How We Work

From Seed to Setting

01
Diamond Growth

Each diamond begins as a carbon seed placed in a CVD or HPHT chamber, growing over several weeks under precise laboratory conditions that replicate the earth's mantle.

02
Cut & Polish

Master cutters shape every rough stone to optimise light performance — maximising the brilliance, fire, and scintillation that make a diamond breathtaking.

03
IGI Certification

All loose stones are independently graded for the 4Cs and issued a full IGI certificate. Select finished jewelry pieces are also IGI certified — noted in the product description.

04
Handcrafted Setting

Our Los Angeles jewellers set each stone by hand in our signature 14k & 18k gold and platinum mounts, finishing every piece to heirloom quality.

What We Stand For

Our Values

Ethical at Every Step

Every diamond we carry is lab grown — created without mining, without conflict, and without compromise. You get the same stone the earth would have made, with none of the cost to it.

You Get Exactly What's Described

Every piece is represented accurately — no substitutions, no misrepresentation. All loose stones are IGI certified. Select finished jewelry pieces are also certified, noted in the product description.

Insured From Our Door to Yours

Every order ships fully insured via a signature-required carrier. Your investment is protected at every step of transit.

No Minimums, Ever

Order a single piece to test a style or stock an entire collection — there is no minimum order quantity. We work with trade partners at every scale.

65–70% Below MSRP

Wholesale pricing that works for your margins. Our trade partners price competitively while maintaining healthy profitability on every piece they carry.

A Partner, Not Just a Vendor

We build long-term trade relationships. Our team is available by phone, email, or in person at our Los Angeles studio — dedicated support for every account.

Our Commitment

Sustainability

Lab grown diamonds represent one of the most meaningful shifts in the jewelry industry — a choice that delivers the same beauty with a fundamentally different impact.

Zero Mining Impact

Traditional diamond mining displaces enormous amounts of earth and disrupts entire ecosystems. Our lab grown diamonds require no mining — no land disruption, no habitat destruction, no communities displaced.

Conflict Free

Every diamond we carry is guaranteed conflict free. Lab grown diamonds have no connection to the trade that has funded conflicts in diamond-producing regions. You can wear your piece with complete peace of mind.

Lower Carbon Footprint

The energy required to grow a diamond in a laboratory is significantly less than the energy and environmental cost of mining one from the earth. We continuously work with producers who prioritize renewable energy in their growth facilities.

The Same Diamond. A Better Choice.

Lab grown diamonds are not imitations — they are real diamonds in every scientific sense. Choosing lab grown is choosing the same beauty, the same certification, and the same lasting value — with a conscience as clear as the stone itself.
