Custom Engagement Rings & Fine Jewelry Design

Whether you have a specific vision for your dream engagement ring or need guidance selecting the perfect gemstone, we make the custom jewelry process straightforward and enjoyable. We work directly with you every step of the way. At Jewelry Express Works, our master jeweler, Igor, uses modern 3D design to help map out your ideas before handcrafting the piece right here in our Brookline shop, proudly serving clients from Boston, Cambridge, and the greater metro area.

Please note: Our 3D modeling process is reserved exclusively for creating new custom engagement rings, wedding bands, and original fine jewelry, rather than for repair work. We cast all of our custom pieces exclusively in traditional precious metals, including gold, platinum, and sterling silver.

We handle every step on-site at our Brookline storefront. By designing, casting, and setting the stones locally, we ensure your ring is crafted to exceptional professional standards without ever leaving our secure bench.

Our Custom Specialties Include:

  • Custom Engagement Rings & Wedding Bands
  • Natural Gemstone & Lab-Grown Diamond Jewelry
  • Bespoke Pendants, Necklaces, and Fine Earrings
  • Transforming Family Stones into Modern Bridal Designs

A Note on Heirloom Stones & Outside Mountings: We love reinventing sentimental heirloom diamonds and gemstones by crafting brand-new custom settings around them. Igor evaluates stone viability and design specs—including metal thickness and prong security—prior to project approval to ensure a lifetime of daily wear. Setting stones involves bench pressure that can occasionally damage delicate gems. We do not work with soft or brittle gemstones (such as natural emeralds, opals, pearls, or heavily fractured stones) to ensure the safety of your property. Our preference is always to custom-craft the setting from scratch so it is built specifically around your stone for a secure fit and balanced seat depth. If you are bringing in a premade outside mounting, Igor will inspect both items in person to confirm a proper structural fit.

Note: We use email to explore initial concepts and scheduling at no cost. Metal choices, final design specs, and exact binding quotes are completed during your in-person consultation (or shortly after, allowing Igor time to calculate bench labor or source specific accent stones).

Our Brookline Custom Jewelry Design Process: Step-by-Step

From your first conversation with us to your finished piece, custom crafting typically takes 3 to 4 weeks (subject to CAD revisions and bench capacity). Final project totals are calculated simply as: Selected Gem Price + Custom Mounting Design (plus applicable MA sales tax).

  1. Step 1: Free Initial Consultation & Estimate ($0):
    We discuss your design concept, review metal options, and evaluate feasibility together during a free, no-obligation consultation (in person or via email). Igor will review your ideas and calculate an estimated price range before any financial commitment is required.
  2. Step 2: 3D CAD Design & Stone Sourcing Deposit:
    When you are ready to officially begin your custom 3D CAD design or have us order specific loose stones for your project, we collect a structured deposit—100% of which applies directly toward your final ring balance:
    • $350 Custom Design & Lab-Grown Deposit: For sourcing specific lab-grown diamonds, or for designs using our in-house inventory and customer-supplied heirlooms. Covers your 3D CAD design, up to 2 revisions, and a physical 3D resin model to try on. Applied 100% to your finished ring total. (Design deposits are non-refundable once CAD drafting begins).
    • $500 Vault Natural Gemstone Deposit: Required when sourcing rare or origin-certified earth-mined diamonds and sapphires from supplier vaults (explore active stones in our Gemstone Vault). Covers fully insured priority transit to Brookline, a 7-day private shop viewing window, custom 3D CAD design (up to 2 revisions), and a physical 3D resin try-on model. Applied 100% to your finished ring total, or transferred toward an alternate vault stone. (Deposits covering insured transit and CAD are non-refundable).
  3. Step 3: 3D Digital Rendering & Physical Resin Model:
    We draft your 3D digital model and print a physical 3D resin model. You can view and try on this model in our store to get a feel for the exact scale and proportions before we pour any metal.
  4. Step 4: On-Site Casting & Clean Up:
    Once you approve the resin print, Igor melts your chosen metal and casts the mounting right here in our workshop.
  5. Step 5: Stone Setting & Finishing:
    We carefully set your diamonds or gemstones and give the jewelry a beautiful final polish so it is perfectly ready to wear.

Frequently Asked Questions

Can I bring in my own diamond or gemstone for a custom setting?

Yes! We regularly design and build brand-new custom rings around client-supplied diamonds, sapphires, and rubies. All outside gems require an in-person bench evaluation by Igor to verify structural integrity and take precise measurements. To protect your sentimental jewelry from setting pressure, we do not accept high-risk or brittle gems (such as natural emeralds, opals, pearls, or heavily fractured stones).

Can you set my stone into an outside premade setting I already own?

Crafting our mountings from scratch remains our strong preference, as building a setting specifically around your stone ensures a proper fit, balanced profile, and long-term security. However, if you already have both a stone and a premade setting, bring them by our Brookline shop. Igor will inspect both items in person to evaluate metal quality, seat depth, and prong alignment before determining whether they can be set safely.

Do you offer standalone insurance appraisals?

As a small local bench jeweler, we do not offer standalone insurance appraisals for outside or inherited jewelry. However, for all custom jewelry created in our shop, we email you a comprehensive documentation summary upon completion. This details your piece's metal purity, carat weights, and gemstone specifications so you can easily insure it with your provider of choice (such as Jewelers Mutual or your personal insurer).

How long does a custom ring take to complete?

Custom projects typically take 3 to 4 weeks from your initial consultation through final polish. Timeline variation depends on CAD revision speeds, bench labor complexity, and current shop capacity.

Can I see what my ring will look like before metal is poured?

Yes. Every custom project includes a digital 3D CAD rendering and a physical 3D resin model printed right here in our Brookline shop. You can try on the resin model in person to review the exact scale, profile height, and proportions before we move forward with casting.

What if my finished ring needs a size adjustment?

We provide one complimentary sizing adjustment on your custom ring after completion to ensure a comfortable fit.

When is the remaining payment due?

Your initial deposit covers your 3D design phase and stone sourcing, and applies 100% toward your project. The remaining balance (plus applicable MA sales tax) is due upon pickup when your finished ring is ready. We do not offer financing or payment plans.

Do you offer a warranty on custom jewelry?

We stand behind all craftsmanship from Igor's bench. Every original custom piece created in our shop includes a Craftsmanship Guarantee against structural and manufacturing defects upon completion. To help maintain your piece, we provide complimentary lifetime cleaning and prong inspections whenever you drop by our Brookline shop.

What is covered: Defects in metal casting, solder points, or stone setting workmanship (including complimentary replacement of small accent stones under 0.05ct within the first year of normal wear).
What is not covered: Normal wear over time (such as surface scratches or naturally thinned prongs), accidental impact damage (bent metal or crushed shanks), lost center or major stones, or alterations done by outside jewelers.

Note: A warranty covers bench craftsmanship, not loss or accident. Upon pickup, we provide detailed jewelry specification paperwork so you can easily insure your piece right away through specialized insurance (such as Jewelers Mutual or your homeowner's policy) for complete coverage against loss, theft, or accidental damage.
