Dreams We Turned Into Memories
Our Promise to You
We Work To Earn Your Trust
Trust is something that is earned. Our goal is to earn your trust by offering the highest quality jewellery, being fully transparent in our practices, and working with the belief that it is our responsibility to satisfy your interests and desires in a respectful and friendly environment.
We Stand Behind Our Products
We only sell top-quality GIA certified loose diamonds and we carefully curate our extensive inventory. This allows us to provide a larger selection of truly special diamonds.
And if you change your mind, or if your custom design is not what you expected, we’ll either remake your ring at no cost to you or you can simply return your diamond within six months for a full credit.
No Pressure Sales
There are no salespeople at Jacob Mercari – only passionate jewellery design experts. As our guest, you’ll enjoy a friendly and honest customer experience with no hard ball or pressure selling.
New to the diamond buying experience? First time with custom-crafted jewellery? You’ll never make a mistake with us. Questions are always welcome and we will answer or find the answer for you. We’ll teach you everything you need to know about how to choose the perfect diamond, so you’ll feel as confident with your choice as you are with her.
Proof of Authenticity
When you purchase a Canadian-origin diamond from our collection we’ll provide you with a certificate of authenticity outlining the history, grading, and details of your diamond that you can use for insurance purposes. You’ll receive our assurance in writing that your diamond comes only from legitimate, tracked sources.
Craftsmanship is at Our Core
We work with the finest artisans and use only the highest quality alloys and materials. We go the extra mile to make sure the engagement rings and jewellery we produce are made with an extreme eye to detail and precision. If a piece does not meet our exceptionally high quality standards, we will start over and do it right at our cost.
The Finest Quality Diamonds and Gemstones
We employ only the highest-skilled jewellers and goldsmiths who work with the finest quality diamonds and gemstones.That means no brown tinges, no strong fluorescence, no surface inclusions, no cracks, and no centre black inclusions.
From top quality metal alloys to the most exquisitely cut and ethically sourced diamonds, you’ll be absolutely assured of the finest quality stone.
Completely Unique Creations
Your custom ring will be unlike any other on Earth, and she’s guaranteed to receive a ring that will be as unique and precious as your love.
Thorough Quality Inspection Process
Our attention to detail is second to none, and every piece is rigorously and thoroughly hand inspected before delivery. You’ll enjoy the peace of mind that comes with knowing each diamond has been strictly graded and expertly cut. We go well beyond the 4 C’s – carat, colour, clarity, and cut – delving into the crystal’s inner qualities and very carefully critiquing it based on its purity and various colourations – to ensure that we’ll never deliver a product that is anything less than perfect.
You Can Change Your Mind
We stand behind everything we sell. But most importantly, we stand behind you. If you select a diamond from our inventory and change your mind within six months, we will credit the full amount of the diamond cost to you. It’s our way of letting you know we’re in this together, and we will never allow our customers to experience buyer’s remorse.
Your Custom Ring Will Exceed Your Expectations
We promise you an experience free of surprises. Our artisans will craft the ultimate ring creation after detailed consultations with you. But if your custom-designed ring isn’t exactly what you had imagined, for any reason, we’ll remake it at no cost to you. It’s on us to make sure we exceed your expectations.
Unlike most jewellers, our partnership with you doesn’t end once we’ve delivered the perfect jewellery – it’s just the beginning. We provide a full range of services post-delivery to ensure you maximize your investment and fulfill her dreams.
Our free aftercare services include a ring sizing, as well as inspection and diamond or gemstone tightening to ensure a magical fit. We’ll clean your ring for the life of the ring, and we will be delighted to polish it for you before the wedding.
