Bring jewelry for evaluation based on metal weight and gemstone quality. Receive a 90-day loan with option to extend by paying interest. Collateral remains secure until repayment.
Will I lose my jewelry if I take a loan?
No obligation to accept the loan. If you choose not to repay, items are returned after 90 days. Defaulting means items go to sale without affecting credit scores.
How are jewelry values determined?
Assessments consider precious metal weight, stone quality, brand reputation, and market demand. Condition and rarity also factor into final valuation for purchases or loans.
Do you buy broken jewelry?
Yes, we accept damaged pieces including broken chains and missing stones. Value is based on material content and potential for restoration rather than current condition.
What payment methods are available?
Loans are paid in cash immediately. Purchases require cash transactions. No credit card or financing options currently available for jewelry sales.
Are appraisals included with purchases?
