Thirty-three years after sitting down at a jewelry bench with a dream and a vision, Henry Grossbard created the first Original Radiant Cut Diamond by combining an emerald cut’s elegant shape with a round stone’s fiery brilliance. For those who love to be different, the Original Radiant Cut makes square and rectangular diamonds magnificent again.

Diamond Pricing at Vinciguerra Jewelers
Diamond pricing depends on the Four C’s: carat, color, clarity, and cut. Pricing also depends on band quality, setting style, and whether you’re choosing a natural or lab-grown diamond. Because every piece is different, we don’t publish a one-size-fits-all price list.
What we can tell you: we work with a wide range of budgets, and our team is committed to helping you find the best diamond for your investment. For custom engagement rings, we offer complimentary consultations at our downtown St. Louis location to discuss your vision and budget before you commit to anything.
To get a sense of value, a small, high-quality diamond can cost the same as a larger, lower-quality stone. Understanding the Four C’s is the first step, and we’re happy to walk you through it in person.
Frequently Asked Questions About Diamonds
How much does a custom engagement ring cost in St. Louis?
Custom engagement ring prices at Vinciguerra Jewelers vary based on your design, diamond selection, and metal choice. We offer a complimentary consultation at our downtown St. Louis location to discuss your budget and vision. We’ll work with you to create a stunning custom ring that fits your investment level.
Where can I get my engagement ring appraised near downtown St. Louis?
Our certified appraisers provide professional jewelry appraisals for engagement rings, diamonds, and fine jewelry at our 701 Market St. location. We offer detailed appraisals for insurance purposes, estate planning, or personal records. Call to schedule your appointment.
Should I insure my diamond?
Yes, insuring your diamond protects you financially if it falls out, gets lost or stolen, or is significantly damaged. Without coverage, replacement comes entirely out of pocket. We strongly recommend insuring any diamond purchase, and our appraisers can provide the documentation your insurance provider will need.
What are lab-grown diamonds?
Lab diamonds are created through advanced processes that replicate the natural conditions under which diamonds form. They possess the same optical, chemical, and physical properties as mined diamonds and are visually indistinguishable to the naked eye. They’re also an ethically and environmentally conscious alternative for those who value responsible sourcing.
How is a diamond priced?
A diamond’s price is based on its Four C’s: carat, color, clarity, and cut. When assessing a ring’s total value, appraisers also consider band quality and setting. Our team is happy to walk you through what each factor means and how it affects your investment.
Which matters more: diamond size or quality?
Both are important. A small, high-quality diamond can cost the same as a larger, lower-quality one. The right balance depends on your personal priorities and budget. Our staff will help you weigh those tradeoffs in person.
What’s the difference between “carat” and “karat”?
Carat refers to a diamond’s weight. Karat describes the proportion of gold in an alloy. For example, 18-karat gold is 18 out of 24 parts gold.
Can I shop for engagement rings on weekends?
Yes, we’re open Saturdays 9 AM–1 PM for engagement ring consultations and shopping. Browse our diamond collection or discuss custom design options with our team at our downtown St. Louis showroom.
Do you offer ring resizing in downtown St. Louis?
Absolutely. Our skilled jewelers provide expert ring resizing for engagement rings, wedding bands, and fashion rings, ensuring a proper fit while preserving the integrity of your piece. Stop by our downtown St. Louis store, or call ahead to schedule an appointment.
Where can I sell or consign diamond jewelry in St. Louis?
Vinciguerra Jewelers offers professional consignment services for diamond rings, luxury watches, and fine jewelry. Visit our downtown location for a free evaluation or call to learn about the consignment process.
How important is the diamond’s setting?
The setting determines how the diamond attaches to the ring and plays a major role in its overall appearance. Matching your diamond’s size and cut with the right setting is key to achieving the look you want, whether that’s minimal and understated or bold and elaborate.
