No one publishes an honest answer to this, so here is ours: where the money goes, why prices vary so much, and how to design to a budget instead of around one.
There isn't one number — and anyone who gives you one before asking about the stone is guessing. A custom engagement ring is three costs stacked together: the stone, the metal, and the making. The stone usually dominates, which means two rings that look nearly identical across a dinner table can differ in price by a factor of ten.
The useful question isn't "what does a custom ring cost" but "what can be designed well at my budget" — and the honest answer to that is: almost always more than you expect, if the budget leads the design rather than trailing it.
The stone. For most engagement rings the center stone is the largest share of the price. A diamond's cost moves with the four Cs — cut, color, clarity and carat — and moves steeply: carat weight in particular is priced on a curve, not a line, so a 2-carat stone costs far more than two 1-carat stones. Lab-grown diamonds are chemically identical to natural ones and cost noticeably less at the same size and grade; colored gemstones such as sapphires span a huge range and can carry more character per dollar than a white diamond.
The metal. Gold is priced by weight and purity, so a heavier ring in a higher karat costs more. For a sense of scale: in our wedding band builder, 14k gold is priced live by weight, and a classic 4 mm court band comes out around $651 — the estimate updates as you change the width, profile and metal. An engagement ring's band works the same way; the setting adds metal on top. Platinum is denser and typically costs more than gold for the same design.
The making. Design time, CAD work, casting, stone setting and hand-finishing. This is the part that varies least with size and most with complexity — a pavé band with forty small stones takes a setter many more hours than a solitaire, whatever the center stone cost. It's also the part that determines whether the ring still looks right in thirty years.
Usually not — and this surprises people. A retail ring's price includes the brand's margin, store inventory and advertising. A commissioned ring's price is the stone, the metal and the hours of the people who design and make it. At the same budget, custom tends to buy more intention: the stone you chose, proportions matched to the hand that will wear it, and no compromise baked in by whatever happened to be in the case.
What custom does ask of you is time — a real design process takes weeks, not minutes. If you're working toward a date, start early and say so.
Opening a commission carries a $60 design fee, which reserves your designer's time for three sketched concepts and a photorealistic 3D render — and is credited in full toward your ring's final price. Once your design is defined, you receive a detailed quote before anything is made, so the full cost is on the table before you commit to production. Nothing is cast until you approve the final design.
Your budget is part of the conversation from the start. If a design brief and a budget don't meet, we'll say so plainly and show you what will.
Not necessarily. With a custom ring you aren't paying for a brand's retail markup, inventory or advertising — you're paying for the stone, the metal and the making. At the same budget, custom usually buys you more intention, not less ring.
The old "three months' salary" rule was an advertising campaign, not financial advice. Spend what is comfortable for you. A thoughtful design at a modest budget beats a generic one at a large budget — tell your designer the number first and let them design to it.
Consider a lab-grown diamond, which costs noticeably less than a natural stone of the same size and quality, or a colored gemstone such as a sapphire. Prioritizing cut over carat also makes a diamond look livelier — and often larger — than its weight suggests.
Once your design is defined you receive a detailed quote, so you know the full cost before committing to production. The $60 design fee paid at the start is credited toward the final price. See how a commission works.
