The bespoke Experience
A custom engagement ring journey, made personal
From stone to setting — designed around your story.
We work with you from the very first conversation — hand-selecting your stone, sketching your design, and handcrafting every detail in our studio. The result is a piece that is entirely, unmistakably yours.
Arcat began with a personal engagement ring search
Our Story
It started with an engagement ring Shinny couldn't find anywhere.
We're Nini & Shinny — two sisters who grew up sneaking into our mother's jewelry box, already knowing that jewelry was never just decoration. It was identity. Memory. A quiet kind of power.
When Shinny couldn't find her engagement ring — everything overpriced, nothing personal — she called her sister. Nini is a gemologist and jewelry designer. She made the ring. It was exactly right.
That moment became Arcat. Lab-grown diamonds, handcrafted in our studio, set in solid gold and platinum. Honestly priced — because you should never have to choose between beautiful and accessible.
No boutique overhead. No brand tax. No occasion required.
— Nini & Shinny

So excited when the chain arrived, it looks more stunning than from the photos! The gold chain and the beautiful green emerald compliment my skin tone so nicely. I was amazed by how many ways that I can style with this gorgeous chain. It looks beautiful with every outfit and really adds a statement to my wardrobe. Highly recommend it!

Half Eternity Ring
I’m soooo impressed with their service! I ordered custom sized rings because It’s soo hard for me to find rings my size and when they messaged me saying that they could make my rings, I was over the moon! Would definitely recommend them as they were very fast and catered to plus size ring sizes! The rings were absolutely stunning and blingy yet so elegant which is exactly what I was looking for! I will definitely order again!

Custom Halo Pearl Ring
I just got the ring in the mail and it‘s absolutely stunning. Carefully packaged too. Ever since I saw it on TikTok I wished to buy it and then I finally got it as a gift to myself :) Now I can‘t stop staring at my ring finger 🥰. Also super nice on Instagram - by far the best customer service I‘ve ever experienced. Highly recommend :)

2 Way Wear Heart Necklace
Got this as a wedding gift for a friend visiting in town, and she loved it! Had some issues with the necklace not arriving fast enough even after I paid premium for expedited shipping (Canada Post's fault). Emailed my concerns to customer service, and the owner was excellent about communicating promptly with me and offering solutions. She sent me another expedited shipping label right away so that I could send the package on to the next city my friend was staying in. Thank you, Shinny!
