Sure thing! What colors do you like? The obvious safe ones are: Diamonds, Beryls: Emeralds, morganite, goshenite, aquamarine; Corundum: ruby, sapphire, fancy colored sapphire (although lab created sapphires pose issues with the sun); Topaz (high temperatures can cause breaks though and they should never sit in the sun for hours), Quartz (but be aware of the quartzes I listed that are sensitive to too much sunlight)
I feel like I am forgetting some, so I'll add more when I remember and I will make sure you see it!
