Borrow against Diamonds

Borrow Now

Release funds against your diamonds - quickly and at the lowest interest rates.

Your diamond could be the route to a short-term, low-interest, hassle-free loan. Unbolted will lend up to 70% of your diamond's value.

Valuing your diamond

For an accurate valuation we'll first need information regarding the 'Four C’s':

Cut: Round brilliant, princess or emerald cut? Is your diamond cut to ideal proportions and do you have certificates?
Colour: Do you have that rare colourless diamond or the intense blue of Hope Diamond?
Clarity: Are your diamonds flawless or are they slightly included but eye-clean?
Carat: How big is your diamond?

Certification.

We also look for certificates from institutes such as the GIA and AnchorCert. If these aren't available, our specialists can grade your diamond. We use Rappaport information combined with auction house knowledge. This helps us provide the maximum loan amount.

Diamond set in jewellery? No problem. If we can, we'll grade it in its mount. However, to properly grade larger diamonds we have these un-mounted by the industry's finest jewellers.
