Investing in Fine Art and High Jewelry
How tangible assets like certified diamonds, rare gemstones and original art hold value — and how our 12-month value promise works.
Why collectors choose tangible assets
Certified diamonds, untreated coloured gemstones and original art share three traits: finite supply, global demand and portability of value. Unlike financial assets, they can be worn, lived with and enjoyed while they are held — which is precisely why collectors have allocated to them for centuries.
What drives long-term value
Rarity, quality and documentation. A natural fancy-colour diamond with a top laboratory report, an unheated sapphire, or a signed original painting each occupy a supply that cannot grow. Documentation — certificates, grading reports, provenance — is what converts beauty into a defensible valuation.
The role of certification
Every piece at Riakoob is delivered with a certificate of authenticity and an insured valuation. For gemstones this includes independent laboratory reports; for art, provenance and artist documentation. This paper trail is essential for insurance, resale and estate planning.
Our 12-month value promise
We believe a purchase should never keep you awake at night. If the insured value of any piece you buy from us is not retained for at least 12 months from delivery, we will refund your money. It is the simplest guarantee in the industry, and it applies to every diamond, jewel, gemstone and artwork we sell.
