Tilak for AUMIKA®
Meet The Founder
Meet Tilak Kumar — Founder of AUMIKA®.
AUMIKA® was founded by Tilak Kumar, a GIA® Graduate Gemologist and US Navy combat veteran whose journey into gemstones began long before the brand itself. Coming from a traditional goldsmith family in Bharat, and trained in Surat — the diamond capital of the world — Tilak brings over two decades of diamond and gemstone experience to every AUMIKA® piece.
In 2009, Tilak founded Arun Gems International (AGI), sourcing rare diamonds and gemstones across more than forty countries. AUMIKA® is the fine-jewelry house built on that lifetime of sourcing — begin with the right stone, then quietly craft the piece around it. Each one created once, and never repeated.
A stone is not a product. It is a once-occurring geological event. The piece we build around it should be equally singular.
Are you a veteran? Tilak is too — Learn about Your Veteran Jeweler →
The AUMIKA® System
Five deliberate stages, by design.
We plan for the next thirty years of your piece—from the sourcing trip to the future trade-up evaluation.
- i.Source
Tilak personally inspects center stones across Antwerp, Mumbai, Bangkok, and Jaipur. No catalogues, only direct selection.
4–24 Weeks - ii.Design
Custom CAD and physical wax models are structured around your selected stone. Unlimited revisions at the NYC bench.
2–8 Weeks - iii.Finance
Flexible structured plans. 0% APR terms via Affirm, Klarna, or a tailored installment cycle matching the build timeline.
Tailored Terms - iv.Insure
Built-in worldwide coverage via Zillion. Protection against theft, loss, or damage with immediate checkout enrollment.
Instant Quote - v.Resale
Your natural stone's documentation holds value. Independent appraisals and trade-up cycles are pre-planned.
Lifetime Guarantee
The Distinctions
Atelier curation vs. mass inventory.
We do not hold trays of pre-made templates or commoditized databases. We source and craft for a specific individual.
Standard Retailers
AUMIKA® Atelier
Your Sourcing Story
Select diamonds from pre-made inventory dropshipped from massive lists. It feels clinical, numbers-heavy, and transactional.
A customized experience structured around the wearer, the budget, and the moment. Sourced directly from cutting floors based on human context, not SKU filters.
Expert Selection
Sales associates interpret certificates and inventory feeds. The stone is usually chosen before anyone understands the wearer.
Tilak personally inspects candidates for optical life, proportions, fluorescence, origin, and long-term value before presenting a shortlist.
Documentation & Value
Generic certificates and often heavily discounted store credits.
Tax-compliant, IRS-ready appraisals. Certified natural diamonds hold tangible liquidity, backed by a structured trade-up policy.
The Atelier
Commissioned.
Sourced.
Made for one.
Every commission begins with a private thirty-minute conversation — never a brief, never a form. It becomes a stone sourced from a name you may recognise, a setting drawn at the bench in New York's Diamond District, and a piece signed off personally by Tilak. Discretion at every stage. Documented for the lifetime of the wearer, and the one after.

Resale Integrity
Natural rarity vs. synthetic depreciation.
Slide the timeline to compare a certified natural diamond against a synthetic/lab-grown alternative. It is illustrative, not an appraisal, but it shows why AUMIKA® builds around natural rarity and future documentation.
By Year 5: industrially produced stones can face heavy price compression. AUMIKA® keeps natural-stone documentation ready for insurance, appraisal, and future trade-up evaluation.
*Illustrative only. Past market behavior does not guarantee future appreciation, liquidity, or appraisal value.

Resale Value
Held in nature.
A 100% natural diamond or gemstone carries intrinsic value because supply is finite and certification is portable. AUMIKA® documents the provenance of every centre stone so an independent appraiser, insurer, or future buyer can verify what you own — no proprietary lock-in, no synthetic substitutions, no surprises.
Our Certificates of Authenticity are issued by a GIA® Graduate Gemologist and IRS-compliant Candidate of Appraisers — accepted by major insurance companies for coverage and claims.
- Independent appraisal accepted by major insurers
- GIA® / IGI / HRD reports retain value across borders
- Trade-up conversations available — speak with AUMIKA® for current terms
- Natural, never synthetic — verified at sourcing and at the bench
