Love the proportions

The stone is the perfect size — not so small it disappears, not so big it looks costume. Just right.

Thank you so much for this beautiful review! We're thrilled you love your Estelle ✨

Husband's first jewelry success

My husband has historically been TERRIBLE at picking out jewelry. For our 10th anniversary he asked our daughter to help and they ordered Estelle together. I unwrapped it and burst into laughing tears because for the first time in 10 years he picked something I actually love. The sparkle, the dainty chain, the size of the stone — everything is exactly my style. Bravo to whoever designs ONYXELLE pieces.

Switching from real diamond to this

I have a real solitaire I usually wear daily but I'm scared of losing it at the gym or pool. This Estelle has become my everyday replacement and honestly nobody can tell the difference. I leave my real one in the safe now.

This made our day! Thank you for taking the time to share your experience.

Treated myself, no regrets

Bought it after a rough week as a treat and now it feels like a little reminder to keep showing up for myself. Looks luxurious, feels luxurious.

This made our day! Thank you for taking the time to share your experience.

Catches every light

Honestly I find myself standing in patches of sunlight just to watch this thing sparkle. Magical little piece.

We absolutely love this. Welcome to the ONYXELLE family!

Honestly stunned by the quality

I have been burned by online jewelry so many times that I almost did not order. So glad I changed my mind. The stone has real fire to it under light, the chain is dainty but solid, the clasp feels secure, and the packaging was beautiful. Already considering ordering the matching earrings.

Made my week

Sometimes a small piece of beauty changes your whole mood. This did that for me.

We're so happy it passed the daily wear test — that's exactly what we design for. Thank you!

Date night staple

This has become my go-to necklace for every date night. Sparkles in restaurant lighting in the most flattering way.

This necklace catches the light from every angle, I am obsessed.

Genuine luxury feel

From the packaging to the necklace itself, it really does feel like a luxury experience.

We absolutely love this. Welcome to the ONYXELLE family!

Wedding day approved

Wore this on my wedding day under my dress and the photos turned out gorgeous. So glad I went with this over a more expensive piece.

Lovely, chain is delicate

I love the look and the sparkle but the chain is quite delicate so I am careful with it. Holding up well so far but I would not yank on it.

Quiet elegance

Understated but draws compliments everywhere I go.

Looks like I spent a fortune

Everyone keeps asking where I got my new diamond necklace. The sparkle is that convincing. Best kept secret of my jewelry box.

Cute but not blown away

It is a cute necklace and it does sparkle. I just wish the overall piece felt a little more substantial. Wear it occasionally.

Did not expect to love it this much

I bought this on impulse during a sale and I am genuinely shocked at how much I love it. The first thing that struck me was the packaging — the box feels luxurious, the inside is lined nicely, you get that little 'unboxing moment' that good jewelry should give you. Then the necklace itself: dainty without being fragile, sparkling without being flashy, balanced perfectly. I wear it daily and have stopped reaching for anything else. If you are debating, just buy it. You will not regret it.

We're so happy it passed the daily wear test — that's exactly what we design for. Thank you!

My new signature necklace

I have been searching for a 'signature' necklace for years — something I could wear every day, dress up or down, and never feel underdressed in. Estelle is it. The brilliant cut catches light constantly which means it never looks flat or boring. The chain sits at the perfect spot on my collarbone. The gold tone works with both warm and cool outfits. I wore it to a black-tie event last week and to school dropoff this morning. Both times felt completely right. ONYXELLE clearly designed this to be a forever piece and it shows.

Thank you so much for this beautiful review! We're thrilled you love your Estelle ✨

Beach trip approved

Took it to Mexico last month — saltwater, sunscreen, sand, pool. Still gleaming. Did not lose its sparkle one bit.

Thank you for trusting us with such a special moment! Sending love.

Birthday treat

Treated myself for my 30th and I have zero regrets. Feels like a real luxury item every time I put it on.

Better than the brand-name version

I compared it side by side with a much pricier brand piece I own and honestly Estelle wins for sparkle. The cut is just better.

Thank you for trusting us with such a special moment! Sending love.

Cannot stop wearing it

Three weeks in and I have not put on another necklace once.

Christmas gift for daughter

I bought this for my 17-year-old daughter for Christmas. She is at the age where 'cool' jewelry usually means trendy stuff that will not be in style by spring. I wanted something more timeless. The look on her face when she opened it told me everything. She has worn it every day since — to school, to soccer practice, in the shower, sleeping. She told me last weekend it is her favorite gift she has ever received. Worth every dollar.

Veronica Ross
Delicate and dainty

Exactly the look I wanted. Not chunky, not heavy, just elegant.

Thank you for trusting us with such a special moment! Sending love.

Solid clasp

I lose necklaces because the clasps fail. This one has a tiny but very secure clasp and I never worry about it falling off.

G
Gabrielle Green
Cute layering piece

Works beautifully in a layered look. On its own it is a little understated for me but layered it is gorgeous.

M
Maya Barnes
Brilliance is real

I have a couple of pieces from much pricier brands and the sparkle on this one honestly competes. The cut on the stone is impressive for the price.

Thank you for trusting us with such a special moment! Sending love.

Three months in — still loving it

I am giving this review three months later because I think jewelry reviews after 3 days are useless. Three months of daily wear, including the shower, gym, sauna, beach, lots of sweat, lots of soap, perfume, sunscreen. The verdict: still perfect. Sparkle has not dulled, the gold has not faded, the chain has not weakened. I have actually had to buy a second one because I want to give one to my best friend for her birthday and could not bear to part with mine. ONYXELLE I am a fan for life.

This made our day! Thank you for taking the time to share your experience.

Pretty necklace, simple style

Exactly as described — a simple, pretty solitaire. Not flashy but elegant. Glad I got it.

Thank you for trusting us with such a special moment! Sending love.

Anniversary win

My husband bought this for our anniversary and I love it more than the real diamond pieces I own. The brilliance is incredible and it goes with everything. So happy with this.

This made our day! Thank you for taking the time to share your experience.

Great value for the price

Honestly really good quality for what I paid. Took off one star because I wish the chain came in a longer option.

We absolutely love this. Welcome to the ONYXELLE family!
