A custom diamond ring built by Eternal Carat.
For Moda members: Moda members get wholesale pricing on lab-grown diamonds, with settings priced about 25 to 35 percent below Eternal Carat's standard rates. There is no code word to remember. Just mention Moda when you reach out and Thomas takes care of it.
A custom jeweler for the piece you actually want, from the engagement ring to the loose stone to the estate piece you are ready to part with. Everything custom is designed with Thomas and made 100 percent in the USA.
Custom engagement rings and bridal
Designed with you from the first sketch, whether you bring a clear picture or just a feeling. Thomas builds the ring around your stone, your setting, and your budget, and it is made to order 100 percent in the USA.
Other custom fine jewelry
Pendants, earrings, bands, and one of a kind pieces built to order. If you can describe it, Thomas can design and make it, from a first anniversary band to a piece that reworks stones you already own.
Loose diamond sourcing
Whether you want a lab-grown diamond or a natural, earth-mined diamond, Thomas sources loose stones to your specs and keeps the two clearly labeled, so you always know exactly which kind of diamond you are choosing.
Estate and vintage liquidation
Have estate or vintage jewelry you are ready to sell? Eternal Carat handles estate and vintage jewelry liquidation, with a transparent, consultation driven look at what your pieces are worth.
Precious metal refining
Eternal Carat refines precious metals, so old or broken gold and other metals can be recovered and put back to work rather than sitting in a drawer.
Lifetime care
Eternal Carat offers Jewelers Mutual Lifetime Care Plans, so the piece you commission can be looked after for the long run, not just the day it leaves the bench.
How a custom piece comes together.
Bespoke from the first conversation. Nothing is priced until Thomas understands the piece, and lab-grown and natural diamonds are always kept clearly distinct so you know what you are choosing.
01
Tell Thomas what you have in mind
Send the design form, or call Thomas's direct line. Share the piece, the stone you are leaning toward, and a rough budget range, and the right options come back to you.
02
A transparent look at your options
Thomas walks you through diamonds, settings, and metals, with lab-grown and natural, earth-mined stones shown side by side and clearly labeled. The market value of each is explained openly, so the decision is yours with the full picture in front of you.
03
Your piece is made in the USA
Once you approve the design, your piece is custom made 100 percent in the USA and finished by hand. When it is ready, it ships to you, or you pick it up at the Parker showroom.

Why they are on Moda
A member first, an official vendor now.
Thomas found the Moda Gold Club around 2020, spent time studying the market and how the community actually buys and sells, and in 2024 became an official Moda vendor. He rebuilt his business plan around Moda's speed and scale, which is exactly why the member perk is a real one: wholesale pricing on lab-grown diamonds, with settings priced well below his standard rates.
Eternal Carat is a paid advertising partner in the Moda vendor program, which is how this page exists. That means the member perk is sorted out up front. It does not mean Moda designs, makes, prices, appraises, or ships anything. Eternal Carat is an independent business, so the diamonds, the design, the pricing, and the piece are all Eternal Carat. Do your own diligence the way you would with any jeweler, and if anything about the partnership feels off, tell the Moda team on the report page.
Custom engagement rings and bridal, other custom fine jewelry like pendants, earrings, and bands, and loose diamond sourcing in both lab-grown and natural stones. Eternal Carat also handles estate and vintage jewelry liquidation and precious metal refining. Everything custom is designed with Thomas and made 100 percent in the USA.
The fine print.
Moda is a community and lifestyle brand, not a jeweler, an appraiser, or a diamond grading lab. This page describes an independent, paid advertising partner and is not jewelry, gemological, or financial advice.
Eternal Carat LLC, doing business as Mainstreet Jewelers of Parker, is an independent business. Every custom piece is designed and made by Eternal Carat, not by Moda. Lab-grown diamonds are laboratory-grown diamonds and are always identified as lab-grown, and natural, earth-mined diamonds are identified separately, so you always know which kind of stone you are choosing.
Pricing for any piece is set by Eternal Carat and quoted directly after a consultation. Nothing on this page is a price quote or an appraisal, and what a piece costs depends on the stone, the design, and the metals you choose.
