Investment Grade Gems is not a gem retailer.  Our focus is primarily in our ability to find and access the most unique and valuable gems that can grow in value.  In addition to the "Four C's" (Cut, Color, Carats, and Clarity), we assert that the best rare gems often include rarity and history.  Like the best art, the story and very limited supply of a piece of art dramatically increases its value.  


Therefore, we do not concern our services to the more common gems found in the public market.  We research the rarest of gems that have proven to maintain and grow their value year-after-year.  Depending on the portfolio size, we will find and suggest the best rare gems that will build your portfolio, enhance your estate, and provide superior estate benefits. 

About us

RARITY is the fifth factor to pricing gems.  To own a "One of a Kind" gem dramatically impacts the price.  Color, cut, clarity, and and carat weight are always an issue; but the rarity and history of a gem has exponential value for gems.  While a diamond under 20 carats is easily assessed from charts, similar diamonds number in the thousands per carat.  However, a similar diamond over 50 carats has few comparable, and would be priced at tens of thousands per carat.


Our special interest is in rare and unique gems that are often valued in the millions of dollars per gem.  These gems have greater historic value growth and are mostly held in estates, museums, and large investment portfolios.
