About Us

Hello & Welcome to CustomDiamonds.ca!

We are a boutique family-run Jeweller located in Toronto (Thornhill), Ontario. We specialize exclusively on custom/bespoke jewellery, all of which are 100% designed and fabricated here in Canada. Additionally, all raw materials, precious metals, and gemstones are sourced ethically and conflict-free. Our promise to our customers is simple: exceptional service & craftsmanship at "rock" bottom prices.

From engagement rings, wedding bands, bracelets, pendants/necklaces, to earrings, we have the experience and expertise to create virtually any type of jewellery that your heart desires. Our precious gem offering is also comprehensive and the lowest priced in Canada. We offer only the finest natural & laboratory-grown diamonds, emeralds, sapphires, rubies, opals, and others.

What our Design Process is like

  1. We begin most projects via an initial free consultation. To schedule one, please email us or use our Contact Us Form. If you already have a specific idea/design in mind, including details & reference images would help greatly. If you’re still exploring different design options, we’d be happy to help you narrow it down! 
  2. After our consultation, we’ll provide you with an exact quote & timelines. Pricing will include all design and manufacturing costs, and comparative diamond/gemstone options.
  3. Once you select your diamond/gemstone(s) and would like to proceed, we ask for a $300, or a 30% non-refundable deposit (whichever is greater) on the price of the centre stone to cover import & shipping fees associated with your stone.
  4. Once your diamond/gemstone(s) arrive in Toronto, we can either meet in-person to showcase these stones for you, or we can schedule a video call. In either option, we’ll showcase all the unique characteristics of your stone, and conduct a full inspection live to verify its authenticity.
  5. To begin the design work, we ask for a further 50% deposit. For a classic design, approximately 3 weeks later your custom jewellery piece should be complete! For particularly complex works, a common timeframe is 5-6 weeks.
  6. Once finished, we also offer the option of having your jewellery professional appraised (+2 days). Remaining balance will be due upon local delivery/pickup, or prior to shipping.

Our Team

Jonathan & Shoshana Mostovoy

How we Began

Back in 2023, I, Jonathan, had the very difficult task of purchasing an engagement ring for (my now wife) Shoshana. I wanted the ring to be truly unique and incorporate design elements inspired by some of Shoshana’s passions: art, nature, and music. The few jewellers that I visited were not interested in the large amount of work involved, and anyone who was, provided price-points that were unfathomable.

The solution: become our own jeweller. Over the course of a few weeks, I developed great relationships with suppliers, casters, polishers, setters, and appraisers here in Toronto. The finished ring was beautiful, and with all these new contacts and knowledge, we later discovered a prime opportunity. 

But Why Are Your Prices So Low?

Two main reasons: we charge a considerably smaller margin than everyone else, and we do not hold much inventory. The vast majority of "well-known" brick-and-mortar or online jewellery stores charge between a 500-1,500% margin on the sales of precious stones. Yes, that’s right, we didn’t make a typo, the markup is that enormous! The whole argument that classical jewellers make about "this doesn't have good resale value, buy THIS instead" may be counter-argued by the simple fact that they're charging you 10x the fair value - of course it won't hold its value. Our goal, in comparison, is to provide incredible quality jewellery at a genuinely fair price.
