Frequently Asked Questions
Answers to what South Florida sellers ask us most about loose diamonds and gemstones.
Do you buy loose diamonds without a certificate?
Yes. A GIA or AGS certificate helps confirm grading, but it isn't required. Jon can evaluate and grade uncertified stones in person.
What is my loose diamond or gemstone worth?
Value depends on the 4Cs for diamonds (cut, color, clarity and carat) and on rarity, origin and condition for colored gemstones. We give you a firm, fair offer after an in-person evaluation, free of charge.
Do I need an appointment to sell loose stones?
We recommend scheduling ahead so we can set aside enough time for a thorough evaluation, but we can often accommodate same-day requests across Miami-Dade and Broward.
Is the consultation really free?
Yes. The consultation is free, and you are under no obligation to accept the offer.
