winning
If you've spent any time looking at engagement rings in the last two years, you've probably noticed: oval cuts are everywhere, and sapphires are no longer the "alternative" stone — they're the headliner. There are reasons that go beyond trend.
The oval cut works. An oval-cut stone elongates the finger, sits flatter against the hand than a round, and reads about 10% larger than a round of equivalent carat weight. It catches light from a wider range of angles. It works with vintage settings and contemporary settings equally well.
Sapphire is built for daily wear. At Mohs 9 hardness, sapphire is the second-hardest gemstone after diamond. That means it doesn't scratch in normal life. You can wear it through dishes, the gym, gardening, anything short of taking a hammer to it. Diamonds are slightly harder, but sapphire is the threshold above which a stone is genuinely durable for a lifetime.
Color gives you flexibility diamond can't. Beyond the iconic deep blue, sapphires come in green, teal, white, pink, yellow, and the rare padparadscha (peach-pink). You can pick a stone that says something about the person wearing it without having to reach for a different gem family entirely.
And practically: sapphires cost meaningfully less per carat than diamonds of equivalent visual quality. A 2-carat oval sapphire engagement ring runs roughly 30–60% less than a 2-carat oval diamond engagement ring with comparable craftsmanship.
The Three Picks

Each of these is one of a kind. Each is currently in our engagement rings collection. We've shown each ring two ways: a clean studio shot so you can see the metalwork and stone clearly, and an on-the-hand shot so you can see how it actually wears.
Pick №1 — The Vintage Statement
Vintage Oval Sapphire Engagement Ring
3.10tcw Natural Sapphire & Diamond, 14kt White Gold
The piece for someone who wants the ring to look like it has a history before they even put it on. Center stone: a natural oval-cut sapphire with documented provenance, set in a 14kt white gold vintage-style mounting with diamond accents. The 3.10 total carat weight makes this read as a statement ring without crossing into "costume" territory.
Best for someone drawn to vintage engagement rings, Edwardian or Art Deco aesthetics, or who already wears antique-feeling jewelry. The elongated oval flatters longer fingers especially.

3-Stone Oval Sapphire Diamond Ring
with Diamond Accent Side Stones, 1.95tcw
The classic three stone sapphire engagement ring setting — past, present, future — done with a deep blue oval sapphire flanked by two diamond accent stones plus pavé side details. Total carat weight is 1.95, which sits in the sweet spot for daily-wear engagement rings: substantial without being aggressive about it.
The three-stone setting does something the solitaire can't: the side stones make the center sapphire read larger, and add brilliance that bounces light back through the sapphire. If you want a ring that reads "engagement ring" at a glance — but in a stone she'll actually want to wear forever — this is the pick.
View This Ring →Pick №3 — The Green Sapphire Surprise
Green Sapphire Oval Engagement Ring
3-Stone Setting, 14kt Yellow Gold
Most people don't know green sapphire engagement rings exist. That's part of the appeal. Green sapphire is the same Mohs 9 corundum as blue sapphire, just colored by trace iron rather than titanium — same hardness, same daily-wear durability, completely different visual personality. The oval green sapphire here sits in a three-stone setting with white accent stones, mounted in 14kt yellow gold (which warms the green beautifully).
Best for someone who wants a ring nobody else will have. Reads modern, organic, and a little mysterious. Pairs especially well with warm-toned wardrobes and existing yellow-gold jewelry.

Frequently Asked Questions
What is an oval sapphire engagement ring?
A ring with an oval-cut sapphire as the center stone. The oval shape elongates the finger, makes the stone look about 10% larger than a round of the same weight, and pairs beautifully with vintage and three-stone settings.
Are oval sapphire engagement rings popular in 2026?
Yes — oval sapphires have grown faster than any other engagement ring style in the last three years. Better color story than diamonds, 30–60% lower price per carat, same Mohs 9 durability for daily wear.
What's the difference between natural and lab-grown sapphires?
Same chemical composition, same hardness, visually identical brilliance. Natural sapphires carry origin and provenance; lab-grown sapphires cost 50–70% less per carat. Both are equally durable.
How much does an oval sapphire engagement ring cost?
At Treasured & Co., approximately $1,800 for smaller lab-created pieces to $8,000+ for vintage natural sapphires with substantial diamond accents. The 6 rings featured here span that range.
Is a sapphire a good engagement ring stone?
Yes. Mohs 9 hardness handles daily wear; color flexibility (blue, teal, green, white, pink, yellow) gives design options diamond can't match. Princess Diana's iconic sapphire engagement ring (now Princess Catherine's) was an 18ct oval blue sapphire — the most-photographed engagement ring of the modern era.
What does a 3-stone sapphire engagement ring symbolize?
Three-stone rings traditionally represent past, present, and future. With a sapphire center, you also get the historical symbolism of sapphire (wisdom, loyalty, faithfulness). The side stones also make the center stone read larger.
How do I size an engagement ring without giving it away?
Borrow a ring she already wears on her ring finger. Trace the inside on paper. Bring the tracing in. Most women's ring sizes are between 5 and 7. Every Treasured & Co. ring includes one free resize within 60 days.
Where are Treasured & Co. engagement rings made?
Every piece is handcrafted in our Astoria, New York workshop, where we've operated since 1989. Free U.S. shipping; in-person fittings by appointment at 30-06 Steinway St.
