We advise clients on diamond acquisitions. Natural diamonds are brokered privately, while lab-grown diamonds are available through our online shop.

Our private studio operates with a high level of discretion and quiet sophistication. Consultations are arranged by appointment, usually at your location or another convenient setting.

For your convenience, we are also available for discreet delivery at Henderson Executive Airport, including aboard your jet, with prior arrangement. Confidentiality is always maintained, and we execute NDAs upon request for additional assurance.

We offer custom-weight cast bullion, priced by the gram, starting at one troy ounce. Our cast gold is priced at a 6% premium, currently $174/g.

For clients pursuing the highest tier of bullion, our beautiful minted gold is sold only in 25-kilogram increments. Minted gold acquisitions often include private jet travel to Las Vegas and a memorable delivery experience.

Payment for our bullion is accepted via traditional wire transfer. For minted gold bullion, we also accept publicly traded securities tendered through our U.S. brokerage partners. Our distinctive stock-for-bullion option allows you to convert market holdings directly into physical gold as part of a strategic reallocation or exit. For long-term wealth-preservation strategies, we can also coordinate introductions to approved IRA custodians for tax-advantaged gold placement.

See the market as we see it

We track tens of thousands of wholesale diamonds around the world, and also monitor economic conditions that could affect the price of gold.

Our analytics reveal natural diamond market conditions such as time-on-market, wholesale pricing behaviors, and shifts in global inventory. For gold, we continuously run our algorithm against macroeconomic signals to identify opportune moments for buying and selling.

This research shapes everything we do. It informs how and when we source diamonds, where deep wholesale opportunities appear, and how we help clients take advantage of market timing.
