Lab-grown diamonds are changing the perspective of how people see fine jewelry, and in Los Angeles, the shift is quite clear.

From engagement rings to daily-wear studs to fully custom pendants, there’s no shortage of brilliant options, with no damage linked to mining.

2. VRAI - Zero-Emission Sustainable Diamonds

VRAI

Address: 8472-A Melrose Place, Los Angeles, CA 90069

VRAI LA store displays an elegant collection of lab-made diamonds. The collection includes round, oval, and even hexagonal ones. Pear, cushion, heart, and marquise are also part of it. Emerald shape, too. It’s a mix that brings something for every taste. Each lab diamond shape is designed for a different style and event. The collection includes rings for engagements, wedding bands, solitaires, halo rings, earrings, necklaces, and even men’s jewelry.

All diamonds are grown using clean technology without carbon emissions. They are then set into recycled 14k or 18k gold. Some may prefer minimal bands while others love dramatic necklaces. VRAI creates both with care and modern taste.

Why Choose VRAI?

  1. Zero-Emission Certified Diamonds – Grown sustainably in a hydro-powered foundry for truly carbon-neutral production 

  2. Extensive Shape Variety – Offers more than 30 diamond shapes, including fancy cuts like marquise, trillion, heart, and unique signature designs 

  3. Art Gallery Showroom – West Hollywood boutique features a striking diamond bar and private rooms designed by Cass Calder Smith 

  4. Cut-for-You™ Customizations – Bespoke options let you choose diamond shape, size, and setting, aided by on-site experts

  5. Transparent & Direct Pricing – Vertical integration from creation to retail eliminates middlemen, with guaranteed diamond value and full lifetime-care coverage

3. Global Rings Jewelry - Downtown LA Custom Designs

Globalringsjewelry

Address: 550 South Hill Street, Suite #920, Los Angeles, CA 90013

For over four decades, Global Rings Jewelry has built trust through lab-grown diamond jewelry. Their lineup includes elegant rings, bracelets, earrings in hoop or stud style, timeless necklaces, and men’s pieces as well. Shapes like cushion, emerald, princess, oval, round, marquise, radiant, heart, asscher, and pear are just some of what’s available. You can even search for diamonds easily with their custom tool.

One-of-a-kind engagement ring or a band to celebrate years together, their in-house production makes it easier to get exactly what you want. That means more control, better results, and prices that feel right. Each design carries personal touches built on skill and tradition.

Why Global Rings Jewelry Stands Out?

  1. Wide Lab‑Grown Collection: Offers everything from diamond earrings and bands to large solitaire engagement rings and loose stones

  2. Customization Friendly: Flexible to swap in lab-grown stones for mined or create fully custom designs with expert jewelers.

  3. 30‑Day Money‑Back Guarantee:  Shop with confidence, returns accepted within 30 days 

  4. Ethical & Transparent: Lab-grown diamonds look identical to natural ones to the naked eye, and all diamonds are ethically sourced.

4. Icing On The Ring - Highly Certified Jewelry

In Downtown Los Angeles, Icing On The Ring brings together one of the largest collections of GIA-certified lab-grown diamonds.

Take a look at their “evertrue” ready-to-ship line; it includes pre-set engagement rings in white, yellow, and rose gold, plus platinum settings. They also feature tennis bracelets, stud earrings, and men’s jewelry. Both lab-grown and natural diamonds are available, and Moissanites too. Their style leans toward classic looks built with today’s methods. Every stone is conflict-free, and the pieces are built to last. These designs work well for daily wear and special days alike.
