Where your money goes

Two carats. The way it's meant to be seen.

A two-carat solitaire at a jeweler is mostly two markups: solid gold and the premium on a mined stone. The Opaline Solitaire skips both.

The center is a real lab-grown diamond. The band is 18K gold vermeil in yellow or rose, so every surface she sees is 18K gold, built over sterling silver. Want solid gold? 14K and 18K are one tap away.

All the money goes where everyone will look: the diamond.

I didn't know I had a daughter until a month ago! She is 38 and beautiful. I wanted to give her something that she could wear daily and know that she is loved! It was the perfect gift and she loves it!!

After not getting this ring for Christmas from my husband who misunderstood which ring I wanted, I ordered it myself Christmas afternoon. I have rheumatoid arthritis and know my hands don’t show off a ring as well as they once did, so I took a photo with more ring less fingers. The ring is beautiful, the customer service was unbelievably helpful, quick and went out of their way to please. I’m 66 and find shopping online exasperating but not with Awareness-Avenue!

One ring, three kinds of shine

One diamond. Nothing in the way.

The diamond

A lab-grown diamond is a diamond.

Same carbon crystal. Same hardness. Same brilliance. The Gemological Institute of America says lab-grown diamonds have essentially the same chemical, physical and optical properties as mined ones. No mine, no conflict question, no mining markup.

The shape

An oval reads bigger.

The oval carries a round brilliant's fire in a longer outline, so two carats look like more on her finger and her hand looks slimmer. It's the most-wanted shape for a reason.

The gold

18K gold on every surface she sees.

Vermeil is 18K gold over sterling silver, and ours carries 2.5 microns of it: more than ten times the minimum for ordinary gold plating. Same color and glow as solid 18K, for a fraction of the price.

Her metal, her call

Yellow, rose or white. Same price, every one.

Warm yellow, soft rose or bright white. The Opaline Solitaire comes in all three, in vermeil or solid 14K and 18K gold, and the color you choose never changes the price.

Oval cut

The oval solitaire. Nothing to hide behind.

A solitaire is honest: it's just the diamond. A two-carat oval in four prongs throws its light from every facet, and with no halo or pavé around it, all anyone sees is the stone.

White, or something rarer

A diamond in her color.

Classic white, or a blue, pink, yellow or green lab-grown diamond, picked for your ring one stone at a time. Before we set a colored diamond, we send you a video of your actual stone. You say yes, then we make the ring.

Make it yours

Put it in writing.

Her name. The date. The coordinates of where you asked. Engrave up to 25 characters inside the band, outside, or both, from +$20.

Made to order

Made for her. Not pulled off a shelf.

Good questions

Everything you want to know.

Something else? Message us. A real person answers.

Is a lab-grown diamond a real diamond?

Yes. It's carbon crystallized into diamond, just like a mined stone, with essentially the same chemical, physical and optical properties according to the GIA. It was grown above ground instead of dug out of it.

Which metals and colors can I choose?

All three colors: yellow, rose and white. In yellow or rose, choose 18K gold vermeil, 14K solid gold or 18K solid gold. In white, choose S925 Sterling Silver, or 14K or 18K solid white gold. The color you pick never changes the price.

What is 18K gold vermeil?

A thick layer of 18K gold over sterling silver. Ours is 2.5 microns of 18K gold, more than ten times the minimum for ordinary gold plating. You get the color and glow of solid 18K gold on every surface, at a fraction of the price.

Can she wear it every day?

Yes, it's made for it. Treat it like any fine ring: slip it off for the gym, the pool and cleaning products, and it will keep its glow.

Can I go bigger, or smaller?

Yes. Tap + or − under Your diamond to go from 1 ct all the way to 3 ct. The price updates as you go.

How do colored diamonds work?

Choose blue, pink, yellow or green and we find a colored lab-grown diamond for your ring. Every colored diamond is one of a kind, so we send you a video of the actual stone. We make your ring only after you approve it.

How long will it take?

Your ring is handmade to order in 10–15 business days, then ships free, insured and tracked within the US. Have a date in mind? Message us before you order and we'll plan it with you. Shipping policy

What if I don't know her ring size?

Borrow a ring she wears on that finger and check it against our size guide, or message us and we'll help you work it out.

Can I change or cancel my order?

Yes, within 48 hours of ordering. After that, your ring is already being made. Our made-to-order policy covers returns and exchanges.

What does the warranty cover?

Our Lifetime Warranty covers manufacturing and craftsmanship defects with repair or replacement, and it follows the ring if it's a gift.

Why does it cost so much less than other diamond rings?

Because you're not paying for a solid gold band or a mining markup. The Opaline Solitaire puts your money into the center diamond and finishes the band in 18K gold vermeil. Want solid gold? 14K and 18K are available.

Can I go bigger, or smaller?

Yes. Tap + or - under Your diamond and the price updates as you go.

Is it a good engagement ring?

It's the definition of one. A real two-carat oval diamond in a classic four-prong solitaire, the ring she'll never tire of.

The Opaline Solitaire

Just the diamond. Just the question.
