Our Philosophy

Every piece has
a true value.
We find it.

Most people buying or selling diamonds, jewellery, or gold have no idea whether they are getting a fair deal. Retail marks up. Pawn shops underpay. Online platforms are opaque. Gemma Viva was built to fix that.

We buy directly from private clients at prices that reflect true market value — not convenience margins. If we are not the best buyer for your piece, we will find one. Our network spans dealers, collectors, and auction houses across Hong Kong, Dubai, and Australia.

For those looking to acquire — diamonds, jewellery, or gold — we source exactly what you need, at the right price, with full certification and independent verification. No showroom pressure, no inflated retail.

We Buy Your Pieces
Diamonds, jewellery, and gold — we offer fair, transparent prices based on real market data. No lowballing. We tell you exactly what your piece is worth and why.
We Find You a Buyer
If selling directly to us isn't the best outcome, we leverage our global network of collectors, dealers, and auction channels to maximise what you walk away with.
We Source to Buy
Looking to acquire a specific stone, piece, or gold allocation? We find it at fair value — GIA-certified, independently verified, with no retail inflation.
We Invest Alongside You
For clients who want to hold hard assets long-term, we structure investment-grade diamond and gold portfolios — with full provenance, custody, and liquidity planning.

Three Ways We Serve You

01
Sell Your Assets
Have diamonds, jewellery, or gold you want to sell? We provide a confidential, no-obligation valuation — then either buy directly at a fair price, or connect you with our global network of buyers to achieve the maximum possible outcome. We come to you, wherever you are.

02
Buy with Confidence
Looking for a specific diamond, piece of jewellery, or gold allocation? We source it through our trade network at true wholesale value — fully certified, independently appraised, with no retail premium. Engagement rings, investment stones, gold bars: we find the right piece at the right price.

03
Invest for the Long Term

How It Works

Simple. Transparent. Personal.

01 ——
Tell Us What You Have
Share details or photos of your diamonds, jewellery, or gold — or describe what you're looking to acquire. We respond personally, not with an automated form.
02 ——
We Value It Honestly
We provide a full, transparent assessment — what your piece is worth, what comparable pieces are trading for, and what outcome is realistically achievable for you.
03 ——
We Buy or We Find a Buyer
We either purchase directly at a fair price, or activate our global network of dealers, collectors, and auction channels to maximise what you receive.
04 ——
You Walk Away Satisfied
Fast, discreet, and settled. We handle logistics, paperwork, and transfer — wherever you are in the world. No surprises, no hidden fees.

You deserve
more than retail.

Whether you are buying, selling, or holding — the difference between a fair outcome and an excellent one is expertise, network, and someone working for you rather than against you. That is what Gemma Viva provides.

Fair Valuations
Transparent, market-based pricing. We explain every figure — no mystery, no manipulation.
Global Reach
Buyers and sellers across HK, Dubai, Australia, and beyond. We find the best match, not just the nearest one.
We Come to You
No need to visit a showroom. We handle assessments, logistics, and transfer wherever you are located.
Total Discretion
Every client interaction is private. We do not discuss, share, or disclose any client details or transactions.

Your diamond is worth more than
anyone with a retail margin will tell you.
