Olertis is a truly talented team of professionals! I'm very pleased with my custom ruby brooch. It's nice that they were able to use some of my previous gold (I had no desire to just throw it away or let it sit). We made a few changes to the design during production and it ended up taking a bit longer to complete (about another week), however, I think the end result was definitely worth it. I like the idea of getting something that's truly one-of-a-kind rather than buying something mass-produced. Thank you again!

I am so happy with how our custom wedding bands turned out. The pattern is detailed but not overly intricate. Both bands are extremely comfortable to wear daily, and they are perfect for what we were going for as far as something different then standard plain bands. Thank you Olertis for helping us decide on the design elements.

I decided to create a new family heirloom by converting my grandmother’s long-standing family stone into an engagement ring with Olertis. I wasn’t looking for anything trendy, just wanted something that felt right. The staff spent a considerable amount of time educating me about options and designs, but they never pushed. I think what I enjoyed the most was the respect the staff had towards the history of the stone. The final product does not feel over-designed or contrived. When I asked her to marry me, she did not miss a beat. That response said everything I needed to know.

For my ice chain, I went full throttle and Olertis delivered. They captured the exact look I envisioned. Each stone is vibrant, evenly spaced, and the whole piece feels solid in hand. The shine is tremendous but it does not appear gaudy or unrefined.

Olertis designed a tie-clip that I hadn’t considered previously myself - precisely because that’s why I opted for a custom solution. It is sleek, clean-cut and possesses adequate personality without becoming too boisterous. Overall - excellent outcome! 10/10

Upon visiting Olertis with a somewhat fragmented concept for a family crest signet ring that lacked clarity in terms of execution - Natalie somehow grasped the essence of my intent and assisted in translating it into something organized and cohesive. She removed clutter where it existed in excess, altered proportions so that it appeared balanced, and achieved an engraved design that was crisp but not too prominent (a critical component for me). The final ring feels sturdy, rests comfortably against my finger, and lacks pretentiousness - which is impressive based on how Davidmanaged this project. Great job!

Before ordering a custom piece from Olertis, I didn’t have a clear idea of the final design, which is unusual for me. Throughout the creative process, the staff at Olertis guided me toward various directions without attempting to push any extraneous elements onto me. The end result feels authentic, as if it is something that I might have selected if I could visually envision it from the beginning. Also I didn’t expect it to be ready in just three weeks, so that was a really nice surprise.

When creating custom pin badges for my work team and faced with a relatively short timeline, I was pleasantly surprised with how promptly Olertis managed each phase of production. Their efficiency allowed for timely completion of designs, revisions were seamless and all of the completed pin badges were aesthetically perfect. No part of the process seemed hurried, everyone in the team immediately recognized the superior quality of the pins upon receiving them - which is what I really hoped for.If I decide to start any other custom jewelry project in the future, I would certainly reach out to them.

Huge thanks to Mark for all his help! This project was less about developing an exciting design and more about telling a story. Since the agate stones originated from a lake where I vacationed with my mother, I desired to avoid a flashy or excessive aesthetic. Instead, Olertis transformed it into a customized necklace and kept the design minimal, allowing the stones to tell their story. This resulted in a necklace that is wearable casually, yet maintains sufficient emotional significance.

Olertis fashioned a gold pendant from several antique pieces that I had stored in a drawer. Honestly, I did not anticipate that it would be as cost-effective as it ultimately was. It also carries significant sentimental value.

Finding the right drop earrings was tougher than I anticipated. I kept noticing small issues, too rigid, too heavy, wrong angle — so we went through a few rounds of adjustments. Credit to Olertis for persevering through the back-and-forth, ultimately fine-tuning the movement of the earrings. The earrings dangle freely now and don’t get in the way at all. To date, I have worn them continuously throughout the entire day and haven’t even given them a second thought, which speaks volumes.

It was a little tough to choose tanzanite when I started shopping, but now I am super happy I chose it. The platinum setting helps keep everything clean, and the stone has such great depth — I can’t quite describe it unless you see it in person. In different lighting, the stone shifts just enough to keep things interesting. At the same time , nothing about this custom ring feels oversized or over-the-top. It’s low-key, but still stands out.

I had an excellent experience with Olertis and couldn't be happier with the final result. They truly delivered exactly what I was looking for. When they first shared the 3D design of my custom ring, I noticed an extra bezel detail that didn't quite match my vision. I'm not usually comfortable speaking up in situations like that, but when I asked about making a change, they were incredibly understanding, responsive, and easy to work with.

Their communication throughout the entire process was consistent and reassuring. Although the ring arrived slightly later than originally estimated, I was kept informed every step of the way, which I really appreciated.

Overall, the quality, service, and customer care were outstanding. I would absolutely work with them again for any future custom jewelry pieces.

The King of Timeless Elegance and Girls’ Best Friend

If you remember Marilyn Monroe, you probably know what stone she called “a girl’s best friend.” If this reference doesn’t speak to you, we hope you can remember what kind of sky Lucy was flying in. If this still doesn’t ring a bell, perhaps, you know what the hardest mineral on earth is. That’s right, we are talking about diamonds, the most coveted stones of all time. And nothing speaks of a woman’s status so highly as a diamond necklace. Such an accessory is reserved for the most special occasions and is typically worn by the rich.

However, with the advancement of modern stone-making technology, it’s possible to get a more affordable lab-grown diamond necklace. In fact, such a piece may cost half the price of a natural diamond necklace but have the same high quality and brilliance.

When talking about the styles of diamond necklaces, they can go from minimalistic to downright opulent. The former includes negligee, lariat, solitaire, and rosary. The fancier types include festoon, Edwardian style, collar, and multi-layered options. Somewhere in the middle of the spectrum there are graduated, station, and princess necklaces. By the way, the name of the last type sounds exactly like one of the most popular diamond cuts. A princess-cut diamond necklace with its square shape of stones will provide a fresh alternative to a more conventional round brilliant cut. Keep in mind that in a custom piece, square diamonds can be positioned both in a straight line or at any angle, providing more room for your imagination.

If you prefer a single string of diamonds without any special shapes, check out tennis and riviera varieties. While the former is formed from uniform diamonds of the same size, the latter features stones of various sizes that gradually range from bigger ones in the middle to smaller ones at the ends. If you prefer to wear diamonds close to your neck, why not get a custom choker or a collar? Finally, if you are a big fan of diamonds, we can make a cluster variety in your custom necklace with an opulent arrangement of variously sized diamonds to show off your high status and beauty.

Of course, nothing can outshine the sparkling king of stones, but if you’d like to complement your diamonds with other stones in one piece, you might want to consider sapphires, emeralds, or tanzanites. These gems are no less exquisite but are more affordable than diamonds and can make a perfect combination. Additionally, you can mix things up with different colors of diamonds, ranging from the most traditional colorless variety to yellow, pink, blue, red, and even black. In fact, the latter type is very rare in nature, which is why most black diamonds on the market are artificial. The good news is that this lab-grown variety is quite affordable and may serve as a great material for a custom black diamond necklace.

A personalized diamond necklace will always remain a symbol of elegance and sophistication. It is one of the most expensive and coveted gifts you can give somebody, thus, expressing how much this person means to you. Beyond their physical beauty, diamonds have inspired countless songs and poems, being the symbol of strength and everlasting beauty.
