Our Diamonds and Gemstones

Ethical Diamond Collection

Our curated collection of ethical, conflict-free diamonds are derive from one US supplier, via Canada or Botswana making it easier to track and guarantee the origin. Rest assured our small diamonds, or melee are ethical too! We use only full cut Canadian diamond melee in our fine jewelry because it’s not just the center stone that counts.

Our Ethical Diamond Collection contains only the top five colors of diamonds and are graded by The GIA using The 4 C's. Try our Ethical Diamond Search and find your perfect center stone online, or use our Diamond Concierge Service for assistance selecting and viewing diamonds before you purchase. Our Concierge Service fee is 100.00, and is non-refundable but fully applied to the purchase of your diamond through Laura Preshong. 

Ethical Diamond Purchasing Advantages


Craftsmanship and Ethics

 

Heirloom Stone Re-Setting

 

Laura Preshong is happy to assist in setting a family heirloom stone. All stones brought to us for use must be secured in a setting or mount. We are unable to work with loose stones, i.e. stones wrapped in paper, boxes, temporary mounts, etc. A  mandatory fee of $400 per center stone under 2.0 carats, $500 for 2.0 carats and up, and/or $50 per melee will be added to the design price to cover working with your stone. A signed Setting Waiver will be required prior to leaving any stones with us for use, including removing stones from old mounts, appraisals or design work. We require that you insure your stone prior to leaving it with us and that all stones have a current appraisal; we do not carry any type of insurance for client stones (stones not purchased through Laura Preshong), and are free from liability for loss, theft or damage. Diamonds purchased through Laura Preshong are insured FREE for one year immediately upon purchase, and are covered during the setting process. Client-owned metals and diamond melee (small diamonds) with measurements less than 2mm cannot be used in custom designs.
