All diamond jewelry sold by Diamonds On The Key is "Natural Earth Mined Diamonds"!

Diamonds On The Key offers Birthstone Fancy Colored Diamonds in a variety of colors, such as Yellow (most popular fancy color!) PinkBlueGreen and Black to fit a variety of budgets! 

The 10.03-carat “Mediterranean Blue” diamond, graded fancy vivid blue by GIA — the highest color grade for blue diamonds — will debut at Sotheby’s Geneva on May 13, estimated at $20 million.



Rarer than rare, only 0.3% of diamonds are blue, and even fewer reach this vivid intensity at over 10 carats. A true masterpiece of nature and cutting craftsmanship.

Natural-color Green Diamonds are extremely rare and can be classified as faint, light, intense, vivid or deep. 


A green diamond is said to be the second rarest natural color of a diamond with fancy red being the rarest. 

Natural Pink Diamonds are among the rarest and most valuable gems on Earth, with vivid stones selling for over $2 million per carat. Their high value comes from extreme rarity and exceptional beauty.

At Diamonds On The Key, we believe in using our passion for fine jewelry to give back to the community. We are honored to support meaningful causes that make a real impact via donation of silent auction items, gift certificates, raffle prizes, trunk show shopping events, and in person attendance. 


We recently had the privilege of participating in three incredible events, helping raise funds for organizations dedicated to children and families in need. Here’s how your support helped make a difference:

We were delighted to host a stunning trunk show at The Colony Palm Beach, with a portion of sales benefiting the Children’s Home Society of Florida.


This annual luncheon, co-chaired by Tere Borgia, brings together generous supporters to help children and families in need.


We’re grateful to be part of such a heartfelt cause!
